Garnet

The name Garnet is primarily derived from the Latin word “Granatus” meaning “Seed-Like” or containing “Many Grains”. Granatus is specifically referring to “Pomum Granatum”, meaning pomegranate. The crystals of this gemstone are rounded and similar in size, shape and colour to the red kernels of the pomegranate fruit. During the 14th century, the word “Granatus” evolved into the middle English term “Gernet”, this term was used to describe something which was dark red. The term gernet would eventually evolve into the modern word Garnet. Some reports have credited Albrecht Von Bollstadt, a 13th century, German philosopher and theologian with coining the name. He used the Latin word “Granatus” to describe the gemstone Garnet.
The name Garnet is used to describe a group of differently coloured minerals, with a similar crystal structure and related chemical composition. In this mineral group, there is a wide array of varieties, of which there are six main gemstone quality varieties and five main hybrid varieties.

Primary Garnet Varieties

• Pyrope: Chemical composition: Mg3Al2(SiO4)3 magnesium aluminium silicate. This variety ranges in colour from deep fiery red-orange to purplish red. Pyrope from the Czech Republic is known as Bohemian Garnet. The main deposits are found in the Czech Republic, Italy, Germany and Arizona. In Arizona, ants can bring small pyrope to the surface, earning them the name “Anthill Garnets”.
• Almandine: Chemical composition: Fe3Al2(SiO4)3 iron aluminium silicate. This variety ranges in colour from deep red to purplish red or brownish red. Almandine or Almadite as it is also known, is the most common variety within the Garnet group. Its name is derived from Alabanda, an ancient city located in present-day Turkey, where the gemstone was traded. The main deposits of Almandine are found in India, Brazil, Madagascar, Sri Lanka and the United States.
• Spessartite: Chemical composition: Mn3Al2(SiO4)3 manganese aluminium silicate. Spessartite, also known as Spessartine, ranges in colour from fiery orange to soft yellow-orange or deep reddish brown. It gets its famous “mandarin” orange colour from high concentrations of manganese. The redder tones are the result of this variety mixing with Almandine. It was first discovered by Martin Klaproth in 1797 in the Spessart Mountains of Bavaria in Germany. Current major deposits are located in Namibia, Nigeria, Madagascar and Tanzania.
• Grossular: Chemical composition: Ca3Al2(SiO4)3 calcium aluminium silicate. Grossular, also known as Grossularite derives its name from “Ribes Grossularium” which is the botanical name for gooseberry. The name refers to the original discovery of this pale, translucent green variety found near the Vilui River in Yakutia in Siberia. Grossular is the most colour diverse variety of the Garnet group, it forms in nearly every colour except blue. The main deposits of Grossular are located in Kenya and Tanzania. Other significant deposits are located in Sri Lanka, Mali, Madagascar, and South Africa.
  Within the Grossular variety there are a number of sub-varieties:

1. Siberian Grossular, pale gooseberry green.
2. Tsavorite, vivid emerald green.
3. Hessonite, cinnamon orange/brown.
4. Merelani mint, light pastel green.
5. Leuco-Garnet, transparent and colourless, very rare.
6. Hydrogrossular, typically opaque, green, pink or white in colour. Sometimes used as a Jade substitute and sold as Transvaal Jade.

• Andradite: Chemical composition: Ca3Fe2(SiO4)3 calcium iron silicate. Of all the varieties of Garnet, Andradite has the highest lustre and brilliance (fire) often surpassing even that of Diamond. Andradite was first discovered by Jose Bonifacio de Andrada e Silva near Drammen in Norway. The most significant deposits of Andradite are located in Russia, Namibia, Madagascar, Italy, Mexico, Japan, and the United States.
  Within the andradite variety there are a number of sub-varieties:

1. Demantoid, vibrant emerald green colour. Russian Demantoid often contain radiating asbestos fibres called horsetail inclusions, which are highly prized and very expensive. With museum-grade specimens reaching, $500,000 per carat at auction (2025 reports).
2. Melanite, an opaque jet-black gemstone with a highly reflective submetallic lustre. Melanite was a popular gemstone for mourning jewellery during the Victorian Era.
3. Topazolite, a yellow to golden brown gemstone which is similar to Topaz, hence the name. Gemstone quality specimens of Topazolite are extremely rare.
4. Rainbow Garnet, this sub-variety of Andradite has a metallic iridescent play-of-colour.

• Uvarovite: Chemical composition: Ca3Cr2(SiO4)3 calcium chromium silicate. Uvarovite is a very rare variety of Garnet and is almost always formed in a vibrant emerald green colour, due to its high chromium content. Uvarovite crystals are typically formed very small, too small to actually be faceted. Each crystal is usually only 1 to 3mm in size and so this gemstone is left attached to the host rock, which is typically chromite or serpentinite.

Garnet Hybrid Varieties

During the formation process, different chemical elements can swap places within the same crystal structure. Which leads to hybrid varieties forming. It is for this reason that there is such a wide variety of colours and types of Garnet.

• Rhodolite: purplish-red, raspberry colour. Hybrid of pyrope and almandine.
• Malaya: peach, pink or red-orange colour. Hybrid of pyrope and spessartite.
• Mali Garnet: yellow to greenish-yellow colour. Hybrid of andradite and grossular.
• Colour-Change Garnet: changes colour depending on the light, blue-green in daylight and purple-red in incandescent light. Hybrid of pyrope and spessartite typically, a rare gemstone.
• Star Garnet: deep purple-red to reddish black in colour. Hybrid of almandine and pyrope.

Formation: The formation of Garnet can take place through one of two different geological processes, either metamorphism or igneous events.
Metamorphic Formation: Metamorphism is the most common way in which Garnet forms. The process starts when sedimentary rock such as shale that is rich in aluminium is compressed by tectonic plate movement. This activity generates very high temperatures and pressure, which breaks down the sedimentary rock’s chemical bonds. Elements such as aluminium, iron and magnesium, then recombine and crystallise as Garnet. Metamorphism can also occur when hot magma comes into contact with cooler rock such as limestone. This will cause the limestone to heat and calcium-rich Garnets such as Grossular will then form.
Igneous Formation: Varieties of Garnet like spessartite can form in igneous rock such as granite and pegmatite. These form directly inside silica-rich magma as it cools. Pyrope Garnets in host rock such as kimberlite form under extreme pressure deep within the Earth’s mantle. Pyrope is then brought to the surface through volcanic eruptions.
Over time, the host rock can become eroded by weathering and so release the harder Garnet gemstone. Which gets washed downstream and accumulates in placer deposits, also called alluvial deposits. It is in these placer deposits that much of the mining for Garnet is concentrated, particularly due to the ease of both discovery and extraction. The world’s main Garnet (gemstone quality) deposits are located in Kenya, Tanzania, Mozambique, Madagascar, Sri Lanka, Brazil, Namibia, Nigeria, and Russia.

Treatment: Garnets are very rarely treated, they naturally have vibrant colour and excellent clarity making treatment unnecessary. Although with that said it is worth noting that some varieties are treated even if rarely done so.

• Heat Treatment: Andradite can be heat-treated at a low temperature to improve brilliance and clarity. Demantoid can be heat-treated to remove brownish tones and to intensify its green colour. Hessonite and malaya can be heat-treated to brighten their colour.
• Oil/Resin: Some varieties like hessonite can be prone to inclusions which reach the surface. These gemstones can have a surface coating of wax or oil applied, which will fill any surface cracks and improve the stone’s clarity. It should be noted that this treatment is not permanent and will need to be reapplied from time to time. A polymer or resin can also be used as a surface treatment, which is more durable. However, it should be noted that resin treated gemstones are heat-sensitive and chemical-sensitive. As such these gemstones should not be cleaned using a subsonic or steam cleaner.
• Dyeing: Low grade red Garnet can be dyed to improve its colour.

Durability: Garnet overall is considered a tough and durable gemstone, with a Mohs hardness rating of 6.5 to 7.5. Within the Garnet group, varieties can vary slightly. Almandine, pyrope and spessartite have the hardest rating of 7.25 to 7.5, making them suitable for everyday wear. Including in rings and bracelets which are more prone to impacts. Varieties such as demantoid and hessonite are slightly softer, with a Mohs rating of between 6.5 to 7. These are more suitable for use as earrings and necklaces if they are to be worn every day, as they are more protected from impacts.
Garnet’s cleavage is indistinct, which means it does not have a plane of weakness within its crystal structure. As such its toughness would be rated at fair to good.

• Sunlight: Garnet is sunlight stable and its colour will not fade even with prolonged exposure to UV rays.
• Heat: Under normal conditions, Garnet is not heat sensitive. Very high heat, such as a jeweller’s torch can cause colour change or for the stone to crack.
• Chemicals: As a general rule, it is best to keep your Garnet jewellery in a separate compartment within your jewellery box. Since the gemstone can be scratched by harder gemstones and in turn it can scratch softer gems. Alternatively, you could place it in a soft cloth pouch if you do not have a separate compartment. If your Garnet gemstones are set in silver, it is recommended to store them in an anti-tarnish bag or with a silica packet if you are using a soft cloth pouch.
• Cleaning: The safest and most recommended way to clean your Garnet jewellery is with a bowl of warm, soapy (mild) water and a soft toothbrush. Leave your jewellery to soak for about 10 minutes. Then use the toothbrush to gently clean to avoid catching the brushes bristles in your jewellery settings which may dislodge the gemstone(s). Then rinse well under warm running water, always place the plug in the sink while you do this to prevent small items like earrings accidentally slipping down the drain. Note, do not use toothpaste as it typically contains abrasive particles which can leave micro-scratches on the gemstone. Ultrasonic or steam cleaners are not recommended because if the gemstone has tiny inclusions which you cannot see. Then the use of these machines can cause it to crack.

History

Garnet has a very long history dating back over 5,000 years. The earliest known mining of this gemstone was in the Arabian desert of Egypt, located between the Nile Valley and the Red Sea. The Wadi Sikait and Wadi Gimal regions were famous for producing Emerald however, these areas also produced significant quantities of almandine and pyrope garnet. The Aswan region also produced Garnet. The majority of mining in these areas was from placer deposits, where the gemstone accumulated. This made both discoveries of the stone and mining much easier. Garnet mined from these areas was sent to workshops in cities such as Memphis and Thebes. Where specialised gem cutters would process them. These gem cutters developed sophisticated techniques for their time, to cut and polish gems. They would use emery dust, which is an abrasive dust made from quartz or corundum to grind the garnet stones into flat slices. They were also able to drill holes in Garnet beads, by using copper-tipped drills to which they added abrasive dust. They also perfected the cloisonne technique of joining flat pieces of Garnet together with strips of gold. A huge achievement for their time.
By 500BC, Sri Lanka had established itself as a major supplier of gemstones and a significant supplier of Garnet. The island produced a number of different varieties including, Almandine-Pyrope which was historically called “Ceylon Ruby”, Hessonite which was known as “Cinnamon Stones” and Rhodolite which is also known as “Elahera Garnet”. Mining in Sri Lanka mainly was from placer deposits (alluvial deposits) and mining methods were typically small-scale dredging of shallow rivers or pit-head mining. All of these mines were owned and controlled by the Sri Lankan monarchy, who orangised the mining, gem cutting and export of all gemstones. From Sri Lanka, Garnet and other gemstones were traded with the ancient Romans and Greeks, along with the Persian empire.
From around 300 BC, India became a significant producer of Garnet. Particularly Almandine Garnet, which was historically called “Raktamani” meaning “Blood-Red Jewel”. The anicent port city of Arikamedu on India’s east coast was a major bead producing hub and trade center for Garnet. From here Garnet was exported to the Roman empire from the 1st century onwards. The trade in Garnet from India reached its peak during the 16th to 17th centuries under the Mughal empire. The Mughal emperors themselves were prolific collectors, as well as regulating the exporting of gemstones through duties, royal workshops and exclusive ownership rights of all gemstones that weighed more than 5ct. At this time, there was a sophisticated network of trade routes both by land and sea, along which Garnet was transported to destinations in Western and Central Asia and throughout Europe. From the 19th century onwards, deposits of gemstone quality Garnet in India largely became depleted. This has led India to concentrate its mining efforts on industrial-grade Garnet production, of which India is currently a major global supplier.
In the Czech Republic, the mining of Garnet dates back thousands of years with the stone being sourced from riverbeds in prehistoric times. However, in the 16th century Emperor Rudolf II established Prague as a gem-cutting centre. He also granted himself preferential rights to purchase the largest stones. As a note, Bohemian Garnets are typically found in secondary deposits and have already been subjected to weathering. As such Bohemian Garnets tend to be small, typically less than 6mm in size. These Garnets are of the pyrope variety with an intense deep red colour and are found almost exclusively in the Bohemian Central Highlands near Prague. In 1609, these gemstones were named “Granatus Bohemus” which is Latin for “Bohemian Garnet(s)”, historically these gems were refereed to as carbuncles. Later on in 1762, Empress Maria Theresa introduced export regulations which banned uncut Garnet from being exported. This created a monopoly on the cutting and polishing of the stone within the kingdom of Bohemia.
During the Georgian Era, Garnet was a popular choice of gemstone and considered appropriate for daywear as opposed to Diamonds, which were considered evening wear. The gemstone would typically be cut as cabochons, rose cuts, or table cuts, which were very popular at the time. These gemstones would be typically set in closed-back settings and foil-backed. The foil-backing was designed to intensify their deep red colour and to make them glow under candlelight. Garnet riviere necklaces were the height of Georgian fashion, as were matching parures. Deep red Garnets were also used along side Jet or black enamel in mourning jewellery at this time.
During the Victorian Era, the popularity of Garnet exploded into a global fashion phenomenon. This was largely driven by two factors. Firstly, new discoveries were made in Bohemia (Czech Republic), which made Garnet more affordable and widely available. Secondly, Queen Victoria was a great lover of gemstones Garnet included and following the death of Prince Albert in 1861. The Queen entered a prolonged period of mourning, during which she popularised dark red Garnets in her mourning jewellery along with Jet. These deep red Garnets were sombre enough for mourning while at the same time they were elegant and beautifully complemented black attire. Bohemian pyropes are naturally small and so to maximise their impact. Victorian jewellers would pave-set them in tight clusters that would make the metal setting beneath them almost invisible. This tight clustering of shimmering red gems created the “Pomegranate Look”, iconic of Victorian Garnet jewellery. Each individual gem in these tight clusters was a rose cut, which was flat-bottomed and a faceted dome top. This rose cut was specifically designed to glow and flicker under candlelight ot lamplight, making the Garnets appear as though they had an inner fire. During the Victorian Era, a Garnet Engagement Ring was a very popular choice, symbolising love, loyalty and trust.
In 1851, Demantoid, a vibrant emerald-green sub-variety of Andradite was discovered in the Ural Mountains in Russia. The name Demantoid is derived from the German words “demant” and “oid” which translates to “diamond-like”. It earned this name from its exceptional brilliance, rivaling diamond’s brilliance. This stone often contains the highly prized inclusions of radiant asbestos fibres called “horsetail inclusions”. It was a favourite gemstone of the Russian Czars and frequently used by Carl Faberge.
In the 1960s, Rainbow Garnet was discovered in the Umba Valley in Tanzania. This beautiful stone can colour-change, being blue-green in daylight and turning to purple under incandescent light.
In 1967, Tsavorite was discovered by Campbell Bridges in Tanzania. He also went on to find further deposits of Tsavorite in Kenya in 1971. Henry Platt, of Tiffany & Co., named this gemstone after Kenya’s Tsavo National Park. Tsavorite is a vivid emerald green colour, a sub-variety of Grossular and was marketed as a more durable alternative to Emerald.
In 1991, “Mandarin Garnet” (Spessartite) was discovered in Namibia. Previous discoveries of Spessartite were a brownish-red colour. However, this discovery in Namibia was a vibrant neon orange colour, often called “Fanta-Orange”. Mandarin Garnet is extremely rare and in high demand by luxury jewellery brands.

Folklore

Garnet has a rich and extensive folklore dating back thousands of years to ancient times. In the bible, it is said that Noah used a carbuncle gemstone quite likely a large Garnet to illuminate the Ark. During the great flood that lasted forty days and nights, neither the sun or moon shone. God told Noah to place precious stones and jewels in the ark to provide light. The light from this carbuncle gemstone (Garnet) glowed more brightly by night than by day and so Noah was able to tell night from day. Also in the bible, King Solomon was said to have received four precious stones set in a ring from God, delivered by angels. The four stones were Lapis Lazuli, Topaz, Emerald and Garnet (carbuncle). Each stone granted Solomon power over a different realm. Garnet granted him power over spirits and demons, which enabled him to bind them into his service.
The ancient Egyptians believed this was a sacred and powerful gemstone that could protect them both in this life and the afterlife. They associated Garnet with the sun god, Ra who was the ruler of the sky, earth and underworld. They used this stone as a powerful talisman to ward off evil spirits and misfortune. They also believed it provided protection and safe passage in the afterlife. Pharaohs and high-ranking individuals were often buried with Garnet necklaces. Garnet jewellery and objet d’art have been found in Tutankhamun’s tomb as well as other pharaohs. The Egyptians also used this stone for medicinal purposes, believing it could purify the blood and alleviate heart palpitations or panic attacks.

Greek Mythology: The ancient Greeks referred to Garnet as “Anthrax” meaning “burning coal”, they also commonly called it “Pyropos” meaning “fiery-eyed”. They associated this stone with Persephone, goddess of spring, vegetation and Queen of the underworld. Legend has it that Hades, King of the underworld, gave Persephone pomegranate seeds to ensure she would return to the underworld. Since Garnet is so similar in appearance to pomegranate seeds, the gemstone came to symbolise reunion and fidelity. For this reason, the Greeks seen it as a “Stone of Travellers” and they would give it as gift to a loved one who was undertaking a journey to ensure a safe journey and that they would be reunited again. They believed Garnet held an inner light and often called it “Nuktalopos” meaning “Lampstone”. It was said that it would allow the wearer to see in the dark if worn as a necklace. They also believed it could dispel terrors of the night. Greek warriors wore the stone as a powerful talisman, in the belief that it could grant them strength and courage, along with protection on the battlefield.

Roman Mythology: The Romans highly prized Garnet, seeing it as a symbol of authority and power. They associated it with Mars, god of war, due to its deep red colour. Roman soldiers would wear it as a powerful talisman, believing it could grant them strength, courage and protection on the battlefield. The Romans widely used Garnets that were engraved to make signet rings. These signet rings were then used to show the individual’s rank and also to stamp wax seals on official documents. Wealthy individuals would also have craved Garnet signet rings made with various images of either one of the gods or a magical symbol. These signet rings were then believed to have increased powers from the engraved image and the ritual used in creating it. Roman travellers would wear Garnet as a talisman on their journeys for protection. The stone was said to glow or sparkle brightly if danger was approaching and so warn the wearer. Roman physicians claimed Garnet could ward off disease and the plague. They would also place the actual gemstone inside a wound in the belief it would accelerate the healing process. It was also widely believed to purify the blood and improve circulation.

Medieval Europe: During the middle-ages, royalty would use Garnet as a detection tool and to neutralise poison. In the case of wine or drink they would commonly drop a Garnet into the cup. The Garnet would then neutralise any poison if present. In the case of food, the process was more elaborate. A proving tree called a Arbe d’epreuve was placed in the centre of the table. From the branches of this tree was hung various precious stones, including Garnet. The food was then placed near this tree, if the food was poisoned, it was said that the gemstones would change colour, start to sweat or start to vibrate. Garnet rings were also dipped into soups or sauces and the stone inspected afterwards to determine if the food was safe or not. There has been reports of nobility grinding Garnet into a fine powder and consuming it with food in the belief that this would act as a permanent antidote to poison.
Knights and crusaders wore this gemstone in the belief that it would protect them and ensure their safe return home. They also believed that Garnet could help coagulate blood and so stop bleeding. It was common for knights and crusaders to set Garnet gemstones into the hilts of their swords and daggers.
Medieval physicians used the stone to ward off the black death or as a remedy for the black death. They also used it as a treatment for depression and nightmares. As it was said to dispel sadness and bring gladness, which led this stone to be called the “Happy Gem”.
A belief from Roman times, which still persisted during the middle-ages was that gemstones could be enchanted and so increasing their normal virtures. This could be done by performing a ritual while the gemstone was being carved with a specific image. Different precious gemstones were assigned specific images and symbols. A list of these images and symbols is detailed in the “Book of Wings” by Ragiel, a 13th century grimoire. In the case of Garnet it details the following:
“The well-formed image of a lion, if engraved on a Garnet, will protect and preserve honors and health, cure the wearer of all diseases, brings him honors and guards him from all perils in travelling.”
In the Catholic church, Garnet symbolises the blood of Christ and his crucifixion. The church believed that Garnet bestowed fidelity and constancy upon the wearer who wore them rightfully. However, the same stone would cause discord to whomever wore it without a legitimate right to wear it. Abbots and bishops would often wear pectoral crosses and episcopal rings containing Garnet. It was also widely used in liturgical objects and to make rosary beads.
