Tsavorite: The Rare and Stunning Green Gemstone

As a gemstone enthusiast, I have always been fascinated by the beauty and rarity of tsavorite. This green garnet, first discovered in Kenya in the late 1960s, has gained popularity in recent years for its vivid green color and high brilliance.

Tsavorite is a member of the garnet family, and its color ranges from a yellowish-green to a deep forest green. It is often compared to emerald, but tsavorite is actually more durable and has fewer inclusions. This makes it a popular choice for engagement rings and other types of jewelry that require a gemstone with both beauty and durability.

In addition to its physical properties, tsavorite also has a rich history and cultural significance. It is believed to have healing properties and is associated with the heart chakra, making it a popular choice for spiritual and holistic practitioners. Its rarity and unique color also make it a symbol of wealth and luxury. Overall, tsavorite is a gemstone that offers both beauty and meaning, making it a truly special addition to any collection.

Tsavorite History

Geological Formation

Tsavorite garnet is a rare and valuable gemstone that was first discovered in Tanzania in the late 1960s. It belongs to the grossularite species of the garnet group and is characterized by its vivid green color, which is caused by the presence of chromium and vanadium. Tsavorite is found in metamorphic rocks that have been subjected to high pressure and temperature, such as schists and gneisses.

The formation of tsavorite is closely linked to the geological processes that shaped the East African Rift system, which extends from Ethiopia to Mozambique. This region has a complex geological history that involves the collision of several tectonic plates, the eruption of volcanoes, and the erosion of ancient mountain ranges. The resulting rocks and minerals provide the ideal conditions for the formation of tsavorite deposits.

Discovery and Naming

The discovery of tsavorite is credited to Campbell Bridges, a British geologist and gemstone dealer who was exploring the bushlands of Tanzania in the late 1960s. Bridges noticed some green crystals in a streambed and recognized them as a new type of garnet. He named the gemstone after the Tsavo National Park, which is located near the area where it was found.

Tsavorite quickly gained popularity among collectors and jewelry designers for its unique color and rarity. Today, tsavorite is mainly mined in Tanzania and Kenya, although small deposits have also been found in Madagascar, Pakistan, and Sri Lanka.

In conclusion, tsavorite garnet has a fascinating history and origin that is closely tied to the geological processes that shaped the East African Rift system. Its discovery and naming are credited to Campbell Bridges, who recognized the gemstone’s potential as a valuable addition to the world of tsavorite stones and jewelry.

Physical and Chemical Properties

Color Variations

Tsavorite is a green variety of garnet that ranges in color from a yellowish green to a bluish green. The intensity of the green color depends on the amount of chromium and vanadium present in the crystal structure. The most valuable tsavorites are those with a vivid green color, without any brown or yellow secondary hues.

Chemical Composition

Tsavorite belongs to the garnet group of minerals, which are silicates with a general chemical formula of X3Y2(SiO4)3. The X site is usually occupied by calcium, magnesium, or iron, while the Y site can be occupied by aluminum, iron, or chromium. Tsavorite has the chemical formula Ca3Al2(SiO4)3, with the chromium and vanadium impurities responsible for its green color.

Crystal Structure

Tsavorite has a cubic crystal structure with a hardness of 7.5 on the Mohs scale. It has a refractive index of 1.74-1.76 and a specific gravity of 3.50-3.55. Tsavorite is commonly found as small, well-formed crystals, but can also occur as massive or granular aggregates.

In terms of gemstone quality, tsavorite is highly valued for its rarity, durability, and beauty. Its vivid green color, combined with its excellent clarity and brilliance, make it a popular choice for high-end jewelry.

Overall, tsavorite is a fascinating gemstone with unique physical and chemical properties that make it a true treasure of the earth.

Sourcing Tsavorite

As a gemstone enthusiast, I have always been fascinated by tsavorite. This beautiful green gemstone is a member of the garnet family and is known for its vivid green color. In this section, I will discuss the primary locations and mining methods used to source tsavorite.

Primary Locations

Tsavorite is primarily found in Kenya and Tanzania, although smaller deposits have also been discovered in Madagascar and Pakistan. The majority of tsavorite deposits are found in the Tsavo National Park region of Kenya. The area is known for its rugged terrain, which makes it difficult to access and mine. However, the rough conditions are what make tsavorite so valuable and rare.

Mining Methods

Mining tsavorite is a difficult and time-consuming process. The gemstone is typically found in small pockets within the host rock, and miners must use specialized tools to extract the rough stones. The most common method used to mine tsavorite is open-pit mining. This involves removing large amounts of rock and earth to expose the tsavorite deposits. Once the deposits are exposed, miners use hand tools to extract the rough stones.

Another method used to mine tsavorite is underground mining. This involves digging tunnels into the earth to reach the tsavorite deposits. This method is more expensive and time-consuming than open-pit mining, but it allows for more precise extraction of the gemstones.

In conclusion, sourcing tsavorite is a challenging process that requires specialized knowledge and tools. However, the beauty and rarity of this gemstone make it a valuable addition to any collection.

Tsavorite as a Gemstone

As a gemstone, tsavorite is a beautiful and rare variety of garnet that is highly valued for its vivid green color. It was first discovered in Tanzania in 1967, and later in Kenya in 1971. It has since become a popular gemstone among collectors and jewelry enthusiasts.

Quality and Grading

When it comes to grading tsavorite, the most important factor is its color. The ideal tsavorite color is a vivid green, similar to that of an emerald. The color should be evenly distributed throughout the stone, without any noticeable color zoning or brownish tones. The clarity of the stone is also important, with fewer inclusions leading to a higher quality stone.

Tsavorite is graded using a system similar to that of diamonds, with a scale ranging from AAA to A. AAA grade tsavorite is the highest quality, with a bright, vibrant green color and excellent clarity. A grade tsavorite is still a beautiful stone, but may have slightly less vibrant color or more visible inclusions.

Cut and Shape

Tsavorite is typically cut into faceted shapes, such as round, oval, or cushion cut, to maximize its brilliance and sparkle. The cut of the stone is also important, as it can affect the stone’s overall appearance and value.

When choosing a tsavorite, it is important to consider the cut and shape of the stone, as well as its color and clarity. A well-cut tsavorite with a vibrant green color and excellent clarity can make a stunning addition to any jewelry collection.

In conclusion, tsavorite is a beautiful and rare gemstone that is highly valued for its vivid green color and excellent clarity. When choosing a tsavorite, it is important to consider its quality and grading, as well as its cut and shape, to ensure that you are getting the best possible stone.

Tsavorite in Jewelry

As a gemstone, tsavorite has become increasingly popular in jewelry design. Its unique green color and brilliance make it a sought-after gemstone for both casual and formal occasions.

Setting Types

Tsavorite is often set in various types of jewelry, including rings, earrings, necklaces, and bracelets. The most common setting types for tsavorite include prong, bezel, and pave. Prong settings use small metal prongs to hold the gemstone in place, while bezel settings use a metal rim to encircle the gemstone. Pave settings use small metal beads or prongs to hold multiple gemstones in place.

Care and Maintenance

To keep tsavorite jewelry looking its best, it is important to take proper care of it. Tsavorite has a hardness of 7.5 on the Mohs scale, making it relatively durable, but it can still be scratched or damaged if not cared for properly. To clean tsavorite jewelry, it is recommended to use warm soapy water and a soft-bristled brush. Avoid using harsh chemicals or ultrasonic cleaners, as they can damage the gemstone.

Overall, tsavorite is a stunning gemstone that can add a touch of elegance and sophistication to any jewelry piece. Whether it’s a simple tsavorite stud earring or an elaborate tsavorite and diamond necklace, this gemstone is sure to make a statement.

Market and Value

Pricing Factors

As a gemstone, tsavorite is valued based on a number of factors that determine its quality and rarity. The most important of these factors are color, clarity, carat weight, and cut. Tsavorite is prized for its vivid green color, which is caused by the presence of chromium and vanadium in the crystal structure. The most valuable stones are those that exhibit a pure green hue without any brown or yellow undertones. Clarity is also an important factor, with eye-clean stones commanding a premium over those with visible inclusions. Carat weight is another important factor, with larger stones being rarer and therefore more valuable. Finally, the cut of the stone can greatly affect its value, with well-proportioned and symmetrical cuts maximizing the stone’s brilliance and fire.

The market for tsavorite is relatively small compared to other gemstones, which can make it difficult to find high-quality stones for sale. However, there are a number of reputable dealers and auction houses that specialize in tsavorite, and it is possible to find loose tsavorite or finished jewelry featuring tsavorite for sale online or in person. Prices for tsavorite can vary widely depending on the quality of the stone, with top-quality stones commanding prices of several thousand dollars per carat.

Investment Potential

While tsavorite loose is not as well-known as other gemstones like diamonds or rubies, it has been gaining popularity in recent years as collectors and investors seek out rare and unique stones. As a relatively new gemstone, tsavorite has not yet reached the same level of mainstream recognition as other gems, which means that prices are still relatively low compared to other stones of similar quality and rarity. This presents an opportunity for investors to purchase tsavorite at a relatively low cost with the potential for significant appreciation in value over time.

However, it is important to note that investing in gemstones is not without risk. The market for tsavorite is still relatively small, which means that prices can be volatile and difficult to predict.

Buying Tips

When it comes to buying tsavorite, there are a few things to keep in mind to ensure that you get the best value for your money. As someone who has been in the gemstone industry for several years, here are my top tips for buying tsavorite:

  1. Choose a reputable seller: It’s important to buy from a reputable seller who can provide you with a certificate of authenticity. This will give you peace of mind knowing that you’re getting a genuine tsavorite and not a synthetic or imitation stone.

  2. Check the clarity: Tsavorite is a type II clarity gemstone, which means that it can have inclusions. However, the fewer inclusions the stone has, the more valuable it is. Be sure to examine the stone carefully under a loupe or microscope to check for any visible inclusions.

  3. Look for a vivid green color: Tsavorite is prized for its intense green color, which should be bright and vivid. The color should be evenly distributed throughout the stone, without any brown or yellow tints.

  4. Consider the cut: A well-cut tsavorite will have good brilliance and fire, making it more valuable. Look for a stone that has a symmetrical cut with good proportions.

  5. Compare prices: Tsavorite is a rare gemstone, so it can be quite expensive. Be sure to compare prices from different sellers to ensure that you’re getting a fair price for the quality of the stone.


Additionally, the value of a gemstone is highly subjective and can be influenced by a number of factors, including changes in fashion and taste. As with any investment, it is important to do your research and work with a reputable dealer or advisor to ensure that you are making informed decisions.

By following these tips, you can ensure that you’re buying a high-quality tsavorite that will be a valuable addition to your collection. See also this related article: Emerald Pendant Gold Necklace: A Timeless and Elegant Accessory.
