Tsavorite is a gemstone belonging to the garnet family. It is known for its beautiful green color, which ranges from bright, intense greens to deep forest greens. Tsavorite is prized for its color, luminosity, and rarity, making it a popular choice for jewelry.
Origin: Tsavorite was first discovered in the 1960s in Tanzania, near Tsavo National Park, hence the name. Later, additional deposits were discovered in Kenya. Composition: Tsavorite is a crude garnet, which is a calcium aluminum silicate. The green color is due to the presence of vanadium and chromium in its crystal structure.
Color: The color of tsavorite is its most prominent feature. It is often compared to the color of emerald, but tsavorite tends to have a more vibrant and intense green color. Color can vary depending on the trace elements present, with shades ranging from yellowish green to bluish green. Transparency and Gloss: Tsavorite is usually transparent, allowing light to pass through and creating a vibrant sheen. It has a vitreous (glassy) luster when polished.
Durability: Tsavorite is a relatively hard gemstone, with a Mohs hardness of 7-7.5 on the scale. This makes it suitable for everyday use in jewelry such as rings, earrings and pendants.
Rarity and Value: Tsavorite is considered one of the rarest gemstones in the world. Its rarity, combined with its outstanding color and quality, contributes to its high value in the gem market.
Care and Maintenance: Tsavorite jewelry should be handled with care to avoid scratches and bumps. Tsavorite gemstones should be cleaned with mild soap and warm water, using a soft brush to remove dirt or debris. Ultrasonic cleaners and steam cleaners should be avoided.
Synthetic Tsavorite: Synthetic or man-made tsavorite in the laboratory is also commercially available. These are man-made versions that have the same chemical composition and physical properties as natural tsavorite. However, they are generally less valuable than natural tsavorite gems.
As with any gemstone, it is best to purchase tsavorite from reliable sources to ensure quality and authenticity. The Gemological Institute of America (GIA) is a trusted organization that provides gem grading reports and certifications for tsavorite and other gemstones, which can help verify their authenticity and quality.
Geological formation and sources
Tsavorite forms in metamorphic rocks under specific geological conditions. Gemstones are often found alongside rocks such as gneiss, shale, and marble, which have experienced high temperatures and pressures deep within the earth’s crust.
The main sources of tsavorite are in East Africa, especially in Tanzania and Kenya. The initial discovery of tsavorite was made in 1967 by a Scottish gemologist named Campbell Bridges near Tsavo National Park in Tanzania, near the Taita Hills. Subsequently, substantial deposits were also found in neighboring Kenya, especially in the Elephant, Taita-Taveta and Kuranze regions.
The formation of tsavorite is related to geological processes associated with the Mozambican Orogenic Belt, which spans several countries in East Africa. This belt is characterized by tectonic activity and the collision of continental plates, leading to rock metamorphism and the formation of gem deposits.
Specific conditions required for tsavorite formation include the presence of high-quality metamorphic rocks, such as those found in the Mozambique belt, and the availability of certain chemical elements, in particular are vanadium and chromium. These factors are important in giving the green color to garnet crystals.
Mining tsavorite is a difficult process due to the remote and rugged terrain where the gem is found. Small-scale mining operations are common, using hand tools and manual labor. Miners often work under extreme conditions to extract tsavorite from hard rock formations.
It should be noted that while East Africa is the main source of tsavorite, small deposits of the gem have also been discovered in other parts of the world, including Madagascar, Pakistan, Sri Lanka and Brazil. However, deposits in East Africa remain the largest and most sought-after source of tsavorite.
Properties of Tsavorite
Tsavorite, a green garnet, has a number of remarkable properties that contribute to its beauty and appeal. Here are the main properties of tsavorite:
- Chemical composition: Tsavorite is a calcium aluminum silicate belonging to the group of garnet minerals. Its chemical formula is Ca3Al2(SiO4)3.
- Color: Tsavorite is famous for its vibrant and intense green color. Color varies from yellowish green to bluish green, with variations in saturation and tint. The color is often compared to that of emerald, but tsavorite has its own brilliance and vibrancy.
- Transparency: Tsavorite is typically transparent to translucent. Overall, it exhibits good clarity, with little visible impurities or impurities. Gem-quality tsavorite with excellent clarity is appreciated.
- Hardness: Tsavorite has a hardness of 7 to 7.5 on the Mohs scale so it is relatively durable. It is scratch resistant and can withstand daily wear and tear.
- Refractive Index: The refractive index of tsavorite ranges from 1.734 to 1,759. This property determines the gem’s ability to bend and reflect light, contributing to its brilliance and sparkle.
- Density: The specific gravity of tsavorite ranges from 3.65 to 3.75. This density measurement helps identify and distinguish tsavorite from other gemstones.
- Crystal system: Tsavorite crystallizes in a dodecahedron, forming 12-sided crystals. However, it is often found as irregularly shaped granules or crystals with no impurities suitable for cutting.
- Origin: The main sources of tsavorite are in East Africa, more precisely in Tanzania and Kenya. Other small deposits were discovered in Madagascar, Pakistan, Sri Lanka and Brazil.
- Optical properties: Tsavorite exhibits polychromaticity, which means it can display different colors when viewed from different angles. It also has a vitreous (glassy) luster when polished.
- Heat Sensitivity: Tsavorite is generally heat insensitive, which means it can be safely heated for jewelry cleaning or cleaning purposes without the risk of significant color change or damage.
These properties contribute to the attractiveness and value of tsavorite gemstones. It is important to consider these characteristics when evaluating and selecting tsavorite for jewelry or gem collections.
