Tsavorites are rare vanadium garnets that are a variety of grossulars with an attractive emerald-green color. The vibrant green color of Tsavorite garnet makes it a popular choice for jewelry. It is often used in engagement rings, earrings, pendants, and other types of jewelry.
Tsavorites can be of yellow-green, green, or blue-green hues. The most expensive stones are those of a bright green color. Such tsavorites are not very common on the jewelry market. Lower-priced items are those that are too light or dark in tone and have low color saturation. Most of the stones that come on the market are under one carat in weight and have a rather light coloring. It is worth mentioning that the presence of a natural green coloring is due to the presence of additives of chrome and vanadium in tsavorites. For this reason, natural green garnets of grossular colored by iron ions cannot be attributed to tsavorites. Jewelers know these stones under the trade names of mint garnets, green garnets or grossulars, or Mali garnets.
Tsavorites have appeared on the jewelry market quite recently. The first samples of tsavorites were found in 1967 by the geologist C. R. Bridges in the northern part of Tanzania. At that time there was a ban on taking precious stones out of the country. Because of this Bridges had to search for tsavorites in Kenya. After four years his searches brought him success. They found excellent specimens in the Lauleni deposit in the southern part of Kenya. They decided to name the stones after the Tsavo National Park. The name "tsavorite" itself was put into circulation in 1974 by Henry Platt, who was the president of the jewelry firm Tiffany & Co. Tsavorites began their history on the world jewelry market under that name.
Price per carat
Tsavorites can be confused with emeralds, though tsavorites are a hundred times rarer. The price of high-quality bright-green tsavorites can usually be above $10,000 for one carat. The price of such pieces grows every year, which makes tsavorite one of the best stones for investments and subjects for private collections. The high price of tsavorites is also explained by the fact that, just like spessartine gems, they are not subjected to any kind of beneficiation or synthesis.
At present, tsavorites are mined in very remote areas of Kenya and Tanzania. Stone-mining operations are very difficult, as it is necessary to work manually at great depths. In Madagascar, a tsavorite deposit has been recently discovered in the province of Tulear.
Tsavorite garnet is typically not treated or enhanced in any way, making it a natural and untreated gemstone. It is highly valued for its unique and natural color, and any treatments would compromise its value.
Heat treatment is a common practice for many gemstones, including other garnets, to improve their color. However, Tsavorite garnet is not usually treated with heat, as it is already known for its vibrant green color
Tsavorite in jewelry
Jewelers have been making pieces with tsavorites for only several decades. Now, however, the jewelry pieces graced with this wonderful green stone are more popular than those with emeralds. Buyers are attracted by their rarity, bright green shades of stones along with their wonderful luster, non-infringement, and constant growth of their prices on the market. Tsavorites have become a great investment and a prestigious piece of gemological collections.
A number of foreign jewelry houses produce different models of tsavorite engagement rings. The great rarity of stones makes it difficult to find a pair of identical tsavorites for a set of earrings. That is why only a few manufacturers manufacture earrings adorned with tsavorites. Any tsavorite jewelry piece is an exclusive piece of jewelry that speaks of the wearer's good taste. Collections of rings and earrings with tsavorites from the leading jewelry houses Tiffany & Co., Van Cleef & Arpels and Dior are very popular.
Tsavorite and demantoid garnets may appear similar in their green hues, but they are distinct minerals within the garnet group. Tsavorite is a green variety of grossular garnet, while demantoid is a green variety of andradite garnet. While andradite is softer than grossular, it has a higher refractive index and a higher level of light dispersion.
