Savrolite belongs to the calcium aluminosilicate, the chemical name is chromium vanadium calcium aluminum garnet, because it contains trace amounts of chromium and vanadium elements, the color of emerald green is lovely, although it belongs to the late discovery of the garnet family, but with its own strength to leap to become the most valuable and potential gemstone, especially in terms of color, high-quality tsavorite can be comparable to the color of emeralds, and in terms of clarity performance, it is impossible not to be sought after.

The origin of the name
In 1967, Campbell R. Bridges, a British geologist and former president of the International ICA, was exploring near the village of Komolo on TheLelatema Mountains in northeastern Tanzania when he stumbled upon a nodule-like mineral with an earthy yellow inner-clad green gemstone that had been analyzed and confirmed to be a "calcium-aluminum garnet" in the garnet family. However, due to restrictions imposed by the Tanzanian government, hopes for the development of commercial mining in the area have been dashed. Bridges did not give up, he continued to explore the surrounding geologically similar areas, and finally, on the border between Kenya and Tanzania, near kenya's Tsavo National Park, a second deposit with mining value was discovered. Bridges then acquired mining rights in four mining sites in Kenya.
Tiffany was delighted with the new treasure, so he gave this clear bright green gem a name that resembled that of a medieval poet: "Tsavorite", and whenever he recited this name, he could not help but think of the beautiful green gauze skirts of the renaissance painters or the handsome poets with melancholy eyes. In fact, "Schauffre" is not a beautiful stage name that Tiffany specially invented to package stars, but it is precisely the name of its birthplace: Schaffle National Park, which comes from the local vernacular with a rather emotional meaning: follow me. With its ancestral roots in Africa, it quickly became the most "wild and rebellious romantic" gemstone in the jewelry market.

Gemstone characteristics
Compared with emerald and jadeite, their Morse hardness is 7 to 8, 7 to 8, 6.5 to 7, the first two are similar in hardness, jadeite is slightly lower, but the toughness of jadeite is higher than the first two. The high hardness makes the gem less susceptible to scratching by the Sio2 dust in the air, keeping the gemstone jewelry as new as ever. The refractive index is 1.75, 1.58, 1.62 (aggregate), and the dispersion values are 0.028, 0.014, and none. Gems with high refractive index are prone to total internal reflection when processed into faceted gemstones, and the fire color of gemstones is strong. The fire of the gemstone with a large dispersion value has a variety of rainbows, which are indicators of the excellent nature of the gemstone. From the above physical properties, it can be seen that the refractive index and dispersion value of tsavorite are higher than those of emerald and jadeite, and have excellent gem characteristics.
Tsavorite has fewer inclusions than emeralds and is cleaner in crystals. At present, there is no optimal treatment of tsavorite, but oil injection of emeralds is a common phenomenon. In terms of color, tsavorite is no different from emerald, and green emeralds are difficult to achieve their brilliant green. In short, from the comprehensive analysis of color brilliance, physical optical characteristics, crystal cleanliness, etc., the gemological properties of tsavorite are the most excellent.

value
1. The mining of tsavorite is extremely difficult
Rarity is always the golden rule of high gem prices. The mining of tsavorite is very difficult, it is necessary to be familiar with the geological structure, the action is rapid, because the tsavorite appears in the cracks of the rock, and the rock cracks often disappear suddenly in the process of mining, only by breaking these stones, we can see the beautiful and lovely green.
2, Tsavray stone itself has superior conditions
What makes many colored gemstones envious and hateful is the "three highs" possessed by tsavorite. First of all, the high brightness, which stems from its innate extremely high refractive index, which from time to time emits a strong fire; The famous high purity allows it to leave the emerald family's elder emerald far behind, and the very few impurities exude an aura; The high saturation of the intense color is another sharp tool of tsavorite, and what jewelry lover can resist its charm of such high quality?
3. Tsavray Stone has repeatedly achieved good results in auctions
This precious treasure is destined not to be buried, and its brilliance will not only not be hidden, but also sweep through the auction market in recent years. In 2011, Sotheby's sold a 10.76 ct tsavourite ring for 460,000 RMB; In 2015, a 7.65 heart-shaped Tsavray pendant was sold for 420,000 RMB. It can be said that tsavorite is the "potential stock" among colored gemstones.
Today, it is the most popular green gemstone in the global market besides emeralds, and with its beauty and reasonable publicity, it is increasingly recognized by jewelers and loved by consumers.
