TSAVORITE FAQs

WHAT IS TSAVORITE?

  • Tsavorite belongs to a category of exclusive gemstones that is totally natural. It is not heated, oiled, fracture-filled or irradiated to enhance color or clarity.
  • It is a green grossularote, the calcium rich member of the Garnet family.
  • It is a calcium aluminum silicate colored by traces of chromium and/ or vanadium oxide. A yellowish hue in the green gem indicates the presence of iron oxide.

WHERE DOES TSAVORITE COME FROM?

  • Tsavorite can be found in both Kenya and Tanzania. (South-Eastern Kenya to North-Eastern Tanzania)

HOW RARE IS TSAVORITE? IS IT A FACT THAT ITS BECOMING RARER?

  • Tsavorite is a rare gemstone since it is mostly found in small and unpredictable deposits.
  • The formation of Tsavorite, which involved heating and folding of rocks millions of years ago, shattered most of the crystals. This is why it is very rare to find Tsavorites above 2 carats and nearly impossible to find any above 5 carats.
  • According to Campbell Bridges, the man who discovered Tsavorite and has devoted over twenty five years to mining the stone, approximately 85% of material mined yields stones under one carat, 10% yield stones above one carat, 2.5% over two, 1% over three. Stones over ten carats comprise about one tenth of one percent of total production.
  • Campbell Bridges says that its at least 1000 times rarer than Emeralds.

IS TSAVORITE A PRECIOUS GEM?

  • Three qualities determine whether a stone is precious. They are its beauty, durability and rarity, with rarity having far greater influence than either beauty or durability. Tsavorite possess all three and is therefore a precious gem.

WHAT IS THE ORIGIN OF TSAVORITE?

  • Tsavorite was discovered in the 1960’s by Campbell Bridges. In 1973, Henry B. Platt, the former president of Tiffany & Co., along with Bridges , named the precious gem after the Tsavo National Park and the Tsavo river.

WHAT IS THE COLOR RANGE OF TSAVORITE?

  • Tsavorite is a very beautiful green which can range from a fresh spring-green through a rich bluish-green to a deep forest-green. The most valuable/desirable hues are pure green or rich forest green or where there is a blue overtone.
  • Tsavorite exhibits a far greater brilliance (its bright and it sparkles) when compared to Emeralds, which can be especially seen when its set with diamonds. If a diamond is set next to Emerald in a ring, you have a brilliant spot followed by a relatively dull spot. Flow of the eye starts and stops. However, when a diamond is followed by Tsavorite, the brilliance is continuous and the eye flows along the band from white to green fire.
  • With Tsavorite, its possible to find small stones that express beautiful shades of green. 

WHAT IS THE COMPOSITION/HARDNESS OF TSAVORITE?

  • Composition: Calcium aluminum silicate
  • Hardness: 7.0 to 7.5 on the Moh’s scale.
  • Tsavorite is rather tough and durable.
  • Tsavorite has a Refractive Index (RI) of 1.74, measured using a refractometer, which measures the amount of light rays that are bent by a mineral. Tsavorite’s higher RI in comparison to that of Emerald (1.57) is one of the reasons for its brilliance.

HOW POPULAR IS TSAVORITE?

  • Tsavorite is becoming increasingly popular. Part of the reason why its not known as well is because of the fact that its overshadowed by Emeralds.

HOW IS TSAVORITE GRADED?

IS IT LIKELY THAT TSAVORITE WILL BE DISCOVERED IN ANY OTHER PART OF THE WORLD?

  • The answer to this question is not entirely clear yet. What can be said is that as of today, Tsavorite is being mined in fine gem quality only in East Africa. That Tsavorite deposits are generally not very large or extensive but some of the known ones are either not well developed or mined beyond a certain point. This is partially because of the fact that the gem does not have World Wide popularity. Once this happens it is presumed that the gem will fetch a fairer price and therefore attract lucrative investors.
