INTRODUCTION TO TASVORITE STONE
Tsavorite is related to the garnet group species’ grossularite. Since, we know there are generally six types of garnet group stones almandite, pyrope, andradite, spessartite, and grossularite.
The garnet family stones have identical crystal structure; however, the chemical composition of the two stones of the garnet family may not be identical. Garnet stones are probably the most expensive and popular gemstones in the gemstone market.
Coming back to Tsavrorite stone it is the most mesmerizing and expensive gemstone among all garnet stones. Ideally, the stone Tsavorite encloses the green color due to the presence of a trace amount of chromium.
History of Tsavorite Gemstone:
The footprints of the exploration or discovery lie back in 1967 when prominent gemologist DR. Campbell Bridge discovered first tsavorite gemstone in the cliffs of Tanzania near in a village called lemsukho.
The intense green color of tasvorite stone impressed him so much so that he determined to introduce this stone into the market.
Thus, he displayed a piece of tasvorite to gem dealers who really appreciated this stone. However, the government of Tanzania denied the proposal to export this stone outside the border of their country. Nevertheless, Dr. Bridge did not lose hope and extensively examined other possibilities to discover this stone.
Keeping that purpose in his mind, he pondered that the deposit of this stone would not be confined to a specific region albeit it might be possible that the deposit belt of tsavorite lies beyond the boundaries of Tanzania.
Consequently, his endeavor brought him results when he found the other country Kenya, where this stone was stored in abundance quantity. Fortunately, this time he also gained permission from the government to export the valuable stone tsavorite.
In spite of the approval to export this stone obtained actual recognition or identification in 1974 when Tiffany and co stirred the effective marketing campaign to spread awareness about this stone around the world.
Origin of Tsavorite Stone
The name Tsavorite was suggested by Tiffany &Co President Sir Henry Platt in the account of Tsavo East national park in Kenya. The tsavorite stone is not only traced in Tanzania despite Tanzania it is also mined from Tulear and Madagascar. As of now, these are only the major sources to acquire Tsavorite stone.
Physical Composition of Tsavorite Stone
The tsavorite gemstone is ideally a composition of calcium aluminum silicate. Generally, this stone is a mixture of grossularite garnet. The tsavorite stone reflects the delicate green color due to the presence of traces of chromium in the stone that bestows this stone distinct color.
The diversity of its color and rarity has altogether worked in favor of this stone by developing huge curiosity and excitement about this stone in the gem market.
The tsavorite stone is spotted in smaller size largely. As per the estimation of miners that 85 percent of the stone which is mined yields below one carat. Moreover, 10 percent of stone yields above 1 carat and 2.5% stone carries over 2 carat weights. And 1% carries over 3 carat weight.
Hence, these figures depict that it is hard to find a large tsavorite stone. To date, this stone is mined from only two, three significant countries Tanzania, Africa and Madagascar.
Points to Consider while buying Tsavorite Stone
While buying this stone the color of the stone should be examined carefully. A tsavorite stone yellowish green or bluish green like an emerald stone is the identification of natural tasvorite stone. The stone which possesses dark green color should be avoided since it can be a peridot stone.
