Stunning Natural blue violet tanzanite gem. 1.70 carat stone so a good size with a vivid violetish blue colour. This gem has a beautiful colour with excellent clarity. It also has an excellent pear cut to show great shine and colour, lots of sparkle! Some of the tanzanites we currently stock come with IGI India lab cards.While we wouldn't usually use this lab, the stones arrive with these direct from the cutting centre. Obviously the stones have still been fully tested by us to guarantee they are natural tanzanites. Tanzanite is a rare gem which is only found in a small area of only a few kilometres in the Mererani hills near Mount Kilimanjaro in Tanzania. It has not been found anywhere else in the world and the chances of other mines being discovered is very unlikely. A rare single source gemstone which is said to be hundreds of times rarer than diamonds! There are only 4 mines operating here at the moment and supply will not be able to keep up with demand forever. Tanzanite comes out the ground a brownish yellowish colour and requires heat treatment to bring out the bluish violet hues. All blue or violet tanzanite on the market will have been heat treated. Many sellers do not even disclose this treatment because it is so routinely done. All our products are tested by a gemmologist with the following qualifications. Distinction grade in gemmology with the Gemmological association of Great Britain (Gem-A). Accredited jewellery professional (AJP) with the Gemmological institute of America (GIA). Fellow of the Gemmological association of Great Britain (FGA). We only deal in natural, earth mined gemstones. As with all our photos, there is no editing or modifying.
