This Perfect Natural mined AAAA+ Tanzanite comes from the D,Block mines in Merlerni Arussa Tanzania. Discovered in 1967 the mines are vertually empty of top quality Tanzanite. A beautiful IF Flawless stone, weighing a superb 5.30ct and measuring 10.32 x 8.84 x 6.81mm. The colour is a Perfect Kashmir Deep Blue Violet with excellent neon saturation and red flashes. Stones of this size and quality are very rare and now is the time to buy, as Tanzite will be no longer mined within the next Ten years. The prices are increasing rapidly making Gems like this not only a stunning one off jewellery peice, but a excellent sound investment as well. This stone bought from a high street jeweller would cost three times the amount of the start price that is if and i mean a very big IF, they could get this size and quality. i very much doubt it This beautiful one off peice comes fully certificated and pictured with a top world renowned labratory certificate from the G.I.A.  Gemological Institute of America. ( not a worthless apraisal cert invented by some?)  sj
