38.90ct Its is very rare to find a Oval Parti Sapphire of this size unheated - unheated and not filled, the stone is from a small family mine on the border of Tanzania and Kenya i bought the rough years ago and cut it last year, the stone is Excellent cut and 2-3As in grade a very rare size stone, very few people will be lucky enough to own this museum collector grade stone, i can make a ring after purchase, mail me for a price. This wonderful large stone with lovely faceting would be a valuable investment, large untouched sapphires of this quality and above are so hard to come across, i think you will be very happy to own a stone normally that goes to wealthy serious collectors and connoisseurs of rare and exotic gemstone, there is one of these stones from the same small family mine in a gemstone museum they catalogue all unusual and rare stones in Africa, all stone will be sent via FedEx regardless of post status below. I have tried my best to show the sapphire real view as in the first photo, you will also see a very enlarged photo that shows the bad good and in this case just how unusual the sapphire is, also a small video always gives the best reality. Offers of between 40 - 80 thousand will be taken into serious consideration and some were between might be accepted.
