This macle twin is not only stunning, but is also rather thick at 3.5 mm in thickness to have such clarity. It is very clean throughout, with only a few extremely slight carbon inclusions, and you could call it gemmy and literally mean "GEMMY" when you say it.. It has an amazing PRESENCE and is just astonishing to hold in your hand...you really have trouble believing that this is a REAL diamond! The triangular form is unusually equant for a stone of this size, and it "looks" naturally cut. It has, obviously, considerable gem rough value and I am told it should yield about 40% recovery in the form of several large stones and some smaller ones. Bottom Line: this is one of the largest and finest specimen diamonds I have seen for sale on our market, to survive the butchers...er, cutters. It certainly is the biggest diamond of any quality that I have seen for sale on the open market as a specimen in 2 years or so since I last had one of these beasts. In person, it presents as simply an astonishing piece to both collectors and layment alike. MORE CLEAR In PERSON! 9.94 carats: 1.6 x 1.5 x 0.35 cm
