A superb gem quality and SHARP diamond crystal in matrix from Russia - this is a rare specimen of EXTREMELY fine quality. The diamond has been estimated to be just over 1.5 carats. The diamond is gemmy and read-through, absolutely facetable. It measures just over 5 mm on edge and slightly more across. Although it might seem small, it has wonderful visual impact because of the clarity and perch on matrix. Embedded perhaps 40% in the matrix, so you know it is real. What is more, you can look right through the diamond to the matrix underneath! There is a very thin rind of white around the diamond, indicative of the chemical heat of formation of the crystal and is a good indication of its origins as natural. 4.2 x 4 x 2.4 cm
