Description: Diamond Locality: Udachnaya Mine, Yakutia, Siberia, Russia Size: miniature, 3.7 x 2.1 x 1.2 cm Diamond on Matrix A Superb gem quality and SHARP diamond crystal in matrix from Russia . The crysatl is a single octohedron with intricately stepped faces. The diamond has been estimated to be just over 1.5 carats. The diamond is gemmy and read-through, absolutely facetable. It measures 5 mm on edge. Although it might seem small, it has wonderful visual impact because of the clarity and perch on matrix. Embedded perhaps 50% in the matrix, so you know it is real. What is more, you can look right through the diamond to the matrix underneath! Around the diamond is a thin white layer you sometimes see, which indicates not glue but rather an alteration in the surrounding rock due to the chemical heat of formation of the crystal and is a good indication of its origins as natural. 3.7 x 2.1 x 1.2 cm
