Diamond in Kimberlite
Miniature, 4.2 x 2.3 x 1.6 cm
Udachnaya pipe, Daldyn, Sakha Republic, Eastern-Siberian Region, Russia
Ex. Dr. Art Soregaroli
The diamond crystal in legitimate matrix is rather a rarity in the world, due to restrictions on mining and export. These pieces came out in the 1980s, as part of commercial work that Dr. Art Soregaroli was doing in the mining community. The diamond is gemmy and transparent with a subtly complex surface of grooves that makes light reflect brightly, and is absolutely facettable (not just a "reference specimen"). Although it might seem small in a photo, it is 8 x 6 mm in size - not small at all! It has wonderful visual impact because of the clarity and exposed perch on matrix - although it is actually 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 a cheap 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.
