Beschreibung:

Hayfork Creek, Trinity County Klamath Mountains, California The “Enigma” is a tabular stone that has the rough outline of an equilateral triangle. Grayish brown and semi-translucent to opaque there are microscopic black specks scattered throughout the specimen which contribute to the grayish appearance. The broad surfaces are encrusted with a diamond overgrowth that is fine-grained and regular on one side. On the opposite side, a small area has a similar overgrowth made up primarily of overlapping hummocks rising about 4 mm above the essentially planar surface. Two edges of the triangular stone are cleavage surfaces, indicating that the stone was originally larger. Weighing approximately 17.83 carats and measuring 19.72 x 15.33 x 9.95 mm.
