Quartz   2nd Sovietsky Mine, Dal'negorsk, Primorsky Kray, Russia. Ex. Harold L. Dibble collection. FIGURED SPECIMEN from the book, Quartz: An Introduction to Crystalline Quartz, page 10, by Harold Dibble. This is the nicest example of this fine beta-form quartz that I have seen outside a museum. The large plate measures 15.5 x 15.2 x 4.2 cm. The crystals are both the recognizable light green and white. Most of the smaller crystals are clear. The largest crystals are up to 3 cm each. One crystal near the center of one face (the one most individuals would consider the front and the side that was photographed in Harold's book) has a chip. Other than this the piece is in amazing shape on both sides and even the edges. Minor edge contact on one side. Great example of this uncommon material.  On sale for $2,100
