Zircon and Diopside    York River Skarn Zone, near Bancroft, Ontario, Canada.  Ex. Jay Walter collection.  Collected by Jay and Michael Walter, 1992.  This cluster of numerous doubly and singly-terminated zircons measures 3.2 x 2.6 x 2 cm.  The crystals are sitting in green diopside and both sides of the piece show well exposed crystals.  One side has one smaller crystal that appears to have a termination broken.  The crystals are translucent with numerous transparent areas, and very lustrous.  There form is also very nice.  The color ranges from clear, to white, to purple.  Some of the tiny ones have natural, visible, open cracks but they are very stable. 
These are from a small find of this material which produced about a dozen specimens (they were all etched out of calcite) ten of which were thumbnail sized specimens.  This piece and GD-0528 were the finest of all those thumbnail specimens.  They may not look like much in the images but they are, to my knowledge, the finest zircons found at this now closed locality.  This is the best small specimen recovered from the find.  $850
