Item Description

This is a classic display specimen from one of the most storied and well known districts in Colorado. The pegmatites around the Lake George area of Colorado have produced what I think nearly all collectors and dealers consider to be the finest Amazonite specimens from the standpoint of superb color, top quality, wonderful display specimens and excellent associations. This cabinet specimen features sharp, well-formed, prismatic, beautiful blue-green color Amazonite crystals very minor Smoky Quartz. The Amazonite crystals have a "striped" appearance, with a deposition of a lighter colored (lead-free) Microcline on certain faces. A beautiful overall piece, showy and damage free as far as I can see with the naked eye. It's important to note that this piece is COMPLETELY UN-REPAIRED, unlike a large number of the specimens found in this area today. This specimen was in the collection of Richard ("Rich") A. Kosnar (1946-2007), the well-known mineral dealer and collector from Colorado. Specimen #103. Rich actually moved to Colorado from New Jersey in 1970 specifically to mine Amazonite specimens. It was shortly after he arrived in Colorado that he met his future partner, Clarence Coil, with whom he collected some of the finest Amazonite and Smoky Quartz specimens ever found in Colorado. Clarence actually collected this piece personally in 1936, and it has remained in the collection of Rich Kosnar (and later his family) since the 1970s.
