No. C 72 - $ 2200.00

MICROCLINE (variety "Amazonite" ) on Albite (variety "Cleavelandite")

Locality: R. A. Kosnar Claim, Lake George area, Park County, Colorado

Specimen Size: 5.0 x 4.8 x 3.1 cm (miniature)

Collected: December 27, 1975.

I've seen as many Amazonite specimens as any collector or dealer in Colorado. This is the only piece that I've ever seen like this. Two superb, sharp, lustrous, deep dark blue-green color crystals aesthetically growing together and forming a "bridge" over a mound of Cleavelandite blades. The quality and deep dark color of these crystals is fantastic. A very unique specimen.

MICROCLINE (variety "Amazonite" ) on Albite

Locality: R. A. Kosnar Claim, Lake George area, Park County, Colorado

Specimen Size: 3.8 x 3.7 x 2.5 cm (miniature)

I really like this piece simply because I have a genuine appreciation for Amazonites, especially any Amazonite specimen on Albite (var: "Cleavelandite"). This piece exhibits two superb, very sharp, lustrous, dark blue-green color crystals aesthetically perched on Cleavelandite blades. The quality and deep dark color of these crystals is very very good.
