Item Description

Amazonite is a well-known blue-green variety of Microcline Feldspar, and some of the most iconic examples are those from the various granitic pegmatites around the Lake George / Crystal Peak area of central Colorado. These fine quality specimens truly stand out with their superior color and quality forming wonderful display specimens sometimes with excellent associations. Here we have a gorgeous specimen of this classic material featuring excellent, sharp, rather lustrous, well-formed, vivid blue-green color prismatic Amazonite crystals which show unusual areas of white color zoning. Typically, Amazonite crystals are fairly uniform in color, so to find a piece like this with notable variations in color is uncommon. No damage, complete all around. I must also point out that this specimen is un-repaired, which is noteworthy as a lot of Amazonites you'll see from contemporary mining will have many repairs (sometimes dozens of repairs). Keep in mind that the best Amazonite specimens (especially UN-repaired pieces with top color) sell for big money these days, and considering how few un-repaired top quality specimens are found each year, this one would make a great addition to any collection. This piece is from the collection of Brian Kosnar, and it was originally collected nearly 50 years ago (August 1975) by his father Richard Kosnar. Rich found some of the finest color Amazonite specimens from Colorado extant. Don't miss out on this fantastic Colorado classic.
