Item Description

The vast area of granitic pegmatites around the Lake George / Crystal Peak area of central Colorado have produced the most iconic specimens of Amazonite in the world. These specimens truly stand out with their superior color, quality, wonderful display specimens and excellent associations. Here we have a gorgeous specimen of this classic material featuring excellent, sharp, well-formed, vivid blue-green color prismatic Amazonite crystals which show unusual white "stripes" along the prism faces. A VERY small percentage of Amazonites feature these "stripes" on the crystals, and when you find them on such richly colored crystals, it's even rarer. 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.
