This is a great specimen from one of the most storied and well known districts in Colorado. The pegmatites near the Lake George area of Colorado have produced what most 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 particular specimen has no Amazonite, but it is a nice display piece featuring sharp, lustrous, golden-black "needles" of Goethite and metallic grey pseudmorphs of Hematite after Siderite sitting atop a translucent Smoky Quartz crystal. According to Rich Kosnar, Hematite pseudomorphs on Goethite were very rare, and this specimen was the only piece from this claim to show them associated in this manner. This specimen was collected nearly 30 years ago (August of 1980), when Richard Kosnar found some of the finest color Amazonite from Colorado extant. Ex. Richard Kosnar Collection.
