Goethite, Hematite, Siderite, Quartz (Var: Smoky Quartz)
Description
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.

How this data is collected: Our system continuously monitors mineral listings from authorized dealer partners across the internet. We have explicit permission from all dealers whose listings we track - any dealers who have not provided specific and explicit authorization are NOT listed and NOT tracked by our system. When a previously available listing is marked as sold or removed from sale, we record this as a completed transaction. While we cannot guarantee the exact final sale price (as negotiations may occur), this data represents publicly listed prices for specimens that have transitioned from "for sale" to "sold" status. This provides valuable market insights based on observable listing behavior patterns.
