The most classic old US locality for the species is from the silver and gold mines in Cripple Creek, Colorado (late 1800s and early 1900s). Most available specimens come from old collections and museum deaccessions. This is a very rich specimen for sheer quantity of platy calaverite crystals embedded in the matrix, showing brilliant metallic flashes from all sides of the specimen. Many of the embedded crystals reach 1 cm, some clusters more so. This came from Harvard via exchange to Phil Scalisi to George Elling, though no label accompanies the piece.\u003C\u002Fdd>\u003C\u002Fdl>\u003C\u002Fdd>\u003C\u002Fdl>",400,339,{"id":245,"source_url":246,"license_code":247,"credit_html":248,"title":249,"description":250,"author":251,"original_width":252,"original_height":253},37793,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=6361689","CC BY-SA 4.0","Didier Descouens, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=6361689\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Calaverite.jpg","\u003Ca href=\"https:\u002F\u002Fen.wikipedia.org\u002Fwiki\u002FCalaverite\" class=\"extiw\" title=\"en:Calaverite\">Calaverite\u003C\u002Fa>  - Creeple Creek – Colorado (USA)  (2x1cm)","Didier Descouens",4788,3266,{"id":255,"source_url":256,"license_code":229,"credit_html":257,"title":258,"description":259,"author":233,"original_width":260,"original_height":242},4333,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=10461211","Robert M.

Telluride species from this area are highly sought after by collectors, and it is well justified as some superb examples are known from the various mines in the area. This specimen hosts a few small, excellent quality sharp, lustrous, tabular, striated, monoclinic crystals of the rare Gold Telluride, Calaverite which have a bronzy hue. The crystals have a classic association (for this mine) of purple Fluorite and are sitting against grey Quartz matrix on matrix. The largest Calaverite crystal measures a few mm in length which is typical for the species and the locality, but an association with purple Fluorite is not typical. These specimens are very difficult to obtain, and considering that the majority of them were mined over 100 years ago, the only source for specimens is old collections. Ex.
