Mineral identification and origin are based on collector-applied labels; while we make reasonable efforts to research each lot, Best Estate Services has not independently authenticated or verified the specimen. Chrysocolla specimen lot labeled "Chrysocolla Utah." Includes approximately 30 rough/chunk, small polished/tumbled, and cut specimen pieces in assorted sizes with blue-green, turquoise, green, dark green, gray, tan, cream, brown, and matrix coloration, natural rough surfaces, polished surface variation, and assorted lapidary/display material. Identification and locality are based on the visible collector label/provided lot information; reference sources support chrysocolla generally as a blue-green to green copper-related mineral/mineraloid associated with secondary copper minerals, but not every piece has been individually tested.
