Description

Large and rich specimen with excellent rare combination of minerals. It seems like conichalcite is the dominant mineral that covers/replaces the cuprite crystals and that is unique. On top of some conichalcite psm cuprite crystals, there are gemmy and lustrous crystals of adamite. As a bonus, several bursts of olivenite crystals are found in various areas of the piece. A party of green copper minerals, so interesting and unique.
