I bought this specimen in 2023 from the Tenke Mine which is a relatively new mine. There is a single cobaltoan calcite crystals deposited on a country rock matrix and surrounded by pale blue green plancheite. Just behind the crystals of cobaltoan calcite there is a recess with a botryoidal mass of light olive green kolwezite. The cobaltoan calcite measure 1.5cm coming off the matrix with good lustre and gem quality. The colour is bright pink..
