Very rich specimen with tens of perfectly terminated, green coloured crystals of zincolivenite with very good lustre, richly covering a quartzite matrix. Such specimens were previously labelled as cuprian adamite, but recent studies (i.e., Southwood et al, 2020) have shown that are indeed zincolivenite.
