Size: 73 x 35 x 18 mm
Weight: 70 GramsChrysocolla
Bacan stone is known as the scientific term Chrysocolla in chalcedony or translated into Indonesian, namely krisokola quartz. Bacan stones come from Kasiruta Island which is reached as far as 3-4 hours from Bacan Island, South Halmahera, Maluku. Because of the stunning appearance and color of the stones, Bacan stones are often sought after by people as jewelryThe identical green, bluish, and blackish colored Bacan / chrysocole stones are caused by the process of changing the mineral element copper (Au) porphyry. The formation of porphyry deposits is related to hydrothermal processes. These deposits are carried by a solution of high temperature water and deposited under the surface. These porphyry deposits usually form Au metal deposits and are associated with the stockwork system. Stockwork is a condition where minerals accumulate above igneous intrusion and form a complex system of multiple and random veins. The location of these veins causes porphyry ore deposits to form. Usually it is in these deposits that chrysocole can form simultaneously.# DELIVERY
