Her you get the a ショール (鉄電気石) (Schorl) / ルベライト (Rubellite) 結晶 crystal from Molo with the typical changeover from the prismatic to the botryoidal growth. In the middle you also can see the remaining prismatic trigonal core, which was maintained throughout the botryoidal growth. A great piece with fine luster and no damages !!
