This is an impressive, and probably old, specimen of amethyst form the ancient workings of quartz in Idar-Oberstein, used for centuries for carving and lapidary art. Still today, the world center of the highest end of the lapidary crafts is based in Idar-Oberstein, though stone to work on is now imported from elsewhere. This is a complete and beautiful pocket of amethyst, obviously extracted with care. It has deeply colored crystals to 1cm, huddled within a white agate rind. Ex. Helmut Bruckner Collection.
