Description

A really marvellous specimen! This huge freestanding crystal is razor sharp terminated and highly lustrous. It shows light smoky color and wonderful inclusions, resting on a thin shim of matrix, which is partly covered by smaller crystals of sparkling quartz. The specimen is very aesthetic in each angle and photos only give you an idea of the piece - even much better in person!
