607g Rare Silvery Magnesium Ore Wave Shape Cluster Mineral Specimen
Red Heulandite with Stilbite & Chalcedony in Vug - Jalgaon, Maharashtra, India
Quartz var. Amethyst cast of an elongated Calcite crystal. Artigas Department, Uruguay. The preservation of the Calcite habit is so precise and perfect that it's easy to tell that this was a barrel shaped hexagonal crystal. The Calcite has long since etched away, leaving behind a ghostly shell of itself in the form of a translucent Amethyst cast.
