Two Green Cap Tourmalines with Quartz, Albite & Muscovite – Shigar Valley, Pakistan Outstanding and highly aesthetic mini-cabinet specimen from the famous Shigar Valley, Pakistan. This remarkably complete specimen features two beautifully developed black tourmaline crystals on the same matrix, displaying excellent natural striations, glossy surfaces and subtle deep green terminations (green caps). The tourmalines are beautifully associated with a perfectly terminated quartz crystal, delicate white albite formations and elegant muscovite blades, creating an exceptionally rich and harmonious mineral combination. A superb example of the mineral diversity of the Shigar pegmatites, bringing together two distinct tourmaline crystals and three associated minerals in a single, remarkably complete and aesthetic mini-cabinet specimen.
