Quartz with Calcite and Spessartine on Matrix

Two uncommonly large twinned quartz crystals on albite feldspar matrix, shading from milky at the base to smoky in the middle to clear at the termination points. A small but richly colored spessartine crystal is hidden on the reverse. A particularly fine and rare specimen, given the difficulty of preserving such large crystals when removing them from the pegmatite wall.
