This aesthetic and dramatic specimen features two generations of quartz crystal growth. The first generation was comprised of three, milky to colorless, large quartz crystals, to 6.75 cm in length. The second generation consists of gemmy, smoky to citrine colored quartz crystals, to 1.5 cm in length, that have grown like a pincushion over the earlier generation. This is pure and simply, a mesmerizing specimen! We had a Scovil photo taken of this, for use in advertising, which comes included.
