An extremely gemmy Smoky Quartz crystal with a very aesthetic spray of the mineral Riebeckite included within. The Riebeckite that is included in this crystal is hair-like, very distinct and quite easily seen, unlike most riebeckite included Quartz crystals which typically have a jumble of Riebeckite crystals in them.
specimen size = 7 x 2.5 x 1.5 cm.
