An impressive and unusual large cabinet amethyst and smoky quartz specimen from recent finds at Irai, Brazil. Gemmy and lustrous, vivid purple, amethyst crystal rosettes are richly and very attractively scattered on a 3-dimensional, flute-like matrix of glassy and gemmy, smoky quartz crystals. The amethyst and smoky quartz rest on a thin crust of intergrown quartz crystal rosettes. The amethyst and smoky quartz crystals have excellent luster on this piece, which has many small "caves" and even a hard-to-see, 4.7 cm long, natural arch of amethyst and smoky quartz lower on the side of one face.
