Item Description

Mineral specimens of ANY species are very rare from this pegmatite, renowned for huge beryl, spodumene and feldspar crystals. This very showy combination piece features a really pretty fan spray of pearlescent, nearly transparent, yellow-green muscovite plates flanked by rare, lustrous, euhedral, black, columbite-tantalite crystals. Probably older material. Very, very seldom on the market in this combination quality! Ex Josef Vajdak Collection.
