Dreamlike slightly smoky large rock crystal-smoky quartz triplet crystal

A large, slightly smoky rock crystal-smoky quartz triple crystal from Zimbabwe, 58 cm high. Three twinned quartz columns with flowing transitions between clear and slightly smoky quartz-colored areas.

Rock crystal and smoky quartz are varieties of quartz with different trace element configurations. A change in coloring documents oscillating solution chemistry during crystallization. Such mixed forms are classified in the collector's trade as color-zoned smoky quartz.

Triplets are a rare twinning variant in which three crystals share their growth axes according to crystallographic laws. For a specimen of this size, the twinning is a crystallographic sensation.

Zimbabwe supplies clear quartz material from pegmatite deposits in the Karoo Basin extension. Material from this region is among the valuable African collector's sources for clear rock crystal triplets.
