7.5 x 5.0 x 4.7 cm. Crusts of scintillating apophyllite microcrystals partially cover the front and back and terminations of three, gem-like, sceptered calcite crystals from the Verchniy Mine at Dal’negorsk. The water-clear, modified rhombohedral calcite scepters are beautifully striated and are perched on translucent calcite scalenohedrons. Lustrous, black ilvaite is visible at the base of the specimen, just above the bit of matrix. An excellent and uncommon combination specimen from the locale and the Ryan Bowling Collection. This fine piece dates to the early-mid 1990s and is of a style available today only in recycled collections.
