Calcite with Fluorite (gemmy crystals!) (ex Dr. Stephen Smale Collection)

Item Description

A classic specimen of the well-known Xianghualing material featuring several superb quality, very sharp, lustrous, notably gemmy, colorless, compressed hexagonal crystals measuring up to 2.1 cm associated with virtually water clear, soft green cubes of Fluorite measuring up to 1.6 cm on edge on matrix. It's important to stress that the Calcite crystals on this specimen are rather gemmy, as most we've seen over the years are somewhat milky and translucent. The piece was DIFFICULT to photograph, but it's incredibly three-dimensional and displays wonderfully. Better in person. Excellent condition all around with only a few minor rough spots that I can see with the naked eye. Originally priced in our inventory at $700. Ex Dr. Stephen Smale Collection.
