Calcite (iron-bearing twin) on matrix (ex Dr. Stephen Smale Collection)

Item Description

A beautiful near full cabinet display specimen featuring a predominant sharp, compressed twinned crystal of translucent Calcite which grades in color variation from nearly colorless to a reddish-orange hue (iron included) on additional Calcite crystal matrix. A second compressed un-twinned Calcite is also free-standing on the piece, but it's the larger twin (which measures 4.7 cm across) that draws the eye. Both of the big crystals are damage free, and the piece is expertly trimmed so there are only a few small imperfections along the periphery where it was removed from pocket wall. A very attractive and eye-catching specimen of this find, where the locality in Hubei Province was not divulged for some time. BETTER IN PERSON! Valued at $1,800 for quality and wonderful form / aesthetics. Ex Dr. Steven Smale Collection.
