1.72 ct. Thaumasite

Color:  Colorless Clarity:  Eye Clean
Origin:  South Africa Cut:  Rectangular Step
Treatments:  None Measurements:  10.3 x 6.3 mm

By far, the most impressive example of this rare gem species that we have offered.  Thaumasite is a silicate mineral with a somewhat atypical chemical structure - in fact the name of the mineral itself is derived from a Greek origin meaning 'to be surprised' or a wonder.  Typically quite small and usually assymetrical, these are rarely so impressive.  Thaumasite typically forms as a radiating mass of needles and gemmy single crystal pieces are essentially known only from South Africa.  Excellent clarity and absolute precision cutting - all in a superlative size for the species.  With a full GIA cert as well - excellent collectors piece!
