Strontianite Value, Price, and Jewelry Information
Strontianite is a collector’s oddity, with no spectacular properties to recommend it. Colors are usually pale and there is little fire; in addition, the high birefringence doubles back facets and kills the brilliance of the stone. Cut strontianites are, however, decidedly uncommon and worth pursuing for their scarcity value.
