Description

This tourmaline specimen, either uvite or dravite varitey, was collected by and acquired from John Betts. On his website, Betts writes, “Both dravite and uvite tourmalines are found in NYC. Most are generically referred to as brown tourmaline, because exact species identification requires testing and a collector cannot rely on morphology to determine the species. Dravite crystals have been confirmed from the Inwood marble.” 

The label that accompanied the piece reads "uvite and graphite", the graphite presumably being inclusions in the matrix material.
