Blue calcite with graphite?, New York
A specimen of naturally blue calcite from New York state. There are also some dark shiny looking inclusions which I think are likely to be naturally occurring graphite. The specimen is carefully mounted on a custom wooden base.
1 1/16 inches (2.7 cm) wide, 5/8 inch (1.6 cm) deep, 11/16 inch (1.75 cm) tall.
