A fine, well crystalized old Danburite from Russell, New York. A classic of the Historic St. Lawrence County region, this specimen is from the late Ingeborg Burggraf collection. Several zones on the matrix host dense clusters of Danburite crystals with several habits, most being transparent to translucent and fairly glassy. The crystals reach over 1.3 CM though the majority are smaller. Uncommon on the market, the clear type like this are usually somewhat smaller in size this is well above average for quality.
