| Description |
This is a fine, sizable individual "Herkimer diamond"* quartz with dark carbon inclusions. The main crystal at nearly 3 centimeters wide and 7 cm long is large and distinctive, with a fine, although slightly altered termination on one side, and an attachment point on the other end which appears partially rehealed. A smaller, clearer crystal is aesthetically crossing the main crystal as a penetration twin, crossing at about a 50 degree angle, with a fine termination. A second, even smaller, parallel growth twin of quartz sits between the two main crystals, adding a unique visual aspect, particularly looking down the c-axis. Being a slightly rougher sample, this piece presents an accessible, aesthetic and high-quality piece for a locality collector or quartz enthusiast.
*This is NOT a diamond, it is quartz. |
