Measurements: 77 x 67 x 58 mm
Description: A group of amethyst quartz crystals (of which some double terminated) with interesting growth patterns, sits on a basalt matrix, partly covered with minute (?)calcite crystals.
The quartz crystal group has one nick of about 6 mm long on one of the smaller crystals, and another small crystal has a very minute nick (hardly visible with the naked eye) to its termination tip. The calcite crystals have nicks to the edges of the specimen.
This is a
beautiful specimen that displays well on a flat surface in more than
one position. The matrix has been trimmed on three sides, to
display better.
