Measurements:
110
x 66 x 40 mm Description: Two double terminated amethyst / smoky quartz crystals, together with bits of squartz and calcite, sit on a basalt matrix. This has been trimmed on three sides, so the specimen can display well on a flat surface, in three different positions. Both crystals have a small, slightly raised pattern (almost droplet form) on their main termination facets, which is slightly dull (possibly chalcedony coated). Near the base of the secondary terminations of the crystals are a few small quartz crystals with numerous reddish hematite specks. The largest
quartz crystal's main termination has only a minute nick, while the
other side of the same crystal has a nick of about 2 mm near the
termination, and a long, narrow nick to its side. The second
crystal has a flaw near its main termination and a fairly large flaw
and bad nick near its lesser termination. To the side of the specimen are the remains of a broken crystal. Weight
