Description: The main crystal has interesting extra crystal facets and is supported by another crystal that meets at an angle of about 45º. The specimen displays very well.
The main crystal has two phantoms. The 1st generation crystal is coated with an olive green coating (unknown mineral), while the 2nd generation quartz crystal is coated with a yellowish-brown and black coating, presumably hematite.
The surface of the specimen has a strange 'pitted' effect, with a reddish-brown coating of iron oxode. The bottom of the specimen is covered with minute quartz crystals.
Apart from a few minute nicks, the main crystal is undamaged. There is some damage to the lower end of the specimen.
