Measurements: 73 x 65 x 26 mm
Description: Citrine quartz crystals with a few pieces of faceted calcite sit on a quartz and chalcedony matrix.
The crystals were originally amethyst, but the specimen was then baked at a high temperature, which turned the colour to citrine.
The only notable damage is to the edges of the specimen. It displays well on a flat surface, all-round. The base of the matrix has been partially trimmed.
