Description

Higly lustrous and sharply terminated fluorite cubes. All crystals are water-clear with light zoning along edges and intense violet phantom at the corners. White quartz-crystals on matrix are between the fluorites. No significant damage to report, the main crystal has a growth impediment at the corner (no break). I used slightly LED spots for backlit (photo 3 and 4).
