Measurements: 40 x 19 x 11 mm
Description: Two double terminated quartz crystals are fused together, and in the one's termination a small double terminated quartz crystal is wedged, with one of its terminations ending in its host crystal. So perhaps, technically speaking, this small crystal is not double terminated (?).
One of the crystals has several very minute inclusions of possibly epidote or chlorite, mostly just underneath the surface (strong magnification needed). A small rainbow can be seen when tilted in light, in both crystals.
The specimen appears to have no damage.
