From a famous discovery, which produced a low number of specimen crystalized in a special habit - spinel-law twinning. The colour is light blue in the center, and lavender in the outer zones. Along the edges you can see darker zoning, which tend to very deep violet. The crystal is resting on a small white plate of feldspat. It is complete and well formed all around. The saturation is better than average and also quality and clarity are remarkable for this find. The composition of the two freestanding crystals is very aesthetic! No significant damages to report.
