An interesting corundum specimen where the crystals are mostly blue (sapphire) but have red zones(ruby). The corundum crystals are lustrous and all are terminated with varying amounts of intergrowth with the mica schist matrix. Nice triangular growth hillocks on the terminations. Can be stood up nicely for display. T
