Beryl Var. Aquamarine on Quartz (ex Nelson Coll.)
A very unusually zoned aquamarine crystal with an exceptional termination and a cloudy core that forms a hexagonal outline within the crystal. As you can see, the beryl is cloudy up until the termination, drawing a very distinct line and then becomes of faceting grade. This wonderful crystal sits on a matrix of quartz, feldspar and a smaller beryl on one side. Super!
