Aquamarine C: crystal (South Africa)

'C' grade double-terminated crystal with second bridging crystal. Six complete sides, however sides and faces have traces of white feldspar /albite groundmass over their surface, which continues as inclusions within the body of the crystals as well. Colour is a nice pale sea-green, and the clarity is good where not obscured by inclusions.
Size: 4.25 x 1 x .5 cm 47 carats
