“6.4 x 4.2 x 4.2 cm. A fine upright cluster of highly lustrous, jet-black aegirine crystals with etched terminations. This is an excellent, complete-all-around specimen. One side is richly sprinkled with tan zircons and off-white feldspar crystals and the other side is very nicely accented by a cluster of feldspar crystals. The vertical aegirines are all pristine.
