Aegirine (ex David Burgess Collection)

Item Description

I think it's safe to say that the finest Aegirine crystals have been found at Mount Malosa in Malawi. Here we have a wonderful single crystal of this classic material in the form of a sharp, highly lustrous, deep greenish-black prism of Aegirine. The crystal is actually doubly-terminated, as you can see the bottom is recrystallized, but there is a separation mark on the prism where another Aegirine crystal grew. The main termination is highlighted by a single gemmy Quartz crystal flaring out of the top. For a Pyroxene, this is incredibly lustrous and sharp for what it is. From the worldwide collection of David Burgess (1951-2016). David was a prolific species collector from Newington, Connecticut, and the namesake for the extremely rare cobalt arsenate species Burgessite, which he discovered.
