Description: A
stunning two-sided display specimen with the one side having two
azurite crystals up to 7 mm long, on a colourful matrix of malachite
and (?)duftite. The second side is pretty much the same as the main
side, but without the larger azurite crystals.
The
only damage appears to be a few very minute nicks to the two larger
azurite crystals.
