Description

Topaz from Myanmar is not often offered. That's a very nice topaz with a quartz at the base. The topaz is terminated all around, there is only on contact on the lower backside, all other faces are crystallized! The topaz is partly gemmy, shows some bubbles near the base (as you can see on the photos). The quartz is double terminated and perfect crystallized all around. This specimen is more than average regarding quality and aesthetics.
