<dd>A beautiful cluster of 3 intergrown crystals, all with perfect terminations. The whole cluster is highly translucent and actually also "gemmy" in the literal sense; and glows when backlit. Complete all around save only a very slight small contact on the back. A large, dramatic, full thumbnail specimen</dd></dl></dd></dl>
