Description

This asthetic specimen has resided in my own collection for the past 15 yrs but it is now time for someone else to appreciate it. The vug is lined with sparkling quartz micro-crystals with an underlying green mineral (I believe this to be saponite). Gyrolite balls are liberally scattered around. The floor of the vug is flat with a thicker layer of the quartz, looking like a carpet of snow. Finally on top of this carpet sits a puff-ball of delicate radiating okenite crystals. A little Aladdin's cave of crystallisation. Heavy specimen, shipping Europe $17, US $30
