I hand cut this remarkable freeform kite shaped cabochon which measures 43x31mm and is 6mm thick with polished sides and back. Black druzy quartz of this quality is very desirable and VERY hard to come by! Druzy (also spelled drusy or druse) means a coating of small crystals on a rock surface, often a cavity or a vug in a geode. Not all druzy is quartz, but this definitely is.
When I was in Tucson in February I found one major dealer of Brazilian minerals who had ONE table with druzy quartz specimens on it and I bought almost all of it! I went back in 2015 and bought all they had, which was a limited supply! Both years it was my best score of the show. In having gone to Tucson or Quartzite over 12 times in the past 25 years and countless rock and gem shows regionally, I can tell you that this is special stuff! I asked the dealer if it was irradiated to make it black and they assured me that it was naturally black. They called it "black amethyst" and if one looks under bright enough light at a certain angle, on some of it there is a detectable purple hue. Most of the cabs I cut out of this have no matrix on the back. If there is matrix on the back, it's a simple, ugly grey aggregate and I'm unsure of what it is officially composed.

For those interested in the metaphysical properties of stones, this would have the same properties as quartz and as amethyst. You can look that info up on the internet.
