We were so lucky to come across these trapiche amethysts at the Denver Gem Show!
Trapiche minerals are those that form in symmetric crystals such as quartz with a radiating star of inclusions between areas of growth. They're pretty rare since the geological conditions necessary to create these them are uncommon, and we still don't know exactly how, when and why they are made. They've only been discovered fairly recently, and these are from a new mine in Brazil that is currently closed for at least a year while they drum up the investment to drill further.
The color on these amethysts is AMAZING. They're super-gemmy, and the spoke-like patterns you see are just stunning. Amethyst is a type of quartz, so you're seeing the six-sided growth pattern, accentuated by the way these were cut and polished. This one is has great markings and striping on it.
We have several of these generators in stock. This one is 69g and is about 3" x 7/8".
