Origin: Golden, BC, Canada Description: Originally, the only known source in the world for this rock was Austria. When it first hit the market, people loved it for the patterns inside. Sadly, over time, the quality that came out of there became poorer and crumbled. This caused the biggest suppliers of rough to stop wanting to buy it.In Golden, British Columbia, a new site was discovered around 2018. It is near a gold mine, and the Pinolith (Pinolite) coming out of there is fantastic quality for cutting as lapidary material. It is soft, like marble- so it cuts quickly. If you're lucky, some even have small pyrite crystals in them.
