Chalcedony
This was purchased for me by my mom in 2015 on her trip to Taiwan. Specifically this specimen is from Taitung. Pretty good considering she didn't want to bring one of my lights! She just had a feeling it'd fluoresce based on what I showed her before! There aren't any photos of chalcedony even on Mindat. I imagine that's because most of it got turned into jewelry. This was one of the specimens that were being sold along with the jewelry it was made from. Collected by locals that claim that there's not that much of this material left.
