I'm used to mangano calcite beads being uv reactive. These were not. In photo, mangano calcite beads at left were mine from another vendor. The ones on the right are the ones from PanadaHall, and only glow as white would under black light. They should be dark coral.
I contacted customer service and shared my concerns. They basically gave me the runaround, asking for proof, which I provided, and then asked again. They just insisted that they are pink mangano calcite beads. It IS possible that they are calcite, but of such low quality that they don't glow. Either way, they weren't a good product, they didn't refund my money and didn't care.
