Customer Reviews
My 9-year-old bought me the willemite chunk as a birthday present and I love it. I keep it with my yooperlites. I’d love to be able to get other UV-reactive specimens as well. The only trouble was the rock scuffed the barcode from inside and it caused USPS to keep looping it through various postal facilities and I finally was able to get them to deliver it after a month when I called and asked them to physically track it down. Some extra padding around the rocks in the envelope might be helpful for future shipments, but I understand the need for small businesses to keep costs in check.
The piece I received had very few fluorescent crystals. Fortunately, I didn't spend a bunch on it. This is the risk you take when buying off the internet with no photo of exactly what you are receiving.

I lived in New Jersey for the first 41 years of my life & have been to Franklin but never knew there was a mind. Want to have a pice of home with me in NC. Thank you so much & will be buying more ROCKS in the future !!!!
These not only glow nice with long wave, but one of them was also all bright orange calcite under shortwave. A fantastic value!
