The Neptune Mine is located in Esmeralda County, Nevada. This is one of the first and only (at the time of this writing) woman-team owned and operated variscite/turquoise mines in the country. Emily Otteson and I (Helen) are excited about this wonderful discovery we made! And on this one we get to tell the boys where to dig! ... Well, sometimes on our other mines too lol! They're good at listening to us because they know we're good at finding the gems ;) ... I think you will love the amazing bright greens with bold black matrix and the light, bright and intricate spiderweb stones this mine produces!
