Turquoise Gemstone 925 Silver Plated Handmade Stud Earrings This stone comes from as far as the winter corners of Nova Scotia to the parched dunes of Namibia, bringing a low humming vibration. TURQUOISE of a greener hue is also found in the mountainous lands of Tibet. It’s been discovered in the vast and open Mojave desert in California and other areas of the USA where Apache mines invited the watery stone to flow out of the earth and into people’s hands.
