The Ma’anshan mine, located near Nanjing & Shanghai, is a lovely turquoise from China. This is Chinese turquoise most like American turquoise from Nevada (Royston) and Arizona (Kingman & Morenci).
Twelve years ago I walked into a booth at the Tucson Rock Gem & Mineral show and saw what looked like nice “blue” Morenci in the rough. It turned out to be Ma’an’shan and I bought as many pounds as I could. This rock was mined in the early 70’s. This turquoise has a beautiful range in color in both blue and green.
Silver Sun has a large selection that looks like Morenci. Twenty plus pounds still remain uncut.
