Australian Chrysoprase Ring, size 7
Australian Chrysoprase and Sterling silver handcrafted ring.
From Vaughn Nagel
Unlike emerald which owes its green color to the presence of chromium, the color of chrysoprase is due to trace amounts of nickel compounds in the form of very small inclusions. Chrysoprase results from the deep weathering or lateritization of nickeliferous serpentinites or other ultramafic ophiolite rocks.
