This listing is for a beautifully made spiderweb turquoise that is blue with black matrix. This stone measures 22 mm by 18 mm and is 4.5 mm deep. This gemstone weighs 16.5 ct. This turquoise is natural and untreated. I'm not sure of the source and believe it to be material from the Kingman mine. I backed this stone with Black Jade. This certainly brings the quality of the stone up a notch.
This stone would be fantastic set in Silver or gold. The shape lends itself to being used in a pendent design.
