Old stock Ithaca peak Kingman turquoise handmade sterling silver pendant necklace

Genuine old stock Ithaca peak high blue Kingman turquoise cabachon is set in a handmade sterling silver pendant necklace
I cut and polished the cabachon from rough material that came out of the Kingman mine in the 1950's. They didn't get much of this high grade material in the 50's and 60's when in high production from the mine
the turquoise cabachon is 22 x 13 mm and 10 carats
the 1.4 mm sterling silver chain is 20 inches
Comes with black velvet gift box
