Turquoise & Diamond EarringsOne of a kind, Kingman pale blue with black matrix turquoise encased in palladium accented with 1. 75 mm GH VS diamond melee. These have a nice weight due the palladium which happens to counteract the featherlight nature of the turquoise slab. Kingman Turquoise : I have a rather extensive collection of Kingman turquoise from 1960 in a variety of colorways and of which the slab for these earrings was cut directly from the boulder for this application.
