18 Karat Two-Color Gold, Coral, Turquoise and Diamond Ring

Of bombé form, centering an oval-shaped coral cabochon, within an openwork mounting decorated with turquoise cabochons and rows of diamonds, size 7.

 

In good condition. The gold, particularly on the base of the shank, displays scratches commensurate with wear and the remnants of an indistinguishable assay or maker's mark. The coral is a very slightly orange pink and displays very slight, fine banding under magnification. The turquoise ranges from a light, very slightly greenish blue to a deep greenish blue. The single-cut diamonds are approximately H-J color, VS clarity with some SI examples, weighing a total of approximately .60 carat.
