One 14 karat white gold Art Deco beautiful black onyx and diamond ring from the 1940s. The ring is in outstanding condition very lightly worn with an intricate filagree design. It is set with one rectangle cut prong set onyx measuring 16.05mm in length and 12.29mm in width. On top the onyx in the center lies a single cut round diamond weighing approximately 0.01cts featuring a color of I and a clarity of SI1. NOTE: the diamond has a small chip in it but it is hard to see without a jewelers loupe and is not affecting the integrity of the ring in anyway. The ring is a finger size 4 and weighs 2.90grams. The shank measures 3.16mm at the shoulders and 1.90mm at the base. The top of the ring measures 17.38mm. Appraisal Value: $900. This ring will be shipped in a vintage suede hand made ring box. These can be purchased separately from my store as well in an array of colors. This information is all 100% accurate and being sold by a GIA graduate gemologist. The ring can be sized or personalized with extra handling time and an extra fee. Please specify in notes at checkout if desired.
