Made about 1965, this ring features a center oval cabochon of hydrothermal synthetic bluish green emerald made by Linde, and two accent stones of yttrium aluminum garnet, a diamond simulant made by the same firm. The ring has a gorgeous rope bezel surrounding the prong set center stone and a double rope twist shank.
The ring measures 16.4 mm wide at the head, which stands 9.3 mm high. Shank tapers to 2.65 mm at the reverse.
The ring is a size 7 and is stamped 14K on the inside of the shank.
In very good vintage condition, with very minor surface scratches no damage of any sort noted.
We recently obtained a collection of rings from the estate of a long-term Union Carbide employee. This ring if from that purchase. The Union Carbide company created a number of synthetic stones in the period from 1940 -1980. Among their production were Linde Star Sapphires, Linde Star Rubies, Linde Hydrothermal Emeralds, Lab-Created Amethysts, and Synthetic Yttrium Aluminum Garnets (a diamond substitute). Union Carbide employees were able to purchase jewelry containing these stones through the company and this gentleman bought his wife dozens of rings over the decades.
