Vintage 14K White Gold Lab Created Linde Emerald YAG Engagement Ring. Made about 1965, this ring features a center oval faceted colorless stone of Yttrium Aluminum Garnet (YAG), flanked on each side by three round faceted hydrothermal synthetic emeralds made by Linde. This would also make a beautiful right-hand ring.
The ring measures 7 mm wide at the head, which stands 6.6 mm high. Shank tapers to 1.8 mm at the reverse.
The ring is a size 6 and is stamped 14K L* on the inside of the shank.
In very good vintage condition, with very minor surface scratches, and 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.
