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.
