Laboratory-Grown Spinel 14K Yellow Gold Mounting

What? It Glows? This is a-rare fine. This ring from around the 1930's features a Lab Grown Spinel measuring 24.97 x 18.06 x 10.24mm oval Lab Grown Spinel. When put under a Fluorescence light it glows a strong green. This was purchased from an Antique Dealer. Set in a handmade yellow gold setting, this would be a prize to own for sure!
