my parents just moved and I found this ring and wanted to know if any one knew anything about it.View attachment 849179View attachment 849180View attachment 849181
i don't think synthetic opals were around in the 1930's....
There were an abundance of early attempts to imitate opals. We've got dozens of deco era pieces in stock with faux opals. Usually glass impregnated with foils. It would be somewhat unusual to encounter an opal that size in anything but solid precious metal.
