Mid century 10K white gold cultured pearl and spinel ring. This wonderful ring reminds me of a ballerina's tutu. The top of the ring is an undulating ribbon of textured white gold. In the center, sits a cultured pearl, surrounded by six small prong set white spinel stones. The inside of the band is market 10K GTR, with GTR being the maker's mark. The ring is 18mm in diameter, and the cultured pearl is 8mm. The ring is in great condition, showing light wear to the band. It s a size 6, and dates to the Mad Men era of the 1950's - 1960's.
