Vintage Cameo Incolay Cufflinks Featuring Artemis or Diana Greek Mythology

Set of vintage cufflinks. Artemis or Dianna who were both goddesses of the hunt and Moon, in what appears to be Incolay stone. These are unmarked. I learned this from another seller on E-tsy. “Incolay is a brand name for a type of man-made stone that "is a complex combination of various colored natural minerals and coupling agents." The white decoration on the top of the stone is hand applied and fuses to the stone underneath creating a unique product that is made to closely resemble the finest museum cameos. Because the stones are handmade, no two are alike.” These are a little more than 1” square. In the original box. Please look closely at the pictures as are an important part of the description.
