The setting on this piece is just as beautiful as the unique cameo. Made of solid 10 karat yellow gold the flanks of the ring branch out to 14 Millimeters wide. The cameo is in the solid bezel setting with a closed back. On the one side near his back shoulder there is an indentation in the gold from when it was made. There are no markings but the gold was tested by our jeweler. The cameo features a gentleman and a collared shirt with wavy, receding hairline and full beard. I wish I knew who he was! The cameo measures 19 by 15 Millimeters and we believe that it is plastic, not stone. When you shake the piece the cameo does not move, but you can hear something is trapped between the cameo and gold. Don't you wonder what it is?!? The ring is a size 6.25 and weighs 8.5 grams.
