This exceptional vintage Gem-Craft circle brooch is 10K gold plated with sparkly pave rhinestones and black lucite faceted stones. It is clean and in very good condition. The design has a very attractive modern 70's look, and it is also very beautiful. The cut-out raised circles in between the rhinestones and faceted square lucite stones protrude out over 1/16th of an inch. This gives it a three dimensional design that is very cool. All the stones are set with an open back. It measures 2 5/16 inches in total diameter, edge to edge. The inside open area diameter measures 1 7/8 inches. It is signed Craft, which is one of the marks used by Gem-Craft jewelry company which started business in 1945 until present. I believe it is circa 70's. This particular mark was used in 1979, but may have been used in other years as well.
