A beautiful vintage Edwardian - Art Deco two-tone 14K gold marquise shaped camphor glass (rock crystal) stick pin, set with a genuine diamond. Not marked but acid tested. The diamond & camphor were tested with a Presidium gem tester. The stick pin measures 2.5" long and weighs 1.8 grams. I estimate the diamond to be .20 - .25 ctw. The marquise setting is ornately etched along the sides. Excellent vintage condition, with no issues noted. **The box pictured is a photo prop and is not included**
