What a beautiful and unusual piece this one is! I have never seen agate before with so much pink! It was very difficult to photograph, because the light would catch it and make glare. I finally got a decent one inside with flash with my new camera. I think this is about 1820. Amazingly the pearls are stitched in, which is a sign of quite early work. The heart measures 1 inch and 1/4 North to South, and 1 inch East to West. The heart is surrounded with beautiful natural pearls and gold beads and the piece is unmarked but tested 18 ct. The forces of nature really went all out when they formed this lovely piece of art!
