Here is a genuine druzy geode and black onyx pin made by an artist. The druzy is set on the sterling base with stylized prongs and is open at the back. The bottom part is not attached to the base and is able to be moved up and down slightly. In the lower right hand corner is a round black onyx stone. The greenish tints on the sterling part are not verdigris but part of the design of the pin. It measures 2" X 1 3/4". Excellent condition.
