This is such a creative design by DeLizza and Elster! It looks like a huge geode just as it comes from the mine. The stone is highly textured and has great dimension. You can wear it as a pin or a pendant. The "geode" is glass similar to a rhinestone. It is surrounded by aurora borealis rhinestone chatons. This is a sparkling jewel. If you see any dark spots on the stones it is a reflection from the camera. They are in excellent condition. Pin comes with a 24" goldtone chain. The pendant is 2" x 1 1/2". There is minor wear to the coating on the underside of the geode but it doesn't impact the beauty and sparkle of the stone.
