Herkimer Diamond Natural Crystals Undrilled

We hunted high and low to find these as we love them so much and we are sure you will do too! These gorgeous, double-terminated quartz crystals come from the Herkimer region in the US and although they are not actually real diamonds when you see how they twinkle with mirror-like shine and rainbow sparkles it is obvious why they got their name. These are a lovely natural alternative to cut faceted beads and will look stunning included in your designs.
