These spiky little cones are commonly found on the shores of Hawaii; you have probably stepped on them if you have ever visited the islands! Through the tumbling and polishing process these cones are no longer spiky in feel, and will not feel sharp against your skin. I just love the texture to these cones, and the depth of the detail is just stunning! They are a smaller cone; around 2.5 cms long by 1.75 cms wide. They are sold on 18″ a sterling silver chain.
