Sponge Coral Pendant
Eye-catching sponge coral pendant boasting rich orange colour and exceptionally subtle markings. Crafted by hand in a fine sterling silver setting, this light weight ladies pendant is one of only a very small number of sponge coral pendants that we currently have available.
Correctly known as melithaea ochracea, sponge coral is correctly classified as a coral not a sponge but may be freely traded because it's not considered to be endangered. It comes primarily from the South China Sea and is porous and very soft grading just 3½ to 4 on Mohs scale of mineral hardness so it must be treated with care.
Most of the sponge coral which is transformed into gemstones has been stabilized because its natural tree-like structure is full of tiny holes which have been created by polyps. The holes give it an appearance similar to that of a sponge hence some say it's the reason for the name "sponge" coral. When rocks and minerals are stabilized they're filled with a resin or other material/s to stop them from eroding or crumbling but can also be a way of strengthening or repairing the object so that it may then be used for another purpose such as a gemstone.
This highly polished sponge coral pendant has been crafted by hand exclusively for Stone Mania by one of a small team of talented artisans with whom we have been working for almost twenty years. Although most likely to be an impromptu purchase, we're confident that you'll love having it as part of your collection of gemstone jewellery.
