Elegant  Ring Sterling Silver 925 with Raw Druzy Rainbow Carborundum, Armenian Handmade Jewelry, Gift for Her

Silver ring with black carborundum, on the surface of which there is an iridescent effect – colored overflows. Carborundum is an amazing “cosmic” stone that shimmers with all the colors of the rainbow and beckons with a brilliant shine. Strictly speaking, it is not even a mineral, but an alloy of silica and carbon; it practically does not occur on Earth, and most of the specimens were obtained in laboratory conditions. A small amount of carborundum was found in meteorite debris, and this material is quite common in space. Natural carborundum is born outside the solar system, near carbon-rich stellar giants, and is unlikely to ever become available to us.
