Glowing Onyx Lamp 5x5x8″
Onyx is a type of chalcedony, which is itself a form of microcrystalline quartz. Onyxes have straight, nearly parallel bands or layers of color, which allow skilled gem carvers to cut away material to create cameos and intaglios with extraordinary depth and contrast.
The gemstone has a white base and white upper layer but may have bands of multiple other colours between those layers. Onyx can also be of a single colour, and in the case of Sard Onyx, the layers are of brown colour. You may also come across some entirely black coloured Onyx stone.
Onyx gemstone is carved into alluring cameos due to its bands of colours and doing this maximizes the banding. The beautiful gemstone is also cut in glossy cabochons and can also be used to make beads or pendants.
