Turquoise Cabochons |
|||
|
Turquoise has been used in jewelry since the time of the pharaohs in ancient Egypt. Turquoise is most often shaped into a cabochon for use in jewelry. It is an opaque stone often with a bright robin’s egg blue color that indicates the presence of copper. North American specimens often contain inclusions from oxides that form during their creation. This matrix can include sandstone, limonite, malachite, chrysocolla, jasper or psilomelane. The veins in some stones interlock in patterns to form "spider-web" turquoise. Click on image for details |
