Ouro Verde Meaning “green gold” in Portuguese, ouro verde is a type of quartz found in Brazil. Its name comes from its color, which is a vivid chartreuse hue with yellow highlights. Most ouro verde today is produced by heat-treating (irradiating) amethyst or yellow quartz, which gives the transparent stone its pale, golden-green color. Also known as "green gold", the name of this gem can also be spelled “oro verde.” It ranks a 7.0 on the Mohs Scale and is spectacular for jewelry.
