POLISHED PURPLE (MORADO) OPAL

Morado opal, also known as purple opal or opal royale, is a variety of common opal found in central Mexico. Morado means "purple" in Spanish, hence the name. Unlike precious opals, it does not exhibit color play (opalescence). The purple coloration is due to tiny fluorite inclusions within the silica, which can sometimes cause morado opal to exhibit a blue to violet fluorescence under a shortwave UV light.
