Medusa Quartz is also known as and sometimes sold as Paraiba quartz because the small deposit was found in the Paraiba state of Brazil.

This new type of included quartz gemstone was discovered in August 2004 in Brazil.It is very rare and in very limited supply.

Contains rare copper mineral Gilalite (Cu5Si6O17·7H2O) Called Bolinhas (small balls) or Medusa Quartz (Jellyfish) that shows small globular aggregates of fibrous crystals. The name is due to the shape of the aggregates remembreing Jellyfish.

GIA has an article in Gems & Gemology, called “Medusa Quartz” with gilalite inclusions in the Fall 2005, Volume 41, issue 3.

Under magnification, some resemble the shape of a floating jellyfish named medusas rondeau. Thus the name Medusa quartz. This is 100% natural from the earth and indentification of the inclusions were performed by the National Museum of Natural History in Paris.
