MINERAL GEM WORLD  

PARABIA QUARTZ

 

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.

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.

 Quartz is a macrocrystalline variety of the mineral Quartz (SiO2). Quartz is the most abundant single mineral on earth. It makes up about 12% of the earth's crust, occurring in a wide variety of igneous, metamorphic and sedimentary rocks.

Quartz varieties are commonly separated into two groups based on the size of the individual grains or crystals; macrocrystalline quartz in which individual crystals are distinguishable with the naked eye, and cryptocrystalline quartz in which the individual crystals are too small to be easily distinguishable under the light microscope.
