Brazilian Medusa Quartz (Paraiba Quartz) 0.400ct Loose
Medusa quartz contains inclusions of the mineral giralite inside the crystal. It is sometimes called giralite in quartz, but the GIA has named it "Medusa quartz" because the inclusions resemble a jellyfish called "Medusa Jellyfish." It also has several nicknames, such as "Paraiba quartz" because its beautiful blue color is reminiscent of Paraiba tourmaline and because it was mined in Paraiba, Brazil, where Paraiba tourmaline is produced. Enjoy the mysterious and beautiful world that unfolds inside the stone.
