Popularly known as Dragon’s Eye, Red Tiger Eye jewelry received its name because of its luminescent stripes resembling the tiger’s stripes. Although it’s not rare, it is believed to be a newly discovered gem. The red tiger eye forms when the quartz stone is replaced by crocidolite (which is a blue form of asbestos). As this process happens, iron is oxidized, transforming into limonite. We can say that the red tiger eye is nothing but limonite ingrained inside a clear quartz.Red Tiger Eye is associated with the tectosilicate mineral family, which is a semi-precious type of quartz having vertical luminescent bands.
