The word Pyrope (Garnet) comes from the Greek ‘pyropos,’ meaning fiery. Its blood red color is due to iron and chromium content. The composition is magnesium aluminum silicate with a MOH’s hardness of 7 1/4. Pyrope is found in volcanic rock and alluvial deposits in Arizona-USA, South Africa, Argentina, Australia, Brazil, Myanmar, Scotland, Switzerland, and Tanzania. It has been used in jewelry for over 500 years.
