Garnet (Pyrope)

Precious Gemstone

What is Garnet (Pyrope)?

Pyrope is a member of the garnet group of minerals. It is prized for its deep red color, often described as resembling the color of pomegranate seeds, hence the name 'pyrope' which comes from the Greek word 'pyrōpos' meaning 'fire-eyed'. Pyrope is a magnesium aluminum silicate, and its rich color is often due to the presence of iron and chromium. It is a popular gemstone used in jewelry due to its beauty, durability, and relatively high refractive index, which gives it a brilliant luster.
