How expensive is garnet?
The prices of garnets vary greatly. Red garnet or pyrope garnet is more plentiful than other garnet species, so it is quite cheap. Retail prices can range from $3 to $50 per carat. Mandarin garnet and travorite garnet are extremely rare garnet varieties, especially in large size. Retail prices of top-grade stones can be as high as $1500 to $3000 per carat.
