Q. Is garnet an expensive stone?

Answer

Prices vary widely, from around $500 for a carat that has some imperfections to over $7,000 for a carat that is flawless and huge. As the most expensive kind of garnet, Demantoid commands the highest prices. Each carat of diamond costs $15,000. Cost: $10,000 per carat for Alexanderite. Each carat of red beryl costs $10,000. Garnets of the Demantoid kind cost $10,000 per carat. Smaller, less flawless stones with good color can be purchased for as little as $500 a carat, while bigger, more flawless stones of top color can cost as much as $2,000 to $7,000. In addition to being one of the rarest colored gemstones, demantoid garnet also happens to be the rarest kind of garnet.
