Ruby

Ruby is one of the most popular jewelry stones. Fine-quality rubies are some of the most expensive gemstones. However, rubies are also subjected to more treatments than almost any other gem. For this reason, ruby prices can range from a few hundred dollars a carat to thousands of dollars per carat.
