Baseline Pricingīased on what is available in our inventory, the vast majority of rubies that weigh around 1 carat are at least $1,000 per carat. However, the exact colors that barely qualify as pink or red in corundum is an ongoing debate. Despite being the same material, there is a significant price difference between corundum labelled as “pink sapphire” versus “ruby” with ruby material commanding higher prices. There is no such thing as a light ruby, only pink sapphires.

In rubies this is a little limited since the only color they can be is primarily red, with a medium to dark tone, though colors modifying the red are permissible. This single factor is the main drive to an entire industry. Despite all the considerations though, the one factor that is prized above all else is the color. What dictates the price is the quality of the gem and its color, clarity, cut, and carat weight, though other factors can further determine ruby pricing like treatments, international customs, and overall rarity of desirable features. One of the most expensive rubies ever sold is the Sunrise Ruby, selling for over a million dollars a carat at 25 carats. Rubies can run as little as $1 a carat to $100,000+ a carat, depending on the 4Cs. Note that carat weight is the unit of measurement that most gemstones are weighted by (1 carat = 0.2 grams).

Like any other gemstone, the cost of a ruby can vary depending on the quality and carat weight.
