How many carats is a 7mm Sapphire?

1 Answer
How many carats is a 7mm Sapphire?
A standard size of a round sapphire is 6mm which is approximately one carat, making 7mm sapphires just slightly larger than a carat. Because sapphires are heavier than diamonds, a one carat sapphire is slightly smaller than a one carat diamond.
