FAQs About 1 Carat Diamonds
The size of a 1 carat diamond varies based on the diamond shape selected. Our diamond size chart breaks down the differences in the shapes.
When you want the look of a 1 carat diamond without a hefty price tag, consider "buying shy." This means purchasing a diamond with a carat size of .90 to .99 instead of a full carat. The difference won't be very discernible to the eye, but it will lower the price.
