Brilliant beauty that sets
your diamond ring apart

A 3 carat diamond is an excellent choice for a ring

If you want a diamond ring more special than what most people have, a 3 carat diamond is an excellent choice.

Carat is one of the 4Cs that affects the price of a diamond. Many people think carat is a unit of size, but it is in fact a unit of weight. The word carat comes from the Carob seed, which was used centuries ago to determine the weight of precious stones as the seeds have a uniform weight. When diamonds are weighed, they are given a carat weight commonly rounded off to the second decimal place. One full carat weighs 200 milligrams, or 0.007 ounces.

Another diamond size? 1 carat diamond, 2 carat diamond, 4 carat diamond, 5 carat diamond, 6 carat diamond, 7 carat diamond, 8 carat diamond, 9 carat diamond, 10 carat diamond or go to the Diamond Wholesale Prices

How much does it cost?

That is why just one 3 carat diamond will be worth much more than three 1 carat diamonds. In fact, carat weight does not affect value or size proportionately. A 1 carat Round Brilliant Cut has a diameter of 6.5mm, whereas a 3 carat Round Brilliant Cut is 9.3mm. As for the price per carat, a 3 carat diamond weighing 600 milligrams ranges between $6,050 and $ 84,810 per carat.
