The price range for 1-carat diamonds is between $3,080 and $26,950 per carat. The price of a 1-carat diamond depends on many factors and can therefore vary greatly.
The price of a diamond depends not just on its size but also on its quality, color, certification and, in some instances, its cut. Diamond experts use a very complicated process to ascertain a diamond's quality and price it accordingly. Remember that size does not necessarily matter when it comes to the price of diamonds.
The 1-carat diamond has become a standard size for engagement rings around the world, reports Washington Diamond.
