      About One Carat Diamond Rings

      The price of a one-carat diamond ring will depend on the cut, color, and clarity of the stone. An internally flawless stone will cost more than one that is eye clean, and a naturally colored diamond will generally cost more than a colorless one of the same quality, depending on the color. The most important factor, though, is what you find the most beautiful and meaningful.

      One Carat Diamond Ring Designs

      A one-carat diamond ring is usually the ideal size for stacking with other rings, since it will stand out but not overwhelm or be overwhelmed by other rings.

      • Beautiful Cut - Depending on the cut, a one-carat diamond will measure approximately 6-7 millimeters in a round cut or old European cut.
      • Timeless Settings - If you want to add more visual heft to a one-carat ring, you can pick a halo or cluster setting that surrounds the diamond with other stones of the same color.
      • Diamond Size - Typically, when somebody refers to a one-carat diamond ring, they mean a ring with a one-carat stone, but sometimes it refers to the total weight of all the stones, so be sure to specify what you are looking for.
