Converting Half Moon Cut Diamonds from Millimeters to Carat Weight

Half Moon Loose Diamond Side Stones

Half Moon Diamond Side Stones

Half moon diamonds were created specifically to use as side stones. They give a round center stone in a diamond engagement ring a larger look and will highlight the brilliance of a round or oval center stone in a diamond pendant necklace. You can also be creative and use half-moons as side stones for an item of jewelry containing a heart shaped center stone.

Half-moon diamonds are also a great choice as side stones for a marquise shaped diamond center stone and customers usually choose half-moon pairs equaling less than 1 carat in order to accentuate the size of the center stone. CaratsDirect2U has white half-moon diamond pairs available in a variety of color and clarity grades. If you already have a center stone and are looking to match them to side stones, we can find the right half-moon diamond pair for you.
