Carat Cut Color Clarity The Carat Weight The word carat derives from the word carob, a Mediterranean seed, which has an extremely consistent weight for measuring. The greater the carat weight, the rarer, and more valuable the diamond becomes. Five metric carats weighs exactly 1 gram. Some people want the largest diamond possible. If size is a priority, we at Diamonds Direct can help you classify the proper cut, color and clarity to fit your budget economically, and fit your jewelry beautifully. Many of our engagement rings can fit diamonds up to 5.00 carats, but each ring has different size constraints based on its size and the type of setting. Prong settings can be manipulated to fit virtually any size diamond, but tension-set diamonds and bezel set diamonds have more limitations on size. .25 CT (4.1 MM) .5 CT (5.1 MM) .75 CT (5.8 MM) 1 CT (6.4 MM) 1.25 CT (6.9 MM) 1.5 CT (7.4 MM) 1.75 CT (7.8 MM) 2 CT + (8.1 MM) 17.9 MM Shop Loose Diamonds About Our Jewelry BROWSE ENGAGEMENT RINGS BROWSE WEDDING BANDS CUSTOM JEWELRY DESIGN DESIGN YOUR RING ONLINE Our Collections DIAMONDS DIRECT BRIDAL GARY & DAVID WEDDING BAND COLLECTION LULINI COLLECTION THE SUNBRIGHT COLLECTION Our Store OUR HISTORY OUR SERVICES PRIVACY POLICY PRODUCT CARE FOR JEWELRY PURCHASE POLICIES & GUARANTEES Join Our Newsletter Sign up for special offers and discounts Enter your email address Follow Us © 2021 Diamonds Direct.
