1 Carat Diamonds

A 1 carat diamond weighs 0.20 grams and is the most-requested size for engagement rings. Vaalberg offers certified 1 carat loose diamonds in every shape, both lab-grown and natural, each GIA or IGI graded with free EU shipping. Actual face-up size varies by shape — elongated cuts like oval and marquise look larger than a round of the same weight.
