4 Carat Lab-Grown Diamonds
4 carat lab-grown diamonds across every cut
A 4 carat lab-grown diamond is a substantial, confident size. Carat measures weight, not diameter, and face-up size varies by cut - elongated shapes like oval and marquise read larger than their carat suggests. Prices step up at round carat numbers, so a stone just under 4 carats can offer better value for a near-identical look.
