3 carat engagement rings are unmistakable luxury — a round 3ct stone measures about 9.3mm and commands attention from across the room. Custom-made in every cut and metal, natural or lab-created.
3 carat buying guide & FAQ
How big is a 3 carat ring? About 9.3mm for a round stone; an elongated oval or emerald cut of 3ct looks even larger face-up.
Is a 3 carat moissanite worth it? Yes for size-first buyers — it delivers the full 3ct look with more fire than diamond at a far lower price.
