4 Carat Lab Grown Diamond Engagement Rings

Four carats is a size mined diamonds put out of reach for almost every buyer. Grown in a laboratory the same stone becomes attainable without dropping clarity or colour to afford it. Every stone here is a real lab grown diamond, VVS-VS clarity, D-E-F colorless, with an IGI report for every lab grown diamond of 1 carat or more.

What changes at 4 carats?

Practicality becomes the main consideration rather than price. A 4 carat round is around 10.2mm wide, which sits across most of the finger. Profile height matters more than anything: a low setting wears comfortably, a high one catches constantly.

Which shape works best at this size?

Elongated cuts, for a different reason than at smaller weights. A 4 carat round can look almost spherical on a slim finger, while a radiant, oval or emerald at the same weight distributes the mass along the finger and reads more elegant than sheer. See these shapes and more in our lab grown diamond engagement rings.

Frequently asked questions

Which metal should the shank be? Platinum or 18K gold, both for strength and because the metal needs to look substantial enough to carry the stone.

Is it certified? Yes, IGI, with full documentation and a laser-inscribed report number.
