1.5 Carat Lab Grown Diamond Engagement Rings

A 1.5 carat centre stone sits in the gap most buyers arrive at after seeing 1 carat in person and wanting slightly more. It reads noticeably larger on the hand without moving into statement territory or statement pricing. Every stone here is a real CVD lab grown diamond, VVS clarity, D-E-F colorless, IGI certified.

Is 1.5 carats visibly bigger than 1 carat?

Yes, but modestly. A 1.5 carat round measures about 7.4mm against 6.5mm for a 1 carat, so roughly 14 percent wider. The difference is clear side by side and subtle in isolation, which is why elongated shapes are popular at this weight.

Which shapes make the most of 1.5 carats?

Oval, marquise and pear, because they spread weight across the surface. A 1.5 carat oval covers noticeably more finger than a 1.5 carat round and is often mistaken for a 2 carat stone.
