2 Carat Lab-Grown Diamonds
The popular sweet spot — about 8mm across in a round, substantial presence that's still easy to wear daily.
How big is a 2 carat lab grown diamond?
A 2 carat round measures roughly 8mm across — noticeably bigger than a 1 carat and a real statement on the hand, yet still comfortable for everyday wear. It's become the popular "sweet spot" size, and lab grown is the reason it's now within reach for so many shoppers.
How much does a 2 carat lab grown diamond cost?
Diamond prices rise steeply with size, so a mined 2 carat costs far more than two 1-carats. A lab grown 2 carat changes that math entirely — you get the same look for a fraction of the price. The exact figure depends on the 4Cs, so filter the live collection above to see real prices in your budget.
Getting the most from 2 carats
- Cut first — at this size, cut quality is what makes it come alive.
- Shape — elongated cuts look even larger than a round at 2 carats.
- Colour & clarity — G–H and VS–SI stay eye-clean and white at this size for strong value.
