How much bigger a 3 carat looks

Measurements below come from IGI-graded lab-grown stones in our supplier feed, October 2026.

Center	Face-up size
2ct oval	about 9.9–10.6 mm long, 7.0–7.2 mm wide
2ct round	about 8.0–8.2 mm across
3ct oval	about 11.4–12.1 mm long, 8.0–8.2 mm wide
3ct round	about 9.2–9.4 mm across

A 3 carat oval is about 1.5 mm longer and 1 mm wider than a 2 carat. We confirm the exact millimeters on the stone you choose, and you see the size on the finger in your 3D render before production.

Buying tips

• Compare the same specs: keep color, clarity, shape and metal the same when you compare 2 and 3 carat prices, or the gap is not a fair one.
• Look at 2.5 carats: a 2.5 carat sits between the two and is quoted on your specs. See 2 carat oval prices and 3 carat oval prices.
• Stay in 14K gold: 18K gold and platinum cost more. See 14K vs 18K vs platinum.
• Plan ahead: standard delivery is 4–5 weeks after 3D approval and payment. A rush is $250 for 2–3 weeks.
