Cheapest way to get a 3 carat lab-grown engagement ring

What is the cheapest way to get a 3 carat lab-grown engagement ring?

Short answer: at Lavora Diamonds, the lowest-cost way to a 3 carat ring is a lab-grown center in a simple 14K gold solitaire. A 3 carat oval or round solitaire (D–E color, VS1+ clarity) in 14K yellow gold is estimated at $2,625–$2,925 complete on our ring price estimator, including the IGI-certified center, the setting and your custom 3D render.

By Lavora Diamonds, Provo, Utah. Updated October 2026.

Three choices keep a 3 carat price down: a lab-grown center, a solitaire instead of a pavé band, and 14K gold instead of 18K gold or platinum. Spending on grades you cannot see adds cost without adding size. Our default center is D–E color with VS1+ clarity, quoted on the exact stone you choose. Complete engagement rings have a $2,000 minimum.

How big is a 3 carat diamond?

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

Center	Face-up size
3ct oval	about 11.4–12.1 mm long, 8.0–8.2 mm wide
3ct round	about 9.2–9.4 mm across
3.5ct oval	about 11.8–13.1 mm long, 8.1–8.6 mm wide

An oval faces up longer than a round of the same weight. We confirm the exact millimeters on the stone you choose before production.

Buying tips

• Pick a solitaire: on our estimator a 3ct oval solitaire is $2,625–$2,925, while a 3ct oval with a pavé band in 14K white gold is $3,500–$3,875.
• Stay in 14K gold: 18K gold and platinum cost more. See 14K vs 18K vs platinum.
• Skip invisible grades: a completed 3.16ct D/IF oval came to $3,249, and a completed 4.02ct E/VS1+ oval came to $3,349. Nearly a full carat more cost only a little more, because the grades were lower.
• Plan ahead: standard production is 4–5 weeks after 3D approval and payment. A rush is $250, so ordering early avoids that fee. See rush cost and timeline.
