By Lavora Diamonds, Provo, Utah. Updated October 2026.
Three choices put the money into size: a lab-grown center, an oval shape, and a solitaire in 14K gold. Grades above D–E color and VS1+ clarity cost more without looking bigger. 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.

Why an oval looks bigger
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 |
| 2ct oval | about 9.9–10.6 mm long, 7.0–7.2 mm wide |
| 2ct round | about 8.0–8.2 mm across |
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
- Spend on carat, not 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.
- Pick a solitaire: a simple solitaire keeps the money in the center stone. See pavé band prices for the difference.
- 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, so ordering early avoids that fee.

Ring budget questions
What engagement ring gives the most diamond for the money?
At Lavora Diamonds, the most diamond for the money is a lab-grown oval center in a simple 14K gold solitaire. A 3 carat oval solitaire (D–E color, VS1+ clarity) in 14K yellow gold is estimated at $2,625–$2,925 complete, and a 4 carat is $3,150–$3,500, on our ring price estimator, including the IGI-certified center, setting and your custom 3D render.
Do higher clarity grades make a ring look bigger?
No. A completed 3.16ct D/IF oval came to $3,249, and a completed 4.02ct E/VS1+ oval came to $3,349, so lower grades bought nearly a full carat more for only a little more. Our default is D–E color with VS1+ clarity.
Does an oval look bigger than a round?
Yes. In IGI-graded lab-grown stones from our supplier feed, a 3ct oval is about 11.4–12.1 mm long, while a 3ct round is about 9.2–9.4 mm across.
How big a lab-grown diamond can I get around $3,000?
On our ring price estimator, a 3.5ct D–E/VS1+ oval solitaire in 14K yellow gold is $2,575–$3,025 complete, and a 3ct is $2,625–$2,925.
Is platinum worth it for the most diamond per dollar?
Yes. Platinum and 18K gold are offered and are quoted on your specs; both cost more than the 14K gold in our estimates. We show the metal in your 3D render before production.
How do I pay for a custom ring?
Production begins after 3D approval and payment. Klarna and Affirm financing are available on your invoice. Complete engagement rings have a $2,000 minimum.
