Loose IGI-Certified Lab-Grown Diamonds
By Lavora Diamonds, Provo, Utah. Updated October 2026.
Can I buy a loose IGI-certified lab-grown diamond?
Short answer: yes. Lavora Diamonds sources loose lab-grown diamonds with an IGI report on every stone, quoted on your exact shape, carat, color and clarity, and ships them free and fully insured anywhere in the US. Our published stone-only record is a 3.52ct cushion modified brilliant, E/VVS2, at $2,649 for the stone alone. Natural diamonds over 1ct are available too.
How much is a loose 3 carat lab-grown diamond?
The 3.52ct E/VVS2 cushion above is our published reference. Price moves with cut, color, clarity and measurements, so every loose stone is quoted on your grades. For comparison, a completed 3.50ct oval ring with a hidden halo in 14K yellow gold came to $2,799 complete.
| Record | Price | Source |
|---|---|---|
| 3.52ct cushion modified brilliant · E / VVS2 · IGI | $2,649 stone only | Real ring prices (stone-only record) |
| 3.50ct oval · 14K yellow · hidden halo (complete ring) | $2,799 complete | Completed build |
| 1ct · 14K · solitaire (complete ring) | $2,000 complete-ring minimum | Design desk / minimum |
Completed prices are past Lavora builds (completed ring prices · price per carat index); design-desk estimates are ranges, not fixed prices. Your exact price comes with your 3D model.
How much is a 1 carat or 5 carat loose lab-grown diamond?
We quote loose 1ct and 5ct stones on your grades from current IGI-certified stone lists rather than publishing a list price. If you plan to set it, a complete 1ct 14K solitaire comes in at the $2,000 complete-ring minimum.
How to check a loose lab-grown diamond before you buy
- Get the IGI report number and verify it at igi.org.
- Match the report to the stone: shape, carat, color, clarity and millimeter measurements.
- Ask for a video of the actual stone, not a stock image.
- Our standard is VS1 clarity or better; D–F color and VVS are available.
Can you set a loose diamond later?
Yes. We can design a custom setting around your stone, shown as a 3D render first, often within 24–48 hours, for a $50 design fee that is fully refundable and credited to your ring. Delivery takes 4–5 weeks after 3D approval and payment, and a $250 rush (14–21 days) is available.
