How much is a 3 carat lab-grown round brilliant?
A 3ct 14K round solitaire is estimated at about $2,775 ($2,625–$2,925) on our design desk, with VS1+ clarity. Rounds show the most sparkle per carat; ovals, radiants and elongated cushions spread wider on the finger at the same weight.
Can a 3 carat ring fit under $5,000?
Yes. Every completed 3ct-class Lavora build on this page landed under $3,600, so a $5,000 budget leaves room for a hidden halo, a pavé band, 18K gold or a matching band. For what $5,000 buys at 4ct and up, see engagement rings under $5,000.
3 carat price by shape
Each shape has its own page with its 14K estimate, completed builds where we have them, and FAQs. Our default center is D–E color with VS1+ clarity on every shape.

What moves the price at 3 carats?
| Factor | What it does |
|---|---|
| Shape | Ovals, radiants and cushions price differently per carat than rounds and can look larger on the hand. |
| Color | Our default center is D–E color, which reads icy white in white or yellow gold. |
| Clarity | Our standard is VS1+, which is typically eye-clean. VVS is available as an upgrade. |
| Setting | On our 3ct design-desk estimates, a hidden halo adds about $175 over a solitaire. Pavé, 18K and platinum are quoted on your specs. |
Where 3 carat budgets get wasted
Our completed 4.02ct oval in E/VS1+ cost $100 more than our 3.16ct in D/Internally Flawless ($3,349 vs $3,249). The grades that dropped are not visible without magnification, so at 3 carats the money is usually better spent on cut, shape and setting than on the last rungs of the certificate.
Every lab-grown center is IGI-certified, and our default is D–E color with VS1+ clarity (VVS clarity is available as an upgrade). You see a 3D render first, often within 24–48 hours, for a $50 design fee that is fully refundable and credited to your ring, with unlimited revisions. Delivery takes 4–5 weeks after 3D approval and payment, and a $250 rush takes 2–3 weeks (14–21 days). Engraving is complimentary, US shipping is free and fully insured, and every ring comes with a Lifetime craftsmanship warranty, plus free resizing within the first 60 days.
