How Much Does a 1.5 Carat Lab-Grown Ring Cost? (2026)

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

How much does a 1.5 carat lab-grown diamond ring cost?

Short answer: at Lavora Diamonds, a complete 1.5 carat IGI-certified lab-grown solitaire in solid 14K gold lands between the $2,000 complete-ring minimum and about $2,300, our 2ct oval solitaire design-desk preset. That includes the custom 3D render, setting and production. A completed 2.00ct marquise bezel solitaire came to $2,149.

Build	Price	Source
1ct · 14K · solitaire	$2,000 (complete-ring minimum)	Design desk / minimum
1.5ct · 14K · solitaire	between $2,000 and about $2,300	Bracketed by the minimum and the 2ct preset
2ct oval · 14K · solitaire	about $2,300 ($2,175–$2,425)	Design-desk preset
2.00ct marquise · 14K yellow · bezel solitaire	$2,149 complete	Completed build

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.

Is 1.5 carats the smart size to buy?

It is a middle ground: noticeably bigger on the hand than 1ct. At Lavora the jump to 2ct is small because complete rings start at the $2,000 minimum, so it is worth pricing both sizes on the same shape and grades before you decide.

Demand concentrates at round numbers, so a 1.40ct with the same grades can cost less than a 1.50ct with no visible difference on the hand. Elongated shapes like oval and pear look bigger at the same weight.

How do you avoid overpaying for a 1.5 carat ring?

1. Ask for an itemized quote: stone and setting as separate lines.
2. Get the IGI or GIA report number and verify it at igi.org or gia.edu.
3. Confirm the setting is solid 14K or 18K gold, not plated.
4. Compare written quotes on the same certified specs.

Every lab-grown center is IGI-certified, and our standard is VS1+ clarity in D–E color (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 a free resize within 60 days.
