How Much Does a 4 Carat Lab-Grown Diamond Ring Cost? (Real 2026 Receipts)
Real Pricing · Updated July 2026
How much does a 4-carat lab-grown ring actually cost?
Four carats is where retail markup does its most damage — because the bigger the stone, the bigger the percentage on top of it. It's also where comparing quotes saves the most money in actual dollars. These are real Lavora client receipts, next to the written quotes those couples brought in.

At 4 carats, the details matter more.
| Factor | Why it matters at this size |
|---|---|
| Cut quality | At 4ct, a poorly cut stone looks glassy and dark. Excellent cut is non-negotiable — it's what makes the size read brilliant instead of big |
| Elongated shapes | Ovals and radiants spread wider per carat — a 4ct elongated stone can face up like a 4.5ct round |
| Color in yellow gold | G–H color disappears against 14k yellow — the most requested combination in our archive |
| The certificate | At this spend, never buy uncertified. Every Lavora stone carries an IGI report you can verify at igi.org |
The $4,000 question.
One client was quoted $8,512 for a 4.00ct H VS2 oval. We built the identical certified specs for $4,020. Same stone grade, same solid gold, custom setting — $4,492 stayed in their pocket. That's not a discount. That's what the ring costs without a showroom attached to it.
4-carat questions.
Is a 4-carat lab-grown diamond worth it?
If she loves the look, this is the size range where lab-grown is at its most compelling — a 4ct mined stone runs well into five figures, while the identical-looking lab-grown stone is thousands, not tens of thousands.
What budget do I need for 4 carats?
Most complete 4ct custom builds at Lavora land between $4,000 and $5,500, depending on shape, color, clarity, and setting. Text your specs for an exact number.
Will people know it's lab-grown?
No — not visually, not with a loupe. Only a lab with specialized equipment can tell, and the IGI report discloses it honestly. Same crystal, different birthplace.
How fast can I get it?
Pricing in 12 hours, CAD in 24–48 hours, finished ring in about three weeks — insured, IGI certificate in the box. Proposal date? We plan around it.
