How much does a lab grown engagement ring cost by carat
A lab grown diamond engagement ring is the finished piece, center stone and setting together, not a loose stone. In 2026 that finished ring runs about $1,028 to $2,800 at Draco depending on carat. The table below uses real catalog rings, each IGI certified, each linked to its page. Prices are base 10K gold; the same design in silver runs about 30 percent less. For loose stone pricing per carat, see the companion guide on how much you should pay per carat.
| Carat | Representative ring | From (CAD) |
|---|---|---|
| 0.30 ct | 0.30ct trinity engagement ring | $1,028 |
| 1 ct | 1ct crescent contour solitaire | $1,311 |
| 1.5 ct | 1.5ct heart ring | $1,955 |
| 2 ct | 2ct pear halo ring | $1,801 |
| 2.5 ct | 2.5ct elongated radiant ring | $2,481 |
| 3 ct | 3ct marquise ring set | $2,885 |
A second 1 carat solitaire, the open French pavé band, sits at $1,410, which is why the practical 1 carat figure most buyers quote is around $1,300. At 2 carats the range runs from $1,801 for the pear halo up to $2,571 for a three stone pear, depending on setting.
"With a natural diamond, the price per carat climbs as the stone grows. With lab grown it falls. The bigger ring is the better value per carat, not the worse one."
Garrett McMartin, Founder, Draco Diamond
Why a bigger lab ring costs less per carat
Run the math on the prices above and the pattern is clear. The 0.30 carat ring works out to about $3,427 per center carat. The 1 carat solitaire is about $1,311 per carat. The 2 carat pear halo is about $901 per carat. The 3 carat set is about $826 per carat. Per-carat cost roughly quarters from the smallest ring to the largest. Natural diamonds do the reverse, where a 2 carat can cost four times a 1 carat of the same quality, because large rough is genuinely scarce. Lab production scales, so size is no longer the rarity tax it once was.
What actually sets the price
A finished ring price is the center stone plus the setting. The center stone is the larger lever, driven by carat first, then cut, color, and clarity. Every Draco stone holds E to F color and VS2 clarity or better, so the variable buyers control is carat and shape. The setting is the second lever. Metal sets the floor: silver runs about 30 percent below the 10K gold base, while 14K, 18K, and platinum step up from there. Design adds the rest, since a halo or pavé band carries more small stones and more labour than a plain solitaire. Shape matters too, as an elongated cut such as oval, pear, or marquise reads larger per carat, so it buys visual size without buying more weight.

Are lab rings cheaper than natural
Yes, and the gap widens with size. A 1 carat lab grown engagement ring at around $1,300 sits well below a comparable natural ring, where the loose stone alone often costs several times that before the setting is added. At 2 carats the gap is larger still, because the natural per-carat premium compounds while the lab per-carat cost falls. The optical result is identical: a lab grown diamond is chemically and physically the same as a mined diamond, certified by IGI to the same scale. The difference the eye cannot see is the price. For the full side by side, see the lab grown versus natural price comparison.
How to budget for the ring
Set the budget first, then let the lab inversion work for you. Decide a number, then pick the carat that fits inside it rather than stretching for the next size. Choose the metal, since moving from 10K gold to silver drops the finished price about 30 percent, and moving up to 18K or platinum raises it. Protect cut at every size, because a well cut 1.5 carat outshines a dull 2 carat. Confirm the certificate, since every Draco order includes the IGI report, available on request. The certificate documents the same E to F color and VS2 clarity or better across the catalog.
