Pear & Radiant Cut Lab-Grown Diamond Prices (2026)
Last updated July 2026
Pear and radiant cuts sit in an interesting corner of the 2026 market: both are brilliant-faceted — full sparkle, not the quiet flash of a step cut — and both are elongated shapes that read larger than their carat weight. Here is what IGI-certified lab-grown pear and radiant cut diamonds actually cost at 2026 market prices, how they compare to rounds, and what a complete custom ring runs at each size.
How much do pear and radiant cut lab-grown diamonds cost in 2026?
Prices below are for IGI-certified lab-grown stones in the most-purchased spec range — F–G color, VS clarity, excellent cut. Fancy shapes like pear and radiant typically price a few percent under an equivalent round, because round rough carries the highest demand. "Direct" is the loose-stone price at custom studios and online-direct vendors; "typical retail" is what a comparable certified stone commonly runs inside a traditional store's finished-ring pricing.
| CARAT SIZE | PEAR (DIRECT) | RADIANT (DIRECT) | TYPICAL RETAIL EQUIVALENT |
|---|---|---|---|
| 1.00ct | $430–$710 | $420–$700 | $1,100–$1,900 |
| 1.50ct | $660–$1,060 | $650–$1,050 | $1,700–$2,700 |
| 2.00ct | $1,100–$1,800 | $1,100–$1,750 | $3,300–$4,800 |
| 2.50ct | $1,400–$2,300 | $1,400–$2,250 | $4,300–$6,200 |
| 3.00ct | $2,250–$3,800 | $2,200–$3,700 | $7,500–$11,500 |
The pattern matches the wider lab-grown market: price per carat steps up at each milestone weight, and the retail gap widens with size — roughly 2–2.5x direct pricing at 1ct, and 3x or more by 3ct. The round-shape baseline is in our 1ct–3ct lab-grown price chart, and the other two elongated shapes are covered in our marquise and emerald cut price guide.
Why does a pear look bigger than its carat weight?
The pear's teardrop outline spreads weight into one of the largest face-up areas per carat of any shape — a 1.5ct pear can read close to a 2ct round from conversation distance. Two things to check before buying: the length-to-width ratio (most buyers land between 1.45 and 1.75 — shorter reads stubby, longer reads narrow) and the bow-tie, the darker band that crosses the center of every elongated brilliant. A faint bow-tie is normal; a black stripe is a cut problem. Ask for a video of the exact stone, not a stock render. In the setting, the point is the vulnerable spot — it should sit under a V-prong.
What should you check on a radiant cut before buying?
The radiant is the workhorse of the elongated shapes: brilliant faceting inside an emerald-cut outline, with trimmed corners that make it the most durable rectangular choice for daily wear — no exposed points at all. Its dense facet pattern is also the most forgiving of inclusions of any shape here, which means clarity budget goes further: a VS2, and often an eye-clean SI1, looks identical to the eye in a radiant while costing meaningfully less. Length-to-width is preference — near-square (1.05–1.2) reads modern, elongated (1.3–1.5) reads closer to an emerald cut with sparkle.
What does a complete custom ring cost in these shapes?
Add a solid 14k gold setting — roughly $900–$1,200 for a solitaire, up to about $2,000 for a hidden halo with pavé — plus design and production labor. In practice a complete custom 1–1.5ct pear or radiant ring starts around $2,000, a 2ct build typically lands in the $3,000–$4,500 range, and a 3ct build in the $4,500–$7,000 range at direct pricing. Both shapes suit the east-west and bezel settings trending in 2026, and neither trend adds cost at a custom studio.
How do you check that a pear or radiant quote is fair?
Three checks, in order: get the quote itemized — stone, setting, and labor as separate lines; look up the IGI or GIA certificate number on the lab's own database and confirm carat, color, clarity, and dimensions match what you were sold; then price the identical certificate at two other vendors. Fancy shapes are where quiet markup hides most often, because fewer buyers know the comparison numbers above.

FAQ
Q: Are pear and radiant cuts less expensive than round?
A: At the same certified grades, yes — typically a few percent under an equivalent round, because round rough carries the highest demand.
Q: How much is a 2 carat pear cut lab-grown diamond in 2026?
A: Roughly $1,100–$1,800 direct in the F–G / VS range; comparable certified stones commonly run $3,300–$4,800 at traditional retail.
Q: Which looks bigger, a pear or a radiant?
A: Pear — its teardrop outline has among the largest face-up areas per carat of any shape. An elongated radiant reads larger than a near-square one at the same weight.
Q: Can I drop clarity on a radiant cut?
A: It is the best shape to do it in — the dense brilliant faceting masks inclusions, so an eye-clean VS2 or SI1 usually looks identical to a VS1 on the hand.
Q: Can I get a pear or radiant ring for under $4,000?
A: Comfortably — a 1.5–2ct certified center in a solid 14k custom setting fits inside $4,000 at 2026 direct prices.
