How Much Does a 2.5 Carat Lab-Grown Ring Cost? (2026)

By Lavora Diamonds, Provo, Utah. Updated October 19, 2026.

How much does a 2.5 carat lab-grown diamond engagement ring cost in 2026?

Short answer: at Lavora Diamonds, a complete 2.5 carat E–F/VVS2 lab-grown solitaire in solid 14K gold is estimated at $2,400–$2,650, and $2,700–$3,000 with a hidden halo. That includes the IGI-certified center, the custom setting, your 3D render and production. A completed 2.50ct E VS1 oval in 14K gold came to $2,243 complete. Complete engagement rings have a $2,000 minimum, so every 2.5ct design sits above it.

2.5ct pear · E–F/VVS2 · 14K rose · solitaire	$2,400–$2,650	Desk estimate

E–F/VVS2 rows are design-desk estimates: (setting + IGI-certified diamond + insured shipping) × 3.15, shown as a ±5% range. F/VS1 rows come from our ring price estimator (VS1 stones price below VVS2). 18K gold and platinum are quoted on your specs.

2 carat vs 2.5 carat vs 3 carat

Center	Complete ring, 14K solitaire (E–F/VVS2)	Source
2ct	$2,175–$2,425	Design-desk preset
2.5ct	$2,400–$2,650	Desk estimate
3ct	$2,625–$2,925 (about $2,775)	Design-desk preset

Moving from 2ct to 2.5ct raises the estimate by about $225, and moving on to 3ct adds another $225–$275. Elongated shapes such as oval, pear and marquise look larger face-up per carat than a round, so a 2.5ct oval can read close to a 3ct round on the hand. Your 3D render shows the face-up size before anything is made. More detail: 2 carat ring price · 3 carat ring cost.
