How much is a 2 carat lab-grown cushion cut diamond?

A 2 carat lab-grown cushion cut diamond costs about $2,310 to $4,210 as a loose stone in Australia, with a median of $2,616. That is the middle 80% of the 51 cushion cuts between 2.00 and 2.09 carats on our live feed on 17 September 2026. Every stone is D to F colour, VS1 clarity or better, and IGI certified.

Set in a finished engagement ring, a 2 carat cushion costs $4,350 to $5,350 in 18k gold, or $4,400 to $5,500 in platinum. Those are the fixed prices of our five complete 2 carat cushion rings, each made with a 2.00 to 2.09ct, E to F colour, VVS1 clarity centre stone.

What a 2 carat cushion cut costs by carat weight

2.30 to 2.49ct19$2,364 to $6,654$4,6359.0 x 6.9mm

12 stones listed at more than twice the median for their group are left out of the price ranges, because they are priced far above stones of the same weight and grade.

Cushions break the usual pattern. The stones just under 2 carats were more expensive, with a median of $2,774 against $2,616 at 2 carats, and price per carat was lowest in the 2.00 to 2.09ct group at $1,275. Above 2.20 carats, medians jumped past $4,000. For a cushion, an exact 2 carat stone is the sweet spot rather than something to avoid.

Square or elongated: how the outline changes the price

Cushion cuts come in two outlines, and the feed was split almost evenly between them. The typical size in the table above averages both, so here they are separately at 2.00 to 2.09ct:

OutlineStonesMedian priceTypical size
Square cushion, ratio under 1.1023$2,7097.8 x 7.5mm
Elongated cushion, ratio 1.15 or more26$2,6148.6 x 6.7mm

An elongated cushion costs slightly less at the median and looks longer on the finger. A square cushion looks softer and more traditional. Within the elongated group, stones around a ratio of 1.25 had the lowest median at $2,381, while the squarest stones at 1.00 were among the highest at $3,306.

How clarity and colour change a cushion's price

Clarity at 2.00 to 2.09ctStonesPrice rangeMedian price
VS119$2,308 to $4,209$2,570
VVS217$2,215 to $3,363$2,605
VVS115$2,287 to $5,266$2,799

3 stones listed at more than twice the median for their group are left out of the price ranges, because they are priced far above stones of the same weight and grade.

The three clarity grades sat within about $230 of each other at the median. A cushion's larger facets show inclusions a little more than a round, so VVS2 is a comfortable middle choice. Colour was unusual: D colour had the lowest median at $2,570, against $2,610 for F and $2,799 for E, so there is no reason to settle below D on a cushion if you want the whitest stone.

Does going under 2 carats save money on a cushion?

Carat weightVS1 medianVVS2 medianVVS1 median
1.90 to 1.99ct$2,734 (6 stones)$2,482 (6 stones)$4,075 (5 stones)
2.00 to 2.09ct$2,570 (19 stones)$2,605 (17 stones)$2,799 (15 stones)

2.30 to 2.49ct$4,027 (9 stones)$4,778 (6 stones)$6,100 (4 stones)

No. At VS1 and VVS1 the stones just under 2 carats cost more than the 2 carat stones, and only at VVS2 were they about $120 cheaper. The under 2 carat rows hold only five or six stones each, so read single figures with care, but the direction is consistent.

How much is a complete 2 carat cushion cut engagement ring?

Every ring below comes with a 2.00 to 2.09ct, E to F colour, VVS1 clarity, IGI certified cushion, set on a 2mm band in solid 18k gold or platinum. The price includes the diamond and the setting:

RingStyle18k goldPlatinum
MaraSolitaire$4,350$4,400

SamaraHalo$4,800$4,950
RiverThree stone with pear side stones$5,150$5,300
CamilaHalo with a 3/4 pavé band$5,350$5,500

At that stone grade, a loose 2 carat cushion runs $2,287 to $5,266 on its own, with a median of $2,799. The solitaire starts at $4,350, a hidden halo or halo adds $300 to $450, and the three-stone and halo with pavé band designs run to $5,350.
