1 Carat Lab Grown Diamond Engagement Rings

1 Carat Lab Grown Diamond Engagement Rings: Choosing the Stone First

Settings and stones are priced separately here, so the cost of a complete ring is easy to work out. The six settings we priced below run from $605 for the Linda comfort fit solitaire to $1,385 for the Bellora hidden halo in 14K white gold, and most 1 carat lab grown stones cost $405 to $925 (median $555). Put together, that is about $1,010 to $2,310 for most rings, against $1,850 to $6,000 with a natural center. If none of these designs suits, the full catalog of 691 settings runs from $480 to $5,195.

The first decision is the center stone, since each of the 670 or more 1 carat lab grown diamond engagement ring designs here is built around one you pick yourself. Rare Carat has 246,616 lab grown diamonds in the 0.90 to 1.10 carat range in stock today, and 204,467 of them have been filmed in 360 HD video. After the current savings the cheapest of those is $320 and the median is $556. Most designs are shown with a round, and a 1 carat lab round begins at $330 with a median of $464. With that round in place, the 1 ct designs include the Linda comfort fit solitaire ($915), the Vivian solitaire ($1,245) and the Bellora hidden halo ($1,695), all in 14K white gold and all priced with the stone included. These figures were pulled from inventory on October 16, 2026 and get refreshed as stock moves, which keeps the price beside each 1 carat lab grown engagement ring here current.

This is the benchmark size, about 6.5 mm across in a round, and in lab grown it has turned into a routine purchase because the diamond now costs less than most of the settings it goes into. A 1 carat lab grown engagement ring is therefore priced mainly by its design. That is also how the designs here are shown, each with a one carat lab round in place.

How the Shapes Compare at This Weight, Lab Grown

Once the size is settled, shape comes next, and the table below divides all 246,616 stones in the band so the rows add back up to the headline count. Rounds account for 116,459 of them with a median of $464. No other shape has a median under $464, which makes the round the cheapest shape at this weight, while the marquise at a $674 median is the most expensive. Ovals are the second deepest shape, with 24,248 stones. An oval, pear or marquise spreads its weight across a longer outline, so a 1 carat stone in one of those shapes covers more of the finger than a round does, although the round stays the cheapest shape here by median.

Either Side of the 1 Carat Mark

Some buyers plan to shop a little below the mark to save, so the band is split here on each side of it. There are 24,423 stones between 0.90 and 0.99 carats at a median of $493, against 222,193 between 1.00 and 1.10 carats at a median of $562. With the grade pinned to D to F and VS2 or better on rounds, the median of the lighter group is $478 and that of the heavier group $464. Buying shy of the mark therefore saves nothing in a one carat lab stone, and the round number is the one to take.

Color and Clarity Choices on a Lab Grown Round

Grade is the next decision after shape, and in lab grown at this weight it barely moves the price. Hold clarity at VS2 or better and 97 percent of the 1 carat lab rounds on the color ladder fall in D to F, with D opening at $370 and G also at $370. Hold color at D to F instead and VS1 opens at $370, with VVS2 at $380. The grades that natural buyers agonize over cost next to nothing here, so a one carat lab ring is normally best ordered in D to F, VS1 or better, with an Excellent cut, and the money saved on grade put toward the setting or a little more weight.

Opening prices for 1 ct lab rounds (0.90 to 1.10 ct): each color at VS2 or better (114,691 stones), then each clarity at D to F (113,059 stones)

If You Would Rather Have the Natural Stone

Before settling on lab grown, look at the natural price for the same stone. A 1 carat G color VS1 round opens at $370 in lab grown and $1,475 in natural, and across every shape the medians for the band are $556 and $2,390. Natural stock is far thinner, 77,788 stones against 246,616 lab, though 68,226 of those 77,788 carry GIA reports. A lab stone of the same grade matches it for size and sparkle at a fraction of the price, and what the natural premium buys is scarcity. The same designs priced with natural centers are on the 1 carat natural diamond engagement rings page.

Choosing the Setting Once the Stone Is Picked

With the stone chosen, the setting is the next decision, and a 1 carat lab diamond engagement ring can take any of the classic ones. The reference point is a four prong solitaire on a band of 1.8 to 2 mm. Six prongs read a touch more traditional, a hidden halo adds sparkle underneath without changing the view from above, and a full halo makes the center look a size bigger. Because the lab stone costs so little, there is also money left for a heavier band and extra metal. If the design has pavé, keep those accent stones small, since larger ones compete with a center of this size.

Across the top, a 1 carat round comes in at roughly 6.4 to 6.5 mm, an oval at 7.5 x 5.5 mm, an emerald cut at 6.5 x 4.5 mm and a cushion at 5.5 to 6 mm. The elongated shapes therefore look bigger at the same weight, and a lab grown oval or pear of one carat on a slim band gives the largest look for the money. Every 1 carat lab grown diamond engagement ring here is pictured in 14K white gold with a lab round, and the same design can be ordered in yellow gold, rose gold or platinum with whichever stone you picked. Our gemologists are paid no commission, they are reachable by chat or by phone, and they will put your finalists for a 1 carat lab diamond engagement ring side by side on video with you.

Today's Price of a 1 Carat Lab Grown Diamond Engagement Ring

Each design in the grid is priced as a finished ring, and the default center today is a 1 carat lab round set in 14K white gold, so the prices in the table below already include the stone. Among the first designs shown, the Linda comfort fit solitaire is the low end at $915 and the Bellora hidden halo the high end at $1,695. The gap between those two is entirely the setting, since both carry the same default stone, and the gap between this page and the natural page comes from the stone alone. Choose a different stone from the 246,616 lab grown diamonds in this weight range and the 1 carat lab grown diamond engagement ring is repriced around your choice before checkout.

Stone counts and stone prices in this section describe every lab grown diamond from 0.90 to 1.10 carats in Rare Carat's inventory as of October 16, 2026 under the filters the diamond grids themselves use: a Good cut or better, a GIA, IGI or GCAL report, with or without video, any color from D to K and any clarity from FL to SI2. That comes to 246,616 lab grown stones, 204,467 of them with 360 HD video, plus 77,788 natural stones used for the comparison. Prices are what you would pay today after the current savings; the regular price appears struck through beside each stone. A starting price in any row means the least expensive stone in that row, whatever its grade or weight happens to be. The ring prices are those displayed on this page on October 17, 2026 for finished rings in 14K white gold and with the center stone named in the row, and the design count is read off the page. The color and clarity ladders and the matched grade table use rounds in the band only, because on rounds grade rather than shape drives the price.
