0.75 Carat Lab Grown Diamond Engagement Rings

0.75 Carat Lab Grown Diamond Engagement Rings: How the Stones Split by Shape and Grade

Every 0.75 carat lab grown diamond engagement ring design on this page, and there are 680 or more of them, is built around a lab stone you pick yourself. The pool is the 26,134 in stock between 0.70 and 0.80 carats, 15,257 of which have 360 HD video. Once the current savings are in, that band bottoms out at $135, with $245 as its median. Most of the designs are shown with a round, and a 0.75 carat lab round begins at $150 with a median of $261. When the page displays the designs with a 1 carat lab round, as it does today, the Linda comfort fit solitaire comes to $915, the Vivian solitaire to $1,245 and the Bellora hidden halo to $1,695. Each is a design from this 0.75 carat lab diamond engagement ring page, shown in 14K white gold with the stone included in the price. The stock figures date from October 19, 2026 and are refreshed regularly.

Three quarters of a carat gets left out of most price guides even though it is the weight on most hands. A 0.75 carat round measures about 5.8 mm across, only 0.7 mm less than a full carat. In lab grown the entire band costs less than a plain setting does. The designs on this page are the ones the site shows at one carat, with a lighter stone in the head and a lower price on the ring.

Lab Grown Center Stones in the Band, Shape by Shape

Rounds account for 9,899 of the 26,134 stones in the table below and have a median of $261, and ovals, at 6,002, are the second largest group. The rows together make up the headline figure, since every stone in the band belongs to one shape. Among the medians, the oval is the least expensive shape at this weight at $239 and the princess the most expensive at $278. An oval, pear or marquise of this size faces up larger than a round does, so it covers more of the finger for less money. The shape names link to their own lab ring pages, where the designs reappear with a center of that shape at this weight.

Below and Above the 0.75 Carat Mark

Of the stones in the band, 17,767 weigh between 0.70 and 0.74 carats and have a median of $251. The 8,367 that weigh 0.75 to 0.80 carats have a median of $248. On rounds with the grade held at D to F and VS2 or better, the median is $262 below the mark and $265 above it. Crossing it therefore costs $3 for a change in diameter nobody can see, and that gap is small enough in lab grown that most buyers take the round number.

What Color and Clarity Cost in a Lab Grown Round of This Weight

Hold clarity at VS2 or better and 99 percent of the 0.75 carat lab rounds on the color ladder fall in D to F. On that ladder D opens at $160 and G at $165. Hold color at D to F instead and VS1 opens at $150, VVS2 at $170. A natural buyer agonizes over those steps, but in lab grown at this weight they cost almost nothing extra. The sensible lab ring at this size is therefore D to F color, VS1 or better and an Excellent cut, with whatever remains spent on the setting and on weight.

Two ladders for 0.75 ct lab rounds, 0.70 to 0.80 ct: lowest price per color grade when clarity is VS2 or better (9,485 stones), then lowest price per clarity grade at D to F color (9,770 stones)

Price of the Same Ring with a Natural Center Stone

A G color VS1 round at this weight opens at $210 lab grown and at $840 natural, and the band medians across every shape sit at $245 and $1,125. There are 68,116 natural stones in the band against 26,134 lab grown. Natural is the scarcer of the two origins, and 63,263 of those 68,116 natural stones carry GIA reports. The lab stone matches the natural one in size and in sparkle at a fraction of the price. For these designs priced the other way around, see the 0.75 carat natural diamond engagement rings page.

Which Settings Suit a Stone This Size

A band of 1.5 to 1.8 mm and a low four prong head suit a lab stone of this size and keep it from looking lost. A thin halo is the usual way to give a 0.75 carat lab diamond engagement ring the presence of a carat and a half. Lab pricing also leaves money over for a heavier band and more metal if that is the preference. A bezel is worth considering at this size for anyone who wants a lab ring that catches on nothing.

Face up, a round at this weight spans roughly 5.8 mm, while a cushion spans 5.3 mm, an emerald cut 6 x 4 mm and an oval 7 x 5 mm. That is why the longer shapes look bigger at equal weight. Put an oval or a pear on a slim band and the result is the biggest looking 0.75 carat lab grown engagement ring at this price. Every design on the page can be set with a 0.75 ct lab round, and the images show it in 14K white gold. Each one can also be ordered in yellow gold, rose gold or platinum, with whichever stone you select in the head.
