Marquise Cut Natural Diamond Engagement Rings

Marquise Natural Diamond Engagement Rings: Where the Price Comes From

The cheapest natural marquise in our inventory is $150 after today's savings, and the median for a stone in the 0.90 to 1.10 carat band is $2,746. That gap is worth knowing before you look at designs, since the center stone makes up the larger share of the ring price and the mounting the smaller. The band itself, which is the size the designs are shown with, opens at $770. Rare Carat offers 590 or more marquise natural diamond engagement ring designs here. Each one is built around a center you pick yourself from the 36,522 natural marquise diamonds available today, 23,829 of them with 360 HD video. With a 1.01 carat natural marquise in 14K white gold, the Bellora hidden halo comes to $4,805, the Vivian solitaire to $4,355 and the Hayden curved vine to $4,495, stone included in each figure. Inventory counts and prices were taken on October 17, 2026 and are refreshed regularly.

Carat for carat, a natural marquise covers more of the finger than any other shape, and at one carat it costs less than a round. That explains why the cut is coming back at a time when buyers want size. Its two points are where color shows first and where a chip is most likely, so a marquise engagement ring is built around guarding them.

What Each Carat Band of Natural Marquise Costs

Weight alone separates the rows in this table. The median climbs from $2,746 at 0.90 to 1.10 carats to $15,839 at 1.90 to 2.10 and on to $37,565 at 2.90 to 3.10. Every natural marquise on the diamond grid falls into one of these bands, so the stock column adds back up to the 36,522 stones quoted above. The fullest row is the one under 0.50 ct, which holds 22,499 of them. To get the finished ring price you add the setting you choose to the stone price, and a different stone in that design moves the total with it. Where a carat band has a ring page of its own, the row links across so you can look at the designs at that weight.

Picking Color and Clarity in a Natural Marquise

Holding natural marquises at 0.90 to 1.10 carats and VS2 clarity, the cheapest I color is $1,395 and the cheapest D is $2,715, so color on its own can nearly double the entry price. H opens at $1,995 and G at $2,905. Run the matching ladder on clarity with color pinned at G to H and SI1 opens at $1,570, then VS2 at $1,995, then VS1 at $2,145. These two ladders are where the budget for a natural marquise ring is decided. Most buyers settle on G to H color with VS2 to SI1 clarity, picked on the video so that no dark inclusion sits where the prongs cannot cover it. They weigh the metal as well, because yellow and rose gold warm the stone.

The Same Ring with a Lab Grown Marquise

Put a lab grown marquise in the same mounting and the numbers move to a different range. A one carat G color VS1 opens at $440 lab grown against $2,145 natural, and across that whole band the medians are $674 and $2,746. The first pair is matched on grade and weight, so origin alone explains that difference. Going lab grown gets you more size and higher grades for an equal outlay, while going natural means paying for scarcity. Of the 36,522 natural marquises here, 30,946 come with GIA reports. The marquise lab grown diamond engagement rings page runs the same designs with lab stones, and the marquise diamonds grid lists both origins together.

How a Marquise Should Be Set

V shaped prongs cap both points of a natural marquise, with two or four more prongs along the sides, or else the whole stone sits inside a bezel. If the bare outline of a marquise engagement ring looks too thin, a halo fills it out. A plain solitaire lets the full length of the stone show. Metal plays a part too, because an H or I natural marquise looks whiter at the tips in yellow gold than the same stone does in platinum.

At one carat a natural marquise runs close to 10 by 5 mm, which is roughly the size of the stone each marquise diamond ring on this page is shown with, in 14K white gold. Every design comes in yellow gold, rose gold and platinum as well, and the picture updates to show the exact stone you pick in the metal you pick. Two scores appear next to every diamond on the grid. The AI price score measures the stone against similar natural marquises available right now and flags one that is priced above its peers. The quality score, which runs out of 18, folds cut, color and clarity into a single number. Our gemologists are paid no commission, and when you reach them by chat or phone they will put two or three marquise finalists on video and compare them with you.

Today's Prices for a Marquise Natural Diamond Engagement Ring

Among the first designs on the grid the cheapest complete ring is the Marigold six prong tulip at $4,110 and the most expensive is the Bellora hidden halo at $4,805. Every one of them is priced with one default center, a 1.01 carat natural marquise in 14K white gold, so the whole of that gap is the mounting. A comfort fit solitaire with nothing added costs the least, and a pavé band or a hidden halo costs the most. What the table shows are finished ring prices for that stone, not bare setting prices. Pick a different natural marquise from the 36,522 available and each marquise natural diamond engagement ring is repriced around the stone you chose.
