Radiant Cut Natural Diamond Engagement Rings

Radiant Natural Diamond Engagement Rings, Priced from the Center Stone Up

Every one of the 500 or more radiant natural diamond engagement ring designs in the grid above takes its center from the 12,178 natural radiant diamonds we hold today. Of those stones, 10,173 can be viewed in 360 HD video before you decide. The stone accounts for most of what you pay. After the current savings the cheapest natural radiant is $200, and in the 0.90 to 1.10 carat band, the size the designs are pictured with, the floor is $685 and the median is $2,398. With a 1.02 carat natural radiant in place, three of the radiant engagement ring designs on this page price out at $3,755 for the Linda comfort fit solitaire, $4,085 for the Vivian solitaire and $4,540 for the Bellora hidden halo. All three are in 14K white gold, and all three prices include the stone. Stock figures were pulled on October 17, 2026 and are refreshed regularly.

A radiant cut engagement ring carries a rectangular outline with the sparkle pattern of a round brilliant. The cut also hides inclusions better than any other shape, so more of the budget can go to size instead of clarity. Natural radiants are a small market, so the stock figures in the table below matter as much as the prices.

Natural Radiant Stones Sorted by Carat Band

All 12,178 natural radiants in our inventory appear in the table, sorted into carat bands, so the stock column adds up to that figure. The 0.50 to 0.89 ct band holds the most stones at 4,063. Median prices read $2,398 for 0.90 to 1.10 carats, $12,448 for 1.90 to 2.10 and $32,298 for 2.90 to 3.10. A finished radiant engagement ring costs the center stone plus the design. Put a different stone in the same design and the price moves with that stone. Where a ring page exists for a band in the same origin, the band links to it.

Choosing Color and Clarity in a Natural Radiant

Hold clarity at VS2 among natural radiants of 0.90 to 1.10 carats and the lowest prices run $1,285 for D, $1,360 for G, $930 for H and $1,065 for I. With color held at G to H instead, VS1 begins at $1,160, VS2 at $930 and SI1 at $1,055. Those grade steps are where the budget for a natural radiant is decided. G to H color and VS2 to SI1 clarity is what most buyers settle on, after checking the video so that no dark inclusion lands in an exposed part of the stone. Metal belongs in that decision too, because yellow and rose gold warm the stone's color.

Lowest price per grade among natural radiants of 0.90 to 1.10 ct: the color column holds VS2 clarity (567 stones), the clarity column holds G to H color (926 stones)

Same Ring, Lab Grown Radiant Center

Put a lab grown radiant in the same design and the numbers change. A one carat G color VS1 radiant opens at $405 lab grown against $1,505 natural, and the one carat band medians come to $597 and $2,398. A lab stone brings a larger size and a higher grade at a given price, while the natural stone is priced for its scarcity; 11,879 of the 12,178 radiants here come with GIA reports. The radiant lab grown diamond engagement rings page shows these same designs with lab centers, and the radiant diamonds grid carries both origins.

Setting Styles for a Radiant Cut

Four corner prongs or a bezel hold a natural radiant and leave the cut to carry the look. The crushed ice sparkle shows most on a plain band or beside simple pavé. A radiant cut engagement ring with a halo makes a one carat stone look a good deal larger, and because the corners are cropped there is no need for V prongs.

At one carat a natural radiant measures roughly 6.5 by 5 mm, which is about the size pictured in the radiant cut engagement ring designs on this page. Each is shown in 14K white gold and also made in yellow gold, rose gold and platinum, with your chosen stone shown in the mounting. Every stone in the list carries two scores: the AI price score, which measures it against similar natural radiants on the list and marks one that costs more than its peers, and the quality score, out of 18, which combines cut, color and clarity in a single figure. None of our gemologists earn a commission, and you can reach them by chat or phone to go through two or three radiant finalists together on video.

Today's Price of a Radiant Natural Diamond Engagement Ring

The grid prices every design as a complete ring, built around a default center that today is a 1.02 carat natural radiant in 14K white gold. The amounts in the table are therefore ring prices for that stone and not prices for the mounting alone. Of the first designs shown, the Linda comfort fit solitaire at $3,755 is the lowest and the Bellora hidden halo at $4,540 the highest. The difference between those two is entirely the setting; a plain comfort fit solitaire sits at the bottom of the range and pavé or hidden halo designs at the top. Pick any other natural radiant out of the 12,178 on hand and the radiant natural diamond engagement ring you are looking at reprices around that stone.
