Round Solitaire Engagement Rings
A round solitaire pairs the most brilliant diamond cut with the simplest setting, and that's exactly why it's the most enduring engagement ring there is: a single round brilliant on a plain band, nothing to distract from the stone's fire. This collection holds 198 round solitaire lab-grown diamond engagement rings, from $863, each IGI-certified and made to order in solid 10K, 14K or 18K gold.
Why the round brilliant solitaire endures
The round brilliant is cut with 57 to 58 facets engineered to return the maximum amount of light, making it the most sparkling of all diamond shapes. A solitaire setting puts that sparkle centre stage with no side stones or halo competing for attention. It's the ring that never dates and pairs cleanly with any wedding band — the default for a reason.
Styles in this collection
The collection spans classic four and six-prong round solitaires, low-profile and cathedral settings, knife-edge and tapered bands, and hidden-detail settings with pavé or a surprise stone under the head. Centre sizes run from around one carat to three carats and above.
Lab-grown, IGI-certified
Every diamond is lab-grown and IGI-certified — identical in carbon, hardness and fire to a mined diamond, at a fraction of the cost. That saving is what lets you choose a larger, cleaner centre stone within the same budget.
Shop with confidence
Each ring is made to order in about two weeks, ships free by express courier in 5–7 days, and is covered by a 30-day return policy, with the IGI certificate included.

How to choose a round solitaire engagement ring
With nothing beside the stone, a round brilliant solitaire lives or dies on cut grade — it is the single line on the certificate that most changes what your eye receives, so hold out for Excellent or Ideal. Aim for a table of 54–60% and depth of 59–62.5%; outside that window brightness drops. For reference, a well-cut 1-carat faces up about 6.4mm, a 1.5-carat about 7.4mm, a 2-carat about 8.1mm — useful when you picture a 2 carat round diamond solitaire engagement ring on the hand.
Choose the prong count for lifestyle: a four-prong crown shows more diamond, a six-prong holds more securely and reads slightly rounder. Because a solitaire pairs cleanly with any band, you can keep the engagement ring simple and add sparkle later with a pavé band or a round solitaire ring enhancer that frames the stone. If a stone is priced surprisingly low for its weight, check the depth percentage first — that is usually where the discount is hiding.
Round solitaire engagement ring FAQs
What is a round brilliant solitaire?
A round brilliant solitaire engagement ring sets a single round brilliant-cut diamond — the 57 to 58 facet cut engineered for maximum sparkle — on a plain band, with no side stones or halo. It's the most classic engagement ring style.
What is a round solitaire ring enhancer?
A round solitaire ring enhancer is a separate band, often with pavé or a curved shape, that wraps around an existing solitaire to add sparkle or frame the centre stone — a way to change the look without replacing the ring.
What carat size works for a round solitaire?
Round solitaires are popular from 1 to 3 carats. A 2 carat round diamond solitaire engagement ring is a substantial classic choice, while a 3ct round solitaire diamond ring reads as a clear statement. Because it's a solitaire, the full carat weight is on display.
What wedding band goes with a round solitaire?
Almost any. A round solitaire's clean profile lets a plain, pavé, or eternity band sit flush against it — one of the reasons the round cut solitaire engagement rings style stays so versatile.
Are round solitaire lab grown diamonds real?
Yes. A round brilliant diamond solitaire ring made with a lab-grown stone is chemically and optically identical to a mined diamond, IGI-certified to the same standards and classified by the FTC as a real diamond.
Why are round diamonds priced higher per carat?
Cutting a round brilliant wastes more of the rough crystal than any other shape, which raises the price per carat. Lab-grown pricing softens that premium considerably, making a larger round solitaire more attainable.
