Lab Grown Diamond Engagement Rings

Find your engagement ring style

Solitaire rings keep the focus on a center diamond. Halo rings frame it with smaller stones, while a hidden halo adds detail beneath the center. Three-stone rings pair a center with two side stones. Explore vintage-inspired designs, pavé shoulders, botanical leaves and tulip baskets for a more detailed look. Vintage-inspired describes the design, not an antique age.

Compare diamond shape, size and budget

Available designs include round, oval, marquise, pear, emerald-cut, radiant and hexagon lab-grown diamonds. Compare millimeter dimensions, on-hand photographs and setting proportions alongside carat weight. A longer outline can look different from a rounder diamond of similar weight. Choose a budget, then compare the complete ring in your preferred metal.

Center-stone weight is different from total carat weight (TCW or TW), which includes the other diamonds. For example, the round-and-pear trilogy lists a 1.00 CT center plus 0.34 CT combined pear side stones. The oval hidden-halo pavé design lists a 1.50 CT center plus 0.77 CT combined accents. Confirm the selected stones and final measurements before production.

Choose the metal, setting and fit

Selected listings offer 10K, 14K and 18K gold in yellow, white or rose, plus 925 silver; availability varies by ring. Prongs show more of the diamond’s outline, while bezels surround its edge with metal. Check band width, thickness and setting height, especially if you want a matching band to sit flush. Available sizes commonly span US 3–13, with fractional sizes shown on each product. Use our US and Canadian ring-size guide and ask about resizing suitability and charges for your chosen design.

Lab-grown diamonds and certification

Lab-grown diamonds have the same essential chemical, physical and optical properties as mined diamonds, with a laboratory origin. Moissanite is a different gemstone. Read our diamond and moissanite comparison. IGI certification is included on specified listings, including the round-and-pear trilogy; other listings offer it as a paid service. Confirm the report, stones covered and any fee for your selection.

Custom orders, shipping and aftercare

Request a custom engagement ring to discuss diamond size, metal, engraving or design changes. Applicable listings describe CAD approval, diamond images and final photos or video before dispatch.

Shipping to the United States and Canada is available. Making time and delivery estimates vary by design. Review the product estimate and confirm production, shipping, duties and taxes for your destination before ordering. For a proposal deadline, ask about the complete timeline rather than treating the ship date as an arrival date. Confirm the selected ring’s warranty terms and aftercare coverage.

Read the return and exchange policy before ordering: eligible unused, unworn items require a return request within 30 days of delivery, with original packaging and applicable certificates. Custom-made, modified and personalized items are excluded from refunds; engraved items are excluded from returns or exchanges. Contact us before returning an item; customers prepay return shipping.
