Lab-Grown Diamond Knife Edge Wedding Bands, grown in light.
A ridge down the middle, light on each side. Knife edge wedding bands climb to a slim peak along the crown, and these line rows of round lab-grown diamonds against that crest. Some carry a double row of pavé split by the ridge; one adds milgrain for a vintage finish. Metal, karat and carat weight are set on the product page.
The peaked profile
Seen end-on, a knife edge band looks like a shallow roof: two faces rising to a narrow apex. From above, the ring therefore reads narrower than it measures, and it throws a bright line of reflection along the top. Stones set on the angled faces tilt outward and pick up side light.
Double row or half eternity
- Double row pavé: two tracks of stones meeting at a raised divider.
- Half eternity: stones only across the upper half, plain metal underneath.
- Milgrain sides: beaded borders that soften the sharp geometry.
Most offer 0.25 to 0.5 ct total weight.
Matching a knife edge engagement ring
Paired with a knife edge band engagement ring, a knife edge wedding band with lab-grown diamonds follows the same roofline, so the pair lies flush on the finger. Metals are white, yellow or rose gold in 10K, 14K or 18K, platinum, or Silvadium, Novara's tarnish-resistant sterling silver.
Wear on the apex
The crest meets every countertop first and shows wear before the rest. Platinum and 14K or 18K gold keep that line sharp longest; silver rounds off sooner. Rinse the pavé in mild suds now and then, and book a yearly prong check with your jeweler.
Ring questions, answered.
How do I choose an engagement ring?
Start with the shape she loves, then the setting style. Our gemologists can help you balance carat, cut and budget on a free video call.
Can I build my own engagement ring?
Yes — pick a setting, then a diamond, and review the finished ring before it goes to the bench.
Does the diamond price include the setting?
Diamond and setting are priced separately in the ring builder, and the total is shown before you add the ring to your bag.
How do I find my ring size?
Use our ring size guide, or order a free ring sizer — it arrives in 2–3 days.
Can I return or resize my ring?
You can return it within 30 days (a 10% restocking fee applies to resized or engraved pieces), and your first resize within 60 days of delivery is free.
Should I insure my engagement ring?
We recommend it. Every ring ships fully insured; once it is yours, a separate jewelry insurance policy covers loss, theft and accidental damage.
