Lab-Grown Diamond Curved Bar Necklaces
An arc of stones along the collarbone. These curved lab-grown diamond necklaces set round stones along a gentle bend, most of them graduated so the largest sits at the center. Bars, a sweeping cross and open frames make up the range. Metal and total weight are set per listing, and 1 carat appears as an option across the board.

Lab-Grown Diamond Twisted NecklacesWhy the curve matters
Straight bars tend to tip sideways; a bowed bar hugs the neckline and hangs level. Graduated stones, small at the ends and larger in the middle, pull attention toward the middle of the arc, which keeps a curved lab-grown diamond bar necklace balanced even on a fine chain.
Bar, cross or frame
- Curved bar: the clean, smile-shaped line, prong set or bar set.
- Curved frame pendant: an open U or halo outline that hangs from a bail.
- Curved cross: arms that sweep instead of meeting at right angles.
Total weight and metal
Most designs run from about 0.35 to 3 carats total weight, and several go higher. Gold comes in 10K or 14K, in white, yellow or rose. Silvadium, a sterling silver made to resist tarnish, is the lighter-priced choice. Yellow gold gives the arc a warm outline; white gold turns the row into a single bright stroke.
Layering and care
A curved bar pairs well with a plain chain an inch or two longer, since the arc stays distinct at the base of the neck. Undo the clasp before pulling the necklace over your head, then hang it on a hook to keep the chain from tangling. Suds and an old soft toothbrush lift film from under the bar's stones.
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.
