Gold Lab-Grown Diamond Necklaces, grown in light.
A pendant that rests at the collarbone. Most gold necklaces here are pendants built around round lab-grown diamonds, ranging across lone solitaires, halos, graduated curves and open hearts; some are tennis or station necklaces. On the product page you choose white, yellow or rose gold, 10K or 14K, and a total weight, commonly 1 to 3 ct tw.

Pendant, tennis or station
- Pendants: one focal shape on a chain, from a halo or solitaire to a cross, heart or S-curve.
- Tennis necklaces: lab-grown diamonds set all along the chain for a continuous line.
- Station necklaces: stones spaced along the chain, lighter in look and easy to layer.
Total weight and how it reads
Under 1 ct tw, a pendant is a quiet point of light suited to daily wear. Between 1 and 3 ct tw the stones are clearly visible across a table. Many designs continue to 5 or 6 ct tw for a bold focal piece. Graduated designs place the largest stone at the center, so most of the weight sits at the lowest point.
10K or 14K gold necklaces
Most designs come in 10K or 14K; a few also offer 18K. 10K wears hard and keeps a fine chain from stretching. 14K gold necklaces give a fuller yellow or rose tone, and 18K, where offered, is the warmest. White gold gives colorless stones a cool, bright frame.
Chain care and clasps
Put perfume and lotion on first, then the necklace. Overnight a chain twists into kinks, so unclasp it before bed and hang it from a hook or stretch it out in a drawer. A brief dip in sudsy water, with a gentle bristle behind the pendant, clears the back of the 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.
