Lab-Grown Diamond Eternity Necklaces, grown in light.
A closed ring of stones at the throat. An eternity necklace lines an open circle with round lab-grown diamonds, unbroken, so the line of light has no start or end. Choose a thin, small, wide or open circle, then the metal and total carat weight; every design offers 0.5 to 2 ct tw.

Thin, small or wide circle
- Thin circle: shared prongs let the stones nearly touch, for a fine continuous line.
- Small circle: compact, sitting higher at the collarbone.
- Wide circle: a broader ring of stones that reads from farther away.
- Open circle: more space in the middle and a lighter look.
Total weight on a circle
Carat options here add up the whole circle. At 0.5 ct tw the eternity pendant necklace is delicate; at 1.5–2 ct tw each stone is big enough to throw its own flash. Because the weight is shared, even the top sizes stay refined.
Choosing gold or silver
Gold comes in 10K or 14K, in white, yellow or rose. Silvadium, a sterling silver crafted to resist tarnish, is the lighter-priced choice. White metals keep the circle icy; yellow and rose gold give it a warmer edge.
Wearing an eternity pendant
The circle shape is a familiar anniversary and milestone gift, and it layers well with a plain chain. Prong-set stones can loosen after hard knocks, so take the pendant off for sports and check the prongs now and then. A soft brush and a little dish soap keep the prongs clear.
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.
