Silver Infinity Necklaces with Lab-Grown Diamonds, grown in light.
A figure eight that catches the light. Each infinity necklace in silver here hangs a looped pendant set with lab-grown diamonds. Some loops are lined with pavé, some hold a single prong-set stone, and others fold the symbol into a heart, a cross or a teardrop. The product page sets the total carat weight.

Pavé loop or single stone
A pavé loop is lined with tiny round lab-grown diamonds on a single curve or on both, so the whole symbol glints. A solitaire design sets one stone where the curves meet or at the top of an upright loop, and the polished metal does the rest. One design swaps the round stone for a bezel-set pear.
Infinity with a second symbol
Several pendants pair the loop with another shape: a heart with a vertical row of stones, a cross with prong-set arms, or a teardrop outline. These read as a single motif from across a room and show the infinity detail up close.
How much sparkle
Most designs offer total weights from about 0.5 to 3 ct tw, and some go up to 6 ct tw. That number counts all the lab-grown diamonds in the pendant together. Prices start under $300 at the smallest option, with many near $420.
Wearing silver every day
The chain and pendant are Silvadium, sterling silver blended to resist tarnish. Take the necklace off to shower or swim, fasten the clasp before storing so the chain doesn't knot, and polish with a soft cloth. A layered look works well with a shorter plain chain above the pendant.
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.
