Three carats of round-brilliant lab-grown diamonds, set around the full ring. The Petite Melrose Round is the most classic eternity silhouette — flush against an engagement ring, stacked for an anniversary, or worn on its own. In 14K, 18K, or platinum. US sizes 4 to 10.

The petite proportions make this the everyday version of the round eternity band — small enough to layer with two or three more, slim enough to wear under a stack with a solitaire on top. The round brilliant cut throws white light from every angle, so the band reads bright in any lighting. Each ring is finished to your size, so carat weight and diamond count shift slightly between sizes around the 3 ct total.

Care

Clean with warm water, a drop of mild dish soap, and a soft toothbrush around the prongs; pat dry with a lint-free cloth. Remove before lifting weights, gardening, or applying lotion or sunscreen. Have the prongs inspected once a year — on a full eternity band, a single loose prong can affect both stones it holds.

FAQ

What is the Petite Melrose Round Classic Eternity Band?
A full eternity ring of prong-set round-brilliant lab-grown diamonds totaling 3 carats, available in 14K and 18K yellow, rose, or white gold and in solid platinum, in US sizes 4 through 10.

Is this a full or half eternity band?
Full eternity. The diamonds wrap the entire ring, including the section that rests against your palm.

Can a full eternity band be resized?
No. Because the diamonds cover the entire band, there is no plain metal section to add or remove. Order your exact size — half-size increments are offered from 4 to 10.

How many diamonds does this ring have?
Each ring is finished to fit your size, so the diamond count and total carat weight shift slightly between sizes around the 3 ct total. The look is uninterrupted in every size.

Will it stack with my engagement ring?
Yes. Round-brilliant eternity bands are the most universal pairing — they stack flush against any cut of center stone, from round to emerald to pear.

What's the difference between 14K, 18K, and platinum here?
14K gold (58.3% gold) is harder and more scratch-resistant in daily wear. 18K (75% gold) has a deeper color. Platinum is denser, naturally white, and never needs re-plating.
