A delicate half-carat eternity band of lab-grown diamonds in alternating marquise and round cuts. The Petite Lex Marquise & Round is vintage-influenced — flush against an engagement ring, stacked for an anniversary, or worn on its own. In 14K, 18K, or platinum. US sizes 4 to 10.

Each marquise diamond is cradled in a leaf-shaped frame of metal, with a small round brilliant set between every pair. The result is a band with a quiet rhythm — pointed marquise, small round, pointed marquise, repeating. Up close it reads as fine detail; from across the room it reads as a delicate sparkle. The Petite Lex Marquise & Round works as a wedding band on its own or layered above a solitaire to add texture. Each ring is finished to your size, so carat weight and diamond count shift slightly between sizes around the 0.5 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 Lex Marquise & Round Eternity Band?
A delicate full eternity ring of lab-grown diamonds in alternating marquise and round cuts, totaling half a carat, available in 14K and 18K yellow, rose, or white gold and in solid platinum, in US sizes 4 through 10.

How are the cuts arranged?
Each marquise diamond is set in a leaf-shaped metal frame, with a small round brilliant nested between every pair of marquises. The pattern repeats around the full circumference.

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.

Will it stack with my engagement ring?
Yes. The slim, vintage-style profile sits flush against most solitaires and pairs especially well with elongated center stones — marquise, oval, 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.
