Product Description

Milgrain Marquise Lab-Grown Diamond Engagement Ring in Solid 14K Gold

Old-world detail, new-world diamond. A 1ct marquise-cut Lab-Grown Diamond center stone in a scalloped, milgrain-edged basket — the kind of setting you'd expect to find on a ring passed down through generations, not ordered off a shelf. Handcrafted to order in our Woodside, Queens workshop.

The center stone

A 1ct marquise-cut Lab-Grown Diamond — the most elongating silhouette in fine jewelry, with two dramatic points that make the stone read significantly larger than the carat weight suggests. Lab-Grown Diamonds are physically, chemically, and optically identical to mined diamonds: same hardness (10 on the Mohs scale), same refractive index, same brilliance. Grown in a controlled environment, graded by the same 4Cs as mined stones.

The vintage detail

The center stone sits in a scalloped milgrain basket — a continuous row of tiny beaded gold dots tracing the setting edge, the signature mark of early 20th-century fine jewelry. Beneath the stone, a row of .04ct Lab-Grown Diamonds lines the gallery, adding depth and sparkle visible from the side profile. A fine rope-twist texture traces the shoulders of the 2mm band — quiet, deliberate, the detail you notice on the second look. Nothing here is loud. Everything is considered.

The metal

Available in solid 14K yellow gold, 14K white gold, and 14K rose gold — all nickel-free, solid throughout, never plated or gold-filled. White gold sharpens the contrast between metal and stone for a clean, modern take on the vintage setting. Yellow gold deepens the warmth and reads closest to the antique originals this design draws from. Rose gold adds a romantic softness to the milgrain detail without losing any of the precision.

Handcrafted in New York City

Every ring is made to order by founder Dimitri in our Woodside, Queens workshop — your size, your metal, built from start to finish after you order. The milgrain edging and rope-twist shoulders are finished by hand so the detail reads cleanly under any light. Production takes 2–3 weeks from order confirmation. Ships free and fully insured anywhere in the US, backed by a lifetime warranty against manufacturing defects. Non-engraved pieces can be returned within 14 days. Questions?
