Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its pointed ends tracing a delicate arc that seems to cradle the hand. This three-stone semi-set engagement ring in 18K yellow gold offers a warm embrace, the slender band polished to a soft glow that complements the stone’s dramatic shape without overwhelming it.

Each element is crafted in our Williamsburg studio, where the low-profile setting is designed for everyday wear—secure yet unobtrusive, allowing the marquise’s signature sparkle to dance freely. The band’s gentle curve and comfort fit ensure it sits naturally, whether worn alone or stacked with other favorites.

Our diamonds are lab-grown, offering the clarity and fire of mined stones with a lighter environmental footprint, reflecting a quiet commitment to ethical jewelry. The semi-set design invites you to select a center stone that resonates personally, making this ring a truly bespoke expression.

Ideal for those who appreciate a blend of classic romance and modern craftsmanship, this ring suits slender to medium finger shapes, elongating the hand with its architectural grace. Its streamlined profile slips easily beneath gloves or daily wear.

Should you need resizing or guidance on stone selection, our Brooklyn studio offers personalized consultations to ensure a flawless fit and finish.
