Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it reveals a striking balance of drama and refinement—an elegant statement poised to frame your hand with subtle distinction.

This semi-set solitaire ring features a 10K yellow gold band crafted for everyday wear, its low-profile mounting designed to sit close to the finger without sacrificing comfort. The setting’s precision ensures the 9 x 4.5 mm marquise center stone will be securely held while allowing maximum light to enhance its signature brilliance.

Each piece is meticulously finished in our Williamsburg studio, where expert hands polish and inspect every curve and prong to meet exacting standards. The warm glow of yellow gold complements the diamond’s fiery facets, creating a harmonious contrast that feels both modern and enduring.

Our lab-grown diamonds offer a clear ethical advantage, cultivated with minimal environmental impact and no compromise on clarity or sparkle.

Ideal for those who appreciate a sleek silhouette that layers effortlessly with other bands or stands confidently alone, this ring’s streamlined profile is glove-friendly and designed for daily life.

Should you need a custom fit, resizing is handled with care to preserve the ring’s integrity and comfort.
