Lab-Grown Diamond Engagement Ring

Imagine the delicate silhouette of a marquise diamond, its elongated shape catching light like a whispered secret across your hand. This three-stone semi-set ring in 10K white gold frames a 10 x 5 mm marquise center with two gently tapering side stones, creating a quiet dance of brilliance and shadow.

Crafted with a low-profile setting, the band’s smooth comfort fit ensures it sits close to the finger, ideal for daily wear without catching. Each prong is meticulously finished by hand in our Williamsburg studio, where precision meets subtle artistry in every curve and angle.

Our diamonds are lab-grown, offering clarity and sparkle with a mindful footprint—reflecting a commitment to ethical jewelry without compromise.

This design suits those who appreciate a refined statement: the marquise shape elongates the finger, while the three-stone arrangement adds narrative depth, perfect for stacking or wearing solo. Its slender band and secure setting make it glove-friendly and easy to pair with wedding bands.

Should you need resizing, our in-studio experts handle adjustments with care, ensuring the ring fits as naturally as a second skin.
