Lab-Grown Diamond Engagement Ring

Sunlight catches the slender silhouette of a marquise diamond, its tapered points tracing a delicate arc that seems to elongate the hand with quiet elegance. This semi-set engagement ring in warm 10K rose gold offers a soft blush glow that complements the stone’s sharp geometry, creating a subtle contrast between metal and light.

Crafted in Williamsburg, the band is shaped for comfort with a gentle curve that rests naturally against the finger. The low-profile setting invites daily wear without catching, while the rose gold’s satin finish enhances the ring’s understated romance. Each piece is meticulously inspected to ensure the prongs cradle your chosen marquise securely, ready to showcase its distinctive brilliance.

Our lab-grown diamonds bring clarity and ethical transparency to this design, reflecting a commitment to sustainability without compromise. The marquise’s elongated form suits slender fingers beautifully and pairs effortlessly with stacking bands or a wedding ring, making it a versatile choice for those who appreciate refined craftsmanship and modern wearability.

Should you wish to adjust the fit, resizing is available to maintain comfort and balance. Lead times are tailored to your custom stone selection, ensuring a personal experience from start to finish.
