Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it reveals a striking balance of drama and elegance—its pointed ends drawing the eye along the finger’s natural line. This semi-set three-stone ring invites you to choose a center stone measuring 9 by 4.5 millimeters, framed by two smaller companions that enhance its architectural grace.

Crafted from 10K white gold, the band is shaped with a subtle comfort fit, polished to a satin sheen that complements the diamond’s brilliance without overwhelming it. The artisan workshop finish ensures each prong is meticulously formed to cradle your stone securely while maintaining a low-profile setting that slips easily beneath gloves or daily wear.

Our commitment to sustainability is reflected in the lab-grown diamond option, offering clarity and sparkle with a reduced environmental footprint.

This design suits those who appreciate a statement piece that remains wearable—its slender band and balanced proportions harmonize with slender or average finger sizes, and the three-stone layout lends itself well to stacking with wedding bands or delicate accent rings.

Should you need resizing, our in-house jewelers in Williamsburg provide precise adjustments to ensure a perfect fit without compromising the ring’s integrity.
