Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of the marquise diamond, casting a slender, graceful shadow across the hand. This three-stone semi-set engagement ring features an 8 x 4 mm marquise center, its pointed ends drawing the eye along the finger’s natural line.

Crafted from warm 18K yellow gold, the band is shaped and polished in our Williamsburg studio to a smooth, comfort fit that feels as natural as it looks. The setting’s artisan detail—secure prongs and a low-profile gallery—ensures everyday wearability without sacrificing the diamond’s dramatic presence.

Each lab-grown diamond is selected for clarity and brilliance, reflecting our commitment to sustainable, ethical jewelry without compromise. The three-stone design offers a narrative of past, present, and future, balanced with a refined silhouette that complements slender or average finger shapes.

Its modest height and tapered form make this ring glove-friendly and ideal for stacking with other bands or wedding rings. Should you wish to adjust sizing, our in-house jewelers provide expert resizing with care and precision.
