Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of the marquise diamond, its tapered points drawing the eye along the finger with a subtle, sculptural grace. This semi-set three-stone ring foundation in warm 18K yellow gold invites your choice of center stone, designed to showcase an 8 x 4 mm marquise with architectural poise.

Hand-forged in our Williamsburg studio, the band’s gently rounded profile balances presence with comfort, while the three-stone setting offers a harmonious frame that enhances the diamond’s natural brilliance. Each prong is meticulously shaped and polished to secure the stone low against the finger, creating a refined, low-profile silhouette that suits daily wear.

Crafted exclusively with lab-grown diamonds, this piece reflects a commitment to ethical sourcing and environmental mindfulness without compromise on clarity or fire.

The slender band fits comfortably beneath gloves and layers seamlessly with other stackable rings, ideal for those who appreciate subtle statement and versatility. Its proportions flatter a range of hand sizes, especially elongating the finger’s line with the marquise’s distinctive shape.

Should you need adjustments, resizing is available to ensure a perfect fit, with attentive care guidance provided for lasting brilliance.
