Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of the marquise diamond, casting a slender, luminous shadow across the hand. This solitaire semi-set invites you to select a center stone that echoes your personal story, framed by a warm 14K rose gold band that softens the sharp geometry with its gentle blush.

Crafted in our Williamsburg studio, the band is hand-shaped and polished to a satin finish that feels smooth against the skin, designed for daily wear without fuss. The low-profile setting balances presence with comfort, allowing the marquise’s pointed ends to extend gracefully without catching.

Each piece reflects our commitment to sustainability through lab-grown diamonds, offering clarity and brilliance with a lighter environmental footprint. The rose gold’s subtle warmth complements a variety of skin tones, making this ring a versatile choice for those who appreciate refined artisan detail.

Ideal for slender fingers or those who favor an elegant elongation effect, this setting pairs beautifully with stacking bands or worn solo as a statement of quiet confidence. Its semi-set nature means you can collaborate with us to find the perfect marquise diamond, tailored to your vision.
