Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate shimmer that seems to stretch beyond the hand. This three-stone semi-set engagement ring in 18K yellow gold frames a 12 x 6 mm marquise center, its pointed ends drawing the eye with graceful drama.

Crafted in Williamsburg, the band’s warm gold hue is hand-polished to a soft glow, complementing the diamond’s glassy facets. The three-stone setting balances presence with wearability, designed with a low profile that slips comfortably beneath gloves or daily wear. Each prong is meticulously finished to secure the stone while allowing light to dance freely across its surface.

Our diamonds are lab-grown, offering clarity and brilliance with a mindful approach to sustainability and ethical sourcing.

This ring suits those who appreciate a blend of architectural elegance and romantic symbolism, its shape elongating the finger and pairing beautifully with stackable bands or a simple wedding band. The semi-set design invites you to select a center stone that reflects your unique story.

Resizing is available to ensure a perfect fit, with care instructions provided to maintain the ring’s luminous finish over time.
