Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate shadow that dances like a whispered promise. This semi-set engagement ring invites you to choose a 10 x 5 mm center stone, its tapered points drawing the eye along a graceful arc framed by a halo of smaller diamonds.

Crafted from warm 14K rose gold, the band is polished to a soft glow that complements the stone’s fiery brilliance. The halo setting enhances the marquise’s natural drama while maintaining a low profile, designed for everyday wear without catching or discomfort. Each curve is hand-finished in our Williamsburg studio, ensuring a seamless balance between elegance and resilience.

Our commitment to sustainability shines through the use of lab-grown diamonds, offering clarity and sparkle with a lighter environmental footprint. This ring suits those who appreciate refined romance and a silhouette that elongates the finger, pairing beautifully with slender stacking bands or worn solo.

Should you need adjustments, resizing is handled expertly in-house to preserve the ring’s integrity and comfort fit. Lead times vary slightly depending on stone selection, but every piece is crafted with patient care.
