Lab-Grown Diamond Engagement Ring

Imagine the gentle curve of a hand adorned with a marquise diamond, its elongated silhouette catching light like a whispered secret. This semi-set three-stone engagement ring invites you to choose a 12 x 6 mm marquise center, poised to elongate the finger with elegant drama.

Crafted in 18K white gold, the mounting balances refined strength with a delicate profile. Each prong is hand-finished to cradle the stone securely while maintaining a low profile that slips comfortably beneath gloves or daily wear. The side stones frame the center with subtle brilliance, enhancing the ring’s poetic geometry without overwhelming it.

Our commitment to sustainability shines through the lab-grown diamond option, offering clarity and sparkle with a lighter environmental footprint.

Designed for those who appreciate a ring that feels as natural as it looks, this piece suits slender to medium fingers and layers beautifully with stackable bands. Its comfort fit and modest height make it a seamless companion for everyday life.

Should you need resizing, our Brooklyn studio handles adjustments with care, ensuring your ring fits perfectly without compromising its delicate structure.
