Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate shadow that dances along the warm blush of 14K rose gold. This three-stone semi-set engagement ring invites you to select a center stone that will become the heart of a handcrafted piece, shaped by expert artisans in our Williamsburg studio.

Each band is meticulously formed from 14K rose gold, its subtle pink hue polished to a soft glow that complements the marquise’s tapered drama. The setting’s low profile ensures everyday comfort, while the three-stone design balances visual intrigue with wearability, allowing for graceful stacking or solo elegance.

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

Designed for those who appreciate refined craftsmanship and a ring that feels as natural on the hand as it looks, this semi-set invites personal choice in stone size and cut, with a secure setting tailored to the 6 x 3 mm marquise shape.
