Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a delicate halo of shimmering pavé. This semi-set engagement ring foundation in warm 18K rose gold invites your choice of a 10 x 5 mm center stone, ready to become a personal emblem of commitment.

Handcrafted in our Williamsburg studio, the band’s subtle curve and low-profile halo setting balance presence with everyday wearability. The rose gold’s soft blush complements the marquise’s dramatic shape, while expert finishing ensures a smooth comfort fit that slides easily beneath gloves or alongside stackable bands.

Each ring begins with a lab-grown diamond, chosen for its clarity and ethical provenance, reflecting a commitment to sustainability without compromise on brilliance.

Ideal for those who appreciate architectural elegance with a feminine warmth, this mounting suits slender to medium finger sizes, enhancing the hand’s natural lines without overwhelming.

Should you need adjustments, resizing is handled delicately in-house to maintain the ring’s integrity and finish.
