Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a graceful arc. This semi-set three-stone engagement ring invites you to select a 9 x 4.5 mm center stone, poised to become the centerpiece of a handcrafted band forged from warm 14K yellow gold and cool 14K white gold.

The band’s artisan finish reveals subtle hammer marks beneath a satin sheen, a tactile reminder of the Brooklyn studio where it was shaped and inspected. The three-stone setting balances architectural precision with daily wearability—its low-profile design ensures comfort beneath gloves or alongside stackable bands.

Each lab-grown diamond offers clarity and brilliance without compromise, reflecting a commitment to ethical jewelry that respects both people and planet.

Ideal for those who appreciate sculptural elegance and a ring that feels as natural as it looks, this piece complements slender fingers and lends a refined elongation to the hand’s silhouette.

Should you wish to adjust sizing or explore center stone options, our Brooklyn studio offers personalized consultations with thoughtful timelines tailored to your needs.
