Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, graceful shadow across the hand. This three-stone semi-set engagement ring frames a 9 x 4.5 mm marquise center with two delicately matched side stones, each carefully positioned to enhance the stone’s tapered drama.

Crafted from warm 18K yellow gold, the band is shaped and polished in our Williamsburg studio to a smooth comfort fit, designed for everyday wear without catching or discomfort. The low-profile setting keeps the stones secure while maintaining a refined silhouette that slips easily beneath gloves or alongside stackable bands.

Each ring is finished with meticulous hand inspection, ensuring the prongs cradle the marquise securely while allowing maximum light to animate the diamond’s facets. The semi-set design invites you to select a lab-grown diamond that meets your clarity and color preferences, marrying personal choice with expert craftsmanship.

Lab-grown diamonds offer a clear ethical advantage, reducing environmental impact without compromising brilliance or durability.

This ring suits those who appreciate architectural elegance with a touch of vintage flair, especially flattering on slender fingers where the marquise shape elongates the hand. Its balanced proportions and comfort fit make it a versatile piece for daily life and special moments alike.
