Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a 12 x 6 mm marquise diamond, casting a slender, confident silhouette across the hand. This semi-set three-stone engagement ring in 18K white gold frames the center stone with two delicate side gems, emphasizing architectural clarity and modern minimalism.

Crafted in Williamsburg, the band’s smooth, comfort-fit shank balances presence with wearability, designed for daily life without bulk. The low-profile setting keeps the stones secure while allowing light to dance freely through the facets, enhancing the marquise’s signature tapered drama.

Each diamond is lab-grown, offering a transparent origin and a smaller environmental footprint without sacrificing brilliance or purity. The cool white gold complements the icy clarity of the stones, creating a cohesive, refined look.

This ring suits those who appreciate structured elegance and a statement that elongates the finger, pairing well with stackable bands or worn solo. Its semi-set nature invites you to select a center diamond that matches your vision and style.
