Lab-Grown Diamond Engagement Ring

Imagine the subtle drama of a marquise diamond, its elongated silhouette catching light with a refined, architectural grace. This semi-set engagement ring foundation in 18K yellow gold offers a sleek, modern-minimal frame designed to highlight a 7 x 3.5 mm marquise center stone, surrounded by delicate accent settings that enhance clarity and structure without distraction.

Crafted in Williamsburg, the band is hand-finished to a smooth comfort fit, balancing low profile wearability with confident presence. The setting’s precise prongs cradle the stone securely while allowing maximum light to animate its facets, a testament to meticulous local craftsmanship.

Each diamond chosen for this ring is lab-grown, reflecting a commitment to ethical jewelry that reduces environmental impact without compromising brilliance or purity.

Ideal for those who appreciate clean lines and architectural form, this ring suits slender to medium finger shapes and layers effortlessly with stackable bands or stands strikingly alone. Its low profile makes it glove-friendly and practical for daily wear.
