Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated facets of an emerald-cut diamond, casting a serene, glassy glow that feels both architectural and intimate. This three-stone semi-set engagement ring in platinum offers a refined foundation for a 10 x 8 mm emerald-shaped center stone, designed to sit close to the finger with a low-profile setting that balances presence and practicality.

Crafted in platinum, the mounting features clean lines and secure prongs that cradle the center stone while allowing light to travel freely through its step-cut planes. The band’s subtle width and comfort fit ensure it wears smoothly beneath gloves or alongside other stackable rings, making it a versatile choice for daily life.

Each piece is meticulously finished and inspected in our Williamsburg studio, where precision meets quiet strength. The lab-grown diamond option reflects a commitment to ethical jewelry, reducing environmental impact without compromising brilliance or clarity.

Ideal for those who appreciate architectural elegance paired with understated durability, this ring suits hands that favor elongated shapes and a sleek silhouette. The semi-set design invites you to select a center stone that resonates personally, ensuring a truly custom expression.

Resizing is available to accommodate your unique fit, and our team is happy to guide you through care recommendations to maintain the ring’s polished surface and secure setting.
