Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, graceful shadow across the hand. This semi-set halo engagement ring frames a 9 x 4.5 mm marquise stone, known for its tapered drama and ability to visually lengthen fingers with elegant poise.

Crafted from 18K white gold, the band is shaped and polished in our Williamsburg studio to a smooth comfort fit, designed for daily wear without bulk. The halo setting, ready to embrace your chosen center stone, is meticulously hand-set with pavé diamonds that enhance brilliance while maintaining a low profile.

Each ring undergoes rigorous inspection to ensure the precision of prong placement and the seamless finish that defines artisan craftsmanship. The use of lab-grown diamonds reflects a commitment to ethical jewelry, reducing environmental impact without compromising on clarity or sparkle.

Its slender silhouette suits those who appreciate refined geometry and subtle statement pieces. The low-profile halo and comfort-fit band make it ideal for stacking or wearing alongside a wedding band, while the semi-set design invites personal choice in selecting the perfect marquise stone.

Resizing is straightforward and handled with care in-studio, ensuring the ring maintains its structural integrity and finish. Typical lead times accommodate custom requests, allowing for a thoughtful, pressure-free design experience.
