Lab-Grown Diamond Engagement Ring

Sunlight catches the pointed elegance of a marquise diamond, its elongated shape casting a subtle, confident silhouette on the hand. This semi-set halo engagement ring foundation in warm 18K rose gold frames a 6 x 3.5 mm center stone with a delicate halo setting, designed to amplify brilliance while maintaining a sleek, modern-minimal profile.

Crafted in Williamsburg, Brooklyn, the band’s smooth finish and low-profile setting ensure comfort for daily wear, while the halo’s precise pavé work adds structured clarity without excess. Each piece undergoes meticulous hand inspection to meet exacting standards of craftsmanship and durability.

Choosing a lab-grown diamond here reflects a commitment to ethical jewelry, reducing environmental impact without compromising on visual purity or sparkle.

The slender rose gold band complements slender to medium finger sizes gracefully, and its low profile makes it ideal for stacking or pairing with a wedding band. The semi-set design invites you to select a marquise center stone that resonates with your personal vision.

Resizing is available to ensure the ring fits comfortably, and our studio offers personalized guidance throughout the design process.
