Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, dramatic shadow that feels both bold and intimate. This semi-set engagement ring invites you to select a center stone that measures 12 by 6 millimeters, its tapered points drawing the eye along the finger with a quiet elegance.

Crafted from 18K white gold, the mounting is shaped with a refined low-profile bezel setting that cradles the stone securely while maintaining a sleek, comfortable fit. The band’s smooth finish and subtle taper ensure it rests naturally against the hand, ideal for daily wear or stacking with complementary bands.

Each piece is meticulously finished in our Williamsburg studio, where artisan hands polish and inspect every curve to meet exacting standards. The choice of a lab-grown diamond center reflects a commitment to ethical jewelry—minimizing environmental impact without compromising brilliance or clarity.

This solitaire silhouette suits those who appreciate architectural grace paired with modern minimalism. Its slender form elongates the finger, while the low-profile setting slips easily beneath gloves or sleeves. The semi-set design offers flexibility to personalize your stone selection with expert guidance.

Should you need resizing or prefer a custom adjustment, our Brooklyn studio offers attentive, pressure-free consultations to ensure your ring fits seamlessly.
