Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of your finger, crowned by a marquise diamond that captures light with its tapered, dramatic silhouette. This semi-set engagement ring invites you to select a center stone that measures 9 by 4.5 millimeters, offering a striking balance between presence and elegance.

Handcrafted in warm 18K rose gold, the mounting features a delicate yet secure solitaire setting, shaped and polished in our Williamsburg studio. The slender band curves gently for a comfort fit, designed to sit low and unobtrusively, making it ideal for daily wear or stacking with complementary bands.

Each piece reflects our commitment to ethical jewelry: the setting awaits your choice of a lab-grown marquise diamond, known for its clarity and sustainable origin. This approach reduces environmental impact without compromising brilliance or character.

Its refined profile suits those who appreciate artisan craftsmanship and a modern silhouette that elongates the hand gracefully. The ring’s low-profile setting ensures it slips easily under gloves or sleeves, perfect for an active lifestyle.

Should you need resizing, our Brooklyn studio offers precise adjustments to ensure a perfect fit without disrupting the ring’s delicate balance. Typical lead times accommodate thoughtful customization and expert finishing.
