Lab-Grown Diamond Engagement Ring

Light catches the elongated points of a marquise diamond, casting a subtle, tapered glow that draws the eye along the finger’s natural line. This semi-set engagement ring in 10K white gold offers a refined foundation, ready to showcase a 12 x 6 mm marquise center stone with delicate accent details that enhance its architectural silhouette.

Crafted with a low-profile setting, the band sits close to the finger for everyday comfort and ease beneath gloves or sleeves. The cool sheen of white gold is polished to a smooth finish, ensuring a gentle feel against the skin while maintaining durability for daily wear. Each mounting is meticulously inspected in our Williamsburg studio to meet exacting standards of balance and fit.

Our diamonds are lab-grown, reflecting a commitment to ethical sourcing and environmental mindfulness without compromising on clarity or brilliance.

The elongated marquise shape suits hands that appreciate a blend of drama and elegance, especially flattering on slender fingers or those seeking a ring that visually lengthens the hand. The semi-set design invites you to select a center stone that resonates personally, making this ring a truly bespoke expression.

Resizing is available to ensure a precise fit, with care instructions provided to maintain the metal’s luster and the setting’s integrity over time.
