Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it draws the eye along its graceful points, evoking a quiet confidence with every glance. This semi-set halo engagement ring foundation in warm 10K rose gold frames a 12 x 6 mm center stone with a delicate circle of pavé, designed to amplify brilliance without overwhelming the finger.

Crafted in Williamsburg, the band’s slender profile and low-set halo ensure a comfortable fit that slips easily beneath gloves or alongside stackable bands. The rose gold’s subtle blush complements the marquise’s sharp geometry, marrying modern minimalism with architectural clarity. Each piece is hand-finished and meticulously inspected to meet exacting standards of polish and symmetry.

Choosing a lab-grown diamond for this setting reflects a commitment to ethical jewelry, reducing environmental impact while maintaining exceptional clarity and sparkle. The semi-set design invites you to select a center stone that resonates personally, allowing for a truly bespoke expression.

Ideal for those who appreciate structured elegance and a ring that balances statement with everyday wearability, this setting suits slender to medium finger sizes and adapts well to various marquise proportions. Resizing is available to ensure a perfect fit without compromising the band’s sleek lines.
