Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a 12 x 6 mm marquise diamond, it draws the eye along its tapered points, creating a subtle drama that feels both refined and distinctive. This solitaire semi-set ring offers a streamlined foundation crafted from 18K white gold, designed to cradle your chosen stone securely while maintaining a low profile that slips comfortably beneath daily gloves or sleeves.

The band’s polished finish and precise setting reflect careful handwork in our Williamsburg studio, where each piece undergoes meticulous inspection to ensure durability and wearability. Its slender shank balances presence with ease, making it an ideal choice for those seeking a ring that harmonizes with everyday movement without catching or lifting.

Choosing a lab-grown diamond for this setting aligns with a commitment to ethical jewelry—minimizing environmental impact while delivering exceptional clarity and brilliance. The marquise shape’s elongated form naturally complements slender fingers, and the semi-set design invites you to select a center stone that matches your personal vision.

Resizing is straightforward within our Brooklyn studio, allowing for a tailored fit that feels effortless on the hand. Whether worn solo or paired with a wedding band, this ring’s silhouette supports stacking without overwhelming.
