Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate dance of light that seems to stretch across the finger. This three-stone semi-set engagement ring in 10K yellow gold frames a 7 x 3.5 mm marquise center with two gently curving side stones, creating a subtle narrative of connection and grace.

Crafted with a low-profile setting, the band’s warm yellow gold is hand-finished in Williamsburg to a smooth comfort fit that slips easily beneath a glove or alongside stackable bands. Each prong is meticulously shaped to cradle the marquise securely while allowing maximum light to pass through the stone’s tapered points, enhancing its signature brilliance.

Our commitment to ethical jewelry shines through the use of a lab-grown diamond, offering clarity and sparkle with a lighter environmental footprint. This ring’s slender silhouette suits hands that appreciate refined elegance without excess bulk, ideal for daily wear and those who favor a delicate yet confident statement.

Should you wish to adjust the fit, resizing is available through our Brooklyn studio without compromising the ring’s integrity. The semi-set design invites you to select a center stone that resonates personally, making this piece uniquely yours.
