Lab-Grown Diamond Engagement Ring

Light catches the elongated points of a 7 x 3.5 mm marquise diamond, its tapered silhouette drawing the eye along the finger with subtle drama. This semi-set halo ring in 10K white gold offers a refined foundation, designed to cradle your chosen center stone with precision and a low-profile setting that slips comfortably beneath daily gloves and sleeves.

Crafted in Williamsburg, the band’s smooth finish and secure halo setting balance sparkle with wearability, ensuring the ring endures everyday moments without catching or discomfort. The 10K white gold provides a durable, luminous frame that complements the marquise’s glassy, elegant shape.

Each piece reflects our commitment to ethical jewelry, featuring lab-grown diamonds that reduce environmental impact while maintaining exceptional clarity and brilliance.

Its slender silhouette suits hands seeking a graceful elongation effect, pairing effortlessly with stackable bands or standing alone as a statement of modern romance. The low profile and comfort fit make it ideal for those who value both style and practicality.
