Lab-Grown Diamond Engagement Ring

Imagine the subtle elegance of a marquise diamond, its elongated silhouette catching light with a quiet, tapered brilliance. This semi-set engagement ring foundation in 10K white gold offers a sleek, low-profile frame designed to showcase a 7 x 3.5 mm marquise center stone, accented delicately to enhance its refined shape.

Crafted in Williamsburg, the band is meticulously finished for a smooth, comfort fit that sits close to the finger—ideal for daily wear without catching or shifting. The setting’s precision ensures the stone will be secure while maintaining a streamlined profile that layers effortlessly with other bands.

Each piece reflects our commitment to ethical jewelry, featuring a lab-grown diamond option that balances clarity and sustainability without compromise.

Its slender silhouette suits hands that appreciate subtle drama and architectural grace, especially flattering on slender fingers or when paired with stackable rings. The semi-set design invites your choice of center stone, allowing a personalized expression of style and meaning.

Should you need resizing, our Brooklyn studio offers expert adjustments to ensure a perfect fit, crafted with care and attention to detail.
