Lab-Grown Diamond Engagement Ring

The elongated silhouette of the 7 x 3.5 mm marquise diamond captures light with a subtle, tapered brilliance that draws the eye along the finger’s natural line. This solitaire semi-set ring offers a refined foundation in 18K rose gold, designed to cradle your chosen stone securely while maintaining a low-profile presence.

Crafted in Williamsburg, Brooklyn, the band’s smooth finish and precise setting ensure comfort for daily wear, slipping easily beneath gloves or alongside stackable rings. The mounting’s streamlined design balances technical assurance with understated elegance, making it a versatile choice for those who value both form and function.

Each lab-grown diamond reflects a commitment to ethical sourcing and sustainability, offering clarity and sparkle without compromise. The semi-set format invites you to select a marquise stone that resonates personally, allowing for a truly custom expression.

Ideal for hands that appreciate architectural grace, this setting complements the marquise’s distinctive shape, elongating the finger while remaining unobtrusive. Resizing is available to ensure a precise fit, with care instructions tailored to preserve the metal’s warm hue and the stone’s brilliance.
