Lab-Grown Diamond Engagement Ring

Imagine the subtle drama of a marquise diamond, its elongated silhouette catching light with a confident gleam, poised to crown your story. This semi-set halo engagement ring foundation in warm 14K rose gold offers a structured yet modern-minimal frame, designed to elevate a 7 x 3.5 mm marquise center stone with clarity and precision.

Crafted in Williamsburg, the band’s smooth finish and delicate halo setting balance architectural lines with gentle curves, creating a low-profile presence that wears comfortably beneath gloves or alongside stackable bands. Each piece is meticulously inspected to ensure the rose gold’s soft blush complements the diamond’s fiery facets without distraction.

Choosing a lab-grown diamond here reflects a quiet commitment to sustainability and ethical sourcing, marrying beauty with conscience in every detail.

The ring’s semi-set nature invites personal choice, allowing you to select a marquise stone that resonates with your vision while benefiting from expert craftsmanship in the mounting. Its slender band and halo design suit hands seeking a refined statement that remains practical for daily wear.
