Lab-Grown Diamond Engagement Ring

Imagine the gentle elongation of a hand caught in a quiet moment, where light dances along the pointed curves of an 8 x 4 mm marquise diamond, its silhouette both bold and graceful. This semi-set solitaire invites you to select a center stone that captures your personal story, framed by a 14K white gold band that feels smooth and substantial against the skin.

Crafted with precision in Williamsburg, Brooklyn, the mounting features a low-profile setting designed for everyday wear—secure yet unobtrusive beneath gloves or layered with other bands. The polished white gold surface is meticulously finished to a soft sheen, reflecting light without glare, while the slender shank balances strength with comfort.

Each lab-grown diamond chosen for this ring carries the clarity and brilliance of natural stones, with a mindful footprint that aligns with sustainable values.

Ideal for those who appreciate architectural elegance with a whisper of vintage romance, the marquise shape visually elongates the finger, lending a refined silhouette that complements slender and broader hands alike.
