Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its pointed ends drawing the eye along a graceful arc that feels both intimate and bold. This semi-set solitaire invites you to select a center stone that measures 7 by 3.5 millimeters, offering a slender profile that elongates the finger with quiet elegance.

Crafted from cool 14K white gold, the mounting features a refined low-profile setting designed for everyday wear. Each prong is meticulously shaped and polished in our Williamsburg studio, ensuring the band sits comfortably against the skin without catching. The subtle gleam of white gold complements the marquise’s dramatic shape, balancing modern geometry with soft light play.

Our commitment to sustainability is reflected in the option to pair this setting with a lab-grown diamond, offering clarity and brilliance with a lighter environmental footprint.

Ideal for those who appreciate a ring that feels both personal and practical, this solitaire setting suits slender to medium finger sizes and layers beautifully with stackable bands. Its low profile makes it glove-friendly and unobtrusive for daily life.

Should you need resizing or prefer a custom finish, our Brooklyn studio offers personalized consultations to ensure the ring fits your hand perfectly.
