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 complements the natural lines of the hand. This semi-set engagement ring foundation awaits your choice of a 7 x 3.5 mm marquise center, designed to showcase the stone’s distinctive tapered drama with modern-minimal clarity.

Crafted in 14K rose gold, the mounting balances warmth with subtlety, its clean lines and precise accents framing the center stone without distraction. The low-profile setting ensures daily wearability, slipping comfortably beneath gloves and layering seamlessly with other bands. Each ring is meticulously finished and inspected in our Williamsburg studio, where expert hands refine every detail.

Our commitment to lab-grown diamonds reflects a quiet dedication to ethical jewelry, offering clarity and brilliance without compromise. The semi-set design invites personalization, making it ideal for those who appreciate thoughtful customization and a contemporary aesthetic.

Sized to fit a variety of hand shapes, this mounting suits anyone seeking a refined statement that feels as natural as it looks striking. Resizing is available to ensure a perfect fit, with care instructions provided to maintain its polished surface over time.
