Lab-Grown Diamond Engagement Ring

Imagine the gentle curve of a marquise diamond, its tapered points catching light like whispered secrets along a quiet Brooklyn afternoon. This semi-set halo engagement ring foundation invites your choice of a 13 x 6 mm marquise stone, framed by a delicate halo that amplifies its elongated elegance with subtle brilliance.

Crafted in cool platinum, the mounting balances strength with refined grace, its low-profile setting designed for everyday wear without sacrificing sparkle. Each prong is meticulously shaped and polished in our Williamsburg studio, ensuring a secure hold and a smooth feel against the skin.

Our commitment to ethical jewelry shines through the use of lab-grown diamonds, offering clarity and fire with a lighter environmental footprint. This ring’s slender band and modest height make it ideal for those who favor comfort and versatility, easily stacking with wedding bands or worn solo for understated sophistication.

Should you need resizing or prefer a custom finish, our Brooklyn artisans accommodate adjustments with care and precision, typically within a few weeks. Whether you visit us in Williamsburg or design remotely, this semi-set halo ring is a canvas for your personal story.
