Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of your hand as an 8 x 4 mm marquise diamond takes center stage, its tapered points framed by a delicate halo that catches light with every movement. This semi-set engagement ring foundation in 14K white gold is crafted with meticulous attention in our Williamsburg studio, where each prong is hand-finished to secure your future stone while maintaining a sleek, low-profile silhouette.

The halo setting enhances the marquise’s dramatic shape, amplifying its vintage-inspired charm without overwhelming daily wear. The band’s smooth comfort fit and modest height make it glove-friendly and ideal for stacking alongside wedding bands or personal treasures.

Our commitment to sustainability is reflected in the use of a lab-grown diamond center, offering clarity and brilliance with a lighter environmental footprint.

Designed for those who appreciate artisan craftsmanship and subtle statement, this mounting suits a range of hand sizes, especially elongating narrower fingers with its architectural form.

Should you need resizing or prefer a custom finish, our Brooklyn studio offers personalized consultations to ensure your ring fits seamlessly into your life.
