Lab-Grown Diamond Engagement Ring

When light catches the elongated points of a marquise diamond, it creates a striking silhouette that draws the eye along the finger’s natural line. This semi-set engagement ring offers a 12 x 6 mm marquise center, poised to showcase your chosen stone with architectural clarity and modern restraint.

Crafted from 10K white gold, the mounting features delicate accent settings that enhance the diamond’s brilliance without overwhelming its sleek profile. The low-profile design ensures comfortable daily wear, while the polished finish reflects subtle light, emphasizing the ring’s clean geometry.

Each piece is meticulously finished in our Williamsburg studio, where expert hands inspect every facet and prong to ensure durability and refined detail. The use of lab-grown diamonds aligns with a commitment to ethical jewelry, reducing environmental impact without compromising on clarity or fire.

This ring suits those who appreciate structured elegance and a confident statement that remains understated. Its shape elongates the finger, while the semi-set style invites you to select a center stone that resonates personally. The mounting’s slim band and modest height make it ideal for stacking or pairing with a wedding band.

Resizing is available to ensure a perfect fit, with care instructions provided to maintain the metal’s luster and the stone’s sparkle over time.
