Lab-Grown Diamond Engagement Ring

Sunlight catches the sharp, architectural facets of an Asscher diamond, its step-cut clarity framed by a halo that amplifies every glint. This semi-set engagement ring invites you to select a 5 x 5 mm center stone, ready to be embraced by an 18K white gold band meticulously crafted in our Williamsburg studio.

The band’s low-profile halo setting balances presence with wearability, designed for daily life with a smooth comfort fit that rests gently against the finger. Each curve and prong is hand-finished, inspected under magnification to ensure precision and durability without excess height that might catch or snag.

Our commitment to lab-grown diamonds means your ring carries a clarity and brilliance born from sustainable innovation, reflecting a modern approach to ethical jewelry.

Ideal for those who appreciate architectural elegance paired with subtle sparkle, this ring suits slender to medium finger shapes and layers effortlessly with stackable bands or wedding bands of similar profile.

Should you need resizing, our Brooklyn studio offers expert adjustments to ensure a perfect fit without compromising the ring’s integrity.
