Lab-Grown Diamond Engagement Ring

Sunlight catches the soft, rounded corners of a 12 x 12 mm cushion diamond, its halo setting poised to amplify every flicker of light. This semi-set engagement ring foundation invites your choice of a center stone, framed by a delicate halo that enhances the gem’s gentle glow.

Crafted from 18K white gold, the band is meticulously shaped for a smooth, comfort fit that rests lightly against the skin. The halo setting is low-profile yet intricate, designed in our Williamsburg studio with artisan precision to balance sparkle and everyday wearability.

Each piece reflects our commitment to ethical jewelry: the setting is made exclusively for lab-grown diamonds, reducing environmental impact without compromising brilliance.

Ideal for those who appreciate a classic cushion shape’s soft vintage appeal, this ring’s silhouette complements slender to medium finger sizes and layers beautifully with stackable bands. Its subtle height ensures it slips easily under gloves or sleeves.

Should you need resizing or guidance on selecting the perfect center stone, our Brooklyn studio offers personalized consultations to ensure a seamless process.
