Lab-Grown Diamond Engagement Ring

Imagine the quiet sparkle of a square lab-grown diamond, its clean lines catching light like a secret whispered in a Brooklyn loft. This semi-set five-stone engagement ring foundation in polished platinum frames a 10 x 10 mm center stone with subtle grace, inviting your choice of a square-cut gem to anchor its geometry.

Crafted with a low-profile setting, the band’s smooth platinum surface offers a comfortable fit that rests gently against the skin, designed for everyday wear without fuss. Each prong is meticulously finished to secure the stones while allowing maximum light to animate their facets, a testament to careful handwork and rigorous inspection in our Williamsburg studio.

Choosing a lab-grown diamond here means embracing clarity and brilliance with a lighter environmental footprint, reflecting a commitment to ethical jewelry without compromise.

The ring’s architectural square shape lends itself to those who appreciate modern geometry and refined structure, while the five-stone layout adds a poetic rhythm of light and shadow. Its balanced width and low profile make it ideal for stacking or wearing solo, fitting seamlessly into a life that values both elegance and ease.
