Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its pointed ends drawing the eye along a delicate arc of brilliance. This semi-set five-stone engagement ring foundation in 10K white gold invites your choice of a 6 x 3 mm center stone, ready to become a personal emblem of quiet devotion.

Crafted with a low-profile setting, the band’s slender form balances subtlety with presence, designed for comfortable daily wear. Each prong is meticulously shaped and polished in our Williamsburg studio, ensuring the mounting cradles your chosen diamond securely while allowing maximum light to animate its facets.

Our commitment to sustainability is reflected in the lab-grown diamond clarity this ring is designed to showcase—ethical jewelry that honors both beauty and conscience.

The elongated marquise shape naturally elongates the finger, pairing gracefully with slender hands or stacking effortlessly alongside complementary bands. Its refined silhouette slips easily beneath gloves or sleeves, making it a versatile choice for everyday elegance.

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