Lab-Grown Diamond Engagement Ring

Soft light catches the gentle curves of a 5 x 5 mm cushion diamond, its rounded corners and subtle facets inviting a quiet intimacy. This semi-set three-stone platinum ring offers a refined foundation, ready to cradle your chosen center stone with a low-profile setting that rests close to the finger.

Handcrafted in our Williamsburg studio, the platinum band is polished to a satiny finish, balancing durability with a smooth comfort fit that suits daily wear. The three-stone arrangement frames the center with delicate side settings, enhancing sparkle without overwhelming the hand’s natural grace.

Each lab-grown diamond reflects a commitment to ethical sourcing and environmental mindfulness, embodying clarity without compromise. The ring’s modest height and slender shank make it ideal for stacking or wearing alongside a wedding band, while its secure prong setting ensures ease of movement and glove-friendly wear.

Should you wish to adjust the fit, resizing is available through our in-studio service, tailored to your comfort. Lead times for custom center stones vary, and we’re happy to guide you through selecting the perfect cushion cut to complete this romantic design.
