Lab-Grown Diamond Engagement Ring

Soft light filters through the gently rounded corners of a 5 x 5 mm cushion diamond, its subtle glow poised to catch the eye from every angle. This three-stone semi-set invites your choice of center gem, framed by two delicate side stones that balance presence with quiet elegance.

Crafted in cool, enduring platinum, the mounting features a refined low-profile setting that rests comfortably against the finger, designed for everyday wear without sacrificing grace. Each prong is hand-finished in our Williamsburg studio, ensuring secure hold and a polished surface that catches light with a whisper of brilliance.

Our commitment to lab-grown diamonds means this ring carries a clarity and ethical transparency that honors both the earth and your values. The cushion shape’s soft, vintage-inspired facets lend a romantic glow, ideal for those drawn to a blend of classic warmth and modern refinement.

Its balanced silhouette suits a variety of hand shapes and sizes, while the three-stone design offers versatility—wear it solo or layered with stackable bands for a personalized statement. The low-profile setting also makes it glove-friendly, perfect for daily life in Brooklyn’s changing seasons.

Should you need resizing or prefer a custom center stone, our studio offers personalized consultations to ensure a flawless fit and finish. Typical lead times reflect our artisanal approach, with every piece crafted to order.
