Under soft studio light, the 8 x 8 mm cushion-cut diamond catches the eye with its gentle, vintage-inspired glow—each facet inviting a closer look. Set in a sleek platinum band, this engagement ring balances presence with subtlety, its low-profile setting designed to sit comfortably against the finger for everyday wear.

Crafted in Williamsburg, the ring’s platinum shank is polished to a mirror finish, enhancing durability without sacrificing elegance. Accents flank the center stone, adding quiet sparkle while maintaining a streamlined silhouette that slips easily beneath gloves or alongside other bands.

Our lab-grown diamond offers a clarity and brilliance that honors both tradition and innovation, reflecting a commitment to sustainable, ethical jewelry practices without compromise.

Ideal for those who appreciate refined craftsmanship and a ring that moves seamlessly from morning light to evening gatherings, its comfort fit and modest height ensure it complements a variety of hand shapes and personal styles.

Should you need a custom adjustment, resizing is handled with care to preserve the integrity of the setting and stone.
