Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender beam that dances across the skin. This semi-set solitaire ring invites you to select a center stone that measures 9 by 4.5 millimeters, its tapered points lending a graceful drama to the hand.

Crafted in 18K white gold, the mounting features a delicate yet secure setting designed to cradle the marquise with precision. The band’s smooth finish and modest profile ensure comfort for daily wear, while the artisan’s hand-polished surface reflects a quiet Brooklyn studio ethos.

Each diamond chosen for this ring is lab-grown, offering a clarity and brilliance that honors both sustainability and ethical sourcing without compromise.

The slender silhouette suits those who appreciate a refined statement piece that elongates the finger, pairing effortlessly with stackable bands or worn solo. Its low-profile design slips easily beneath gloves and daily activities, marrying elegance with practicality.

Should you need adjustments, resizing is available to ensure a perfect fit, crafted with care in our Williamsburg workshop.
