Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated facets of a 10 x 8 mm emerald-cut diamond, casting a glassy shimmer that stretches across the hand with architectural grace. This platinum engagement ring is meticulously crafted with a low-profile setting that hugs the finger, designed for daily wear without catching or discomfort.

The band’s smooth finish and subtle accent stones frame the center diamond with quiet precision, balancing sparkle and structure. Each ring is hand-finished in our Williamsburg studio, where expert jewelers inspect every detail to ensure lasting comfort and resilience.

Choosing a lab-grown emerald diamond means embracing clarity and sustainability, reflecting a commitment to ethical jewelry without compromise. The cool platinum band complements the stone’s elongated shape, making it an ideal fit for those who appreciate refined geometry and a sleek silhouette.

Its comfort fit and low profile make this ring glove-friendly and stackable, perfect for layering with wedding bands or everyday pieces. Should you need adjustments, resizing is handled expertly in-studio to maintain the ring’s integrity.
