Lab-Grown Diamond Engagement Ring

Imagine the gentle curve of a marquise diamond catching morning light, its elongated silhouette casting a subtle, graceful shadow on your hand. This semi-set solitaire ring invites you to choose a 7 x 3.5 mm marquise center stone, known for its tapered points and elegant drama that visually lengthens the finger.

Crafted from warm 10K rose gold, this mounting balances softness with structure, its slender band polished to a smooth finish that feels light and comfortable for daily wear. The low-profile setting ensures the diamond sits close to the finger, making it glove-friendly and ideal for stacking with other bands.

Each piece is meticulously hand-finished in our Williamsburg studio, where precision meets quiet artistry. The rose gold’s gentle blush complements the marquise’s vintage-inspired shape, while the secure prong setting is designed to protect your chosen stone without overwhelming its natural brilliance.

Our commitment to sustainability is reflected in the option for a lab-grown diamond, offering clarity and sparkle with a smaller environmental footprint. This ring suits those who appreciate refined craftsmanship and a romantic silhouette that adapts seamlessly to everyday life.

Should you need resizing or prefer a custom adjustment, our Brooklyn studio offers attentive care to ensure your ring fits perfectly. Typical lead times accommodate thoughtful creation without rush.
