Lab-Grown Diamond Engagement Ring
Sunlight catches the subtle sparkle of an 8.8 mm round diamond, poised to become the heart of your custom engagement ring. This semi-set platinum band offers a sleek, low-profile foundation designed for everyday grace and resilience.
Crafted in Williamsburg, the band’s polished platinum surface is smooth against the skin, engineered for comfort and durability. Its setting style ensures the center stone will sit securely yet unobtrusively, making it glove-friendly and ideal for stacking with other bands.
Each piece reflects a commitment to ethical jewelry, featuring a lab-grown diamond option that balances brilliance with sustainability. The round cut’s classic fire and scintillation complement a wide range of personal styles, from minimalist to statement.
Designed for hands that move through daily life with ease, this semi-set ring invites you to select a center stone that matches your vision. Resizing is straightforward, handled with care in-studio to maintain the integrity of the platinum band.
