Lab-Grown Diamond Engagement Ring
Morning light catches the subtle sparkle of a 5.5 mm round diamond, poised to become the heart of your story. This semi-set platinum band awaits your choice of center stone, designed with a low-profile setting that nestles close to the finger for everyday ease.
Crafted in Williamsburg, the band’s polished platinum offers a cool, durable foundation, accented delicately to enhance brilliance without bulk. Its comfort fit ensures the ring moves naturally with your hand, while the secure prong setting balances protection with maximum light play.
Each piece reflects a commitment to sustainability through lab-grown diamonds, marrying clarity with conscience. The round shape’s classic fire and sparkle suit a range of hand sizes, especially flattering on slender fingers or when paired with stackable bands.
Resizing is straightforward, handled carefully in-studio to maintain the integrity of the setting and finish. Whether you visit us in Brooklyn or design online, this semi-set ring offers a thoughtful starting point for a personalized engagement ring.
