Lab-Grown Diamond Engagement Ring
Sunlight catches the gentle curve of a 7 mm round diamond, ready to ignite a quiet sparkle on your hand. This semi-set platinum band offers a refined canvas for your chosen center stone, framed by delicate accent settings that catch light with subtle brilliance.
Crafted in our Williamsburg studio, the band’s cool platinum surface is polished to a satin finish that balances durability with understated elegance. The low-profile mounting ensures comfort for everyday wear, while the artisan detailing around the accents reveals the hand-finished care behind each curve and prong.
Our commitment to ethical jewelry shines through the use of lab-grown diamonds, combining clarity and sustainability without compromise. This ring’s design suits those who appreciate a classic round shape’s lively fire, paired with a setting that feels secure yet unobtrusive.
Its slim profile and modest height make it ideal for stacking alongside wedding bands or wearing solo with ease, fitting gracefully on a variety of finger sizes and shapes. Should you need adjustments, resizing is handled delicately in-house to maintain the integrity of the artisan finish.
