Lab-Grown Diamond Engagement Ring
Sunlight catches the subtle dance of a 7.4 mm round diamond poised to become the heart of your story. This semi-set platinum band offers a sleek, low-profile foundation designed for everyday grace and resilience.
Crafted in Williamsburg, the band’s polished surface and secure setting ensure the center stone will sit flush against the finger, minimizing snagging and maximizing comfort. The platinum’s cool tone complements the diamond’s brilliance, while the mounting’s precise engineering supports easy pairing with wedding bands or stackable rings.
Each lab-grown diamond reflects a commitment to sustainable luxury, offering clarity and sparkle without compromise. The round shape’s classic fire and scintillation bring a familiar yet fresh radiance to your hand.
Ideal for those who value a refined silhouette and practical elegance, this semi-set ring invites your choice of center stone to complete a personalized design. Its streamlined profile suits a range of hand sizes and lifestyles, slipping effortlessly beneath gloves or daily wear.
Resizing is straightforward, handled with care in-studio to maintain the integrity of the setting and metal.
