Lab-Grown Diamond Engagement Ring

Under the soft glow of a Williamsburg evening, the halo of delicate platinum prongs cradles a luminous round lab-grown diamond, its 4.8 mm diameter capturing light like a quiet pulse. This engagement ring balances refined craftsmanship with everyday grace, featuring a low-profile halo setting that gently embraces the finger without catching.

Each ring is meticulously hand-finished in our Brooklyn studio, where the platinum band is polished to a satin sheen that feels cool and smooth against the skin. The halo setting enhances the diamond’s natural brilliance, creating a subtle frame that amplifies sparkle while maintaining a comfortable fit for daily wear.

Crafted from ethically sourced lab-grown diamonds, this ring reflects a commitment to sustainability without compromising on clarity or fire. The choice of platinum ensures durability and hypoallergenic wear, ideal for those who seek both elegance and resilience.

Designed for the wearer who appreciates understated romance, the ring’s slender band and low-profile halo make it an excellent companion for stacking or pairing with a wedding band. Its balanced proportions suit a variety of hand shapes, offering a graceful elongation without overwhelming.

Should you need a custom fit, resizing is available to ensure the ring sits perfectly. Each piece is carefully inspected before leaving the studio, with typical lead times reflecting our dedication to artisanal detail.
