Lab-Grown Diamond Engagement Ring

When light catches the gentle curves of this heart-shaped diamond, it sparks a quiet conversation between brilliance and sentiment. Nestled within a delicate halo of platinum, the 5 x 5 mm center stone radiates a soft glow that feels both intimate and enduring.

Crafted in platinum for its cool luster and resilience, the ring’s halo setting enhances the diamond’s silhouette while maintaining a low profile that rests comfortably against the skin. Each facet is meticulously polished and inspected in our Williamsburg studio, ensuring a finish that balances sparkle with everyday wearability.

Our commitment to ethical jewelry is reflected in the lab-grown diamond’s clarity and origin—cultivated with minimal environmental impact and maximum care.

This design suits those who appreciate romantic symbolism paired with modern craftsmanship. Its subtle halo complements slender fingers and layers beautifully with other bands, while the comfort fit ensures it can be worn daily without distraction.

Should you need a custom adjustment, resizing is handled expertly in-house to preserve the ring’s integrity and balance.

We invite you to explore this heart-shaped halo ring in person at our Williamsburg studio or begin your custom design journey online, where thoughtful craftsmanship meets personal expression.
