Lab-Grown Diamond Engagement Ring

Sunlight catches the gentle curve of an oval lab-grown diamond, its elongated silhouette casting a soft glow across the hand. Nestled within a delicate halo of platinum, this engagement ring balances luminous sparkle with refined craftsmanship.

Handcrafted in our Williamsburg studio, the platinum band is polished to a satin finish that feels cool and smooth against the skin. The low-profile halo setting secures the 6 x 4 mm oval diamond, allowing light to dance freely while maintaining everyday wearability. Each facet is inspected under magnification to ensure clarity and brilliance.

Choosing a lab-grown diamond reflects a commitment to ethical jewelry, reducing environmental impact without compromising on radiance or quality.

This ring suits those who appreciate a romantic yet modern silhouette—its slender band and modest height make it comfortable for stacking or daily wear, while the oval shape subtly elongates the finger.

Resizing is available to ensure a perfect fit, crafted with the same care as the original design.
