Sunlight catches the elongated curves of the 7 x 5 mm oval diamond, casting a subtle glow that gently elongates the hand’s silhouette. This platinum engagement ring is crafted with a low-profile setting that nestles close to the finger, designed for everyday wear without catching or discomfort.

The oval center stone is secured by precise prongs that balance security with light exposure, allowing the diamond’s soft brilliance to shine through. Accented by delicate side stones, the band is polished to a smooth comfort fit, ensuring it slides on effortlessly and rests naturally.

Each ring is meticulously finished in our Williamsburg studio, where expert jewelers inspect every facet and setting to meet exacting standards. The platinum’s cool tone complements the diamond’s clarity, while its durability supports a lifetime of daily moments.

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

This design suits those who appreciate refined craftsmanship paired with practicality—ideal for stacking with wedding bands or worn solo for a subtle statement. Its low profile makes it glove-friendly and unobtrusive for active lifestyles.

Resizing is available to ensure a precise fit, and typical lead times reflect our hands-on approach to custom finishing.
