The Luminary No. 510™ — 5.10ct Lab-Grown Diamond Platinum Engagement Ring

Crafted Once. Worn for a Lifetime.

Some rings are assembled. This one was made.

This platinum engagement ring was handcrafted from the ground up—designed, modeled, cast, set, and finished with a single intention: to create a piece worthy of a once-in-a-lifetime promise. Crafted in a US ring size 7, it offers a balanced, classic fit that can be resized if needed.

At its center rests a commanding 5.10-carat laboratory-grown round brilliant diamond, chosen not just for size, but for balance, precision, and presence. Graded F color and VS2 clarity, with Excellent cut, polish, and symmetry, the stone delivers exceptional brilliance—bright, clean, and alive with fire from every angle. Free of fluorescence and created through advanced CVD technology, it reflects modern ethics without compromising traditional luxury.

The diamond is elevated by a hand-cast platinum setting, chosen for its strength, density, and enduring beauty. Platinum does not wear away—it develops character over time, making it the metal of choice for heirlooms meant to last generations. Each contour of the ring was refined by hand, ensuring both comfort and structural integrity worthy of daily wear.

Encircling the centerpiece are twelve precision-set accent diamonds—subtle brilliance that enhances light without distraction. Their role is quiet reinforcement: symmetry, harmony, and glow—so the center stone speaks boldly while never standing alone.
