Dune
A fancy yellow princess-cut lab diamond on a freeform contour, with ten pavé accents arranged in a halo arc along the shank. The contour follows no rule except the stone's — a soft irregular line that holds the diamond the way a ridge holds light. Named for the shape the wind makes.

Care
Solid gold is durable enough for daily wear, including water exposure. For longevity, we recommend removing the ring during high-impact activity (weight training, rock climbing, manual labor) and avoiding direct contact with harsh chemicals including chlorine, bleach, and acidic cleaners. A soft-bristled brush and mild soap in warm water is sufficient for home cleaning. Complimentary cleaning, polishing, and inspection within the first year of purchase — see our Warranty & Repairs page for full coverage details.
