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.

- A note on 10k: 10-karat gold is the strongest everyday gold alloy — more scratch- and dent-resistant than 14k or 18k, with a warmer, quieter tone. We chose it deliberately, for jewelry that's meant to be worn, not stored.

Care
10-karat 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. We offer complimentary lifetime polishing and inspection on every piece.
