92.5% pure silver, 7.5% copper. Hallmarked. Tarnishes over time — that's chemistry, reversible in 30s with the included cloth. Cool-toned, sculptural, ages beautifully.

Grown in mussels, hand-selected per pair for luster and symmetry. Each one is unique. Organic material — no chemicals, no ultrasonic, no perfume.

For colored stones (opal, sapphire, topaz) we default to lab-grown. Chemically identical to mined, lower environmental and human cost.
