Agate

Agate is banded chalcedony, built up as silica-rich fluids deposit layer upon layer inside rock cavities. That slow layering creates its signature bands — rings and ripples in soft greys, creams, warm browns, blues and honey tones that only show fully once a stone is cut and polished. Because no two agates ever form the same pattern, every piece in this collection is genuinely one-of-a-kind.
