Agate

Agate is a patterned variety of chalcedony whose bands, translucent edges, clouds and mineral inclusions create an extraordinary range of appearances. Some pieces are subtle and earthy, while others carry vivid color and dramatic patterning.
For centuries, agate has been used in seals, beads, carvings and protective ornaments. Contemporary gemstone traditions connect it with stability, balance and the ability to remain composed under pressure.
Agate is frequently dyed or heat treated to enhance color, and those treatments are not always visible from photographs. Check individual product descriptions where natural color matters. Rather than expecting every bead to match perfectly, choose agate for the irregular pattern and visual variety that make each piece individual.
