Black Banded Agate
The Dusky Guardian of Quiet Strength
About the stone
Black banded agate is a variety of chalcedony, or microcrystalline quartz, displaying dark bands alternating with white, gray, or brown; material with straight, parallel bands is commonly called onyx. Known and carved since antiquity, it has no single recorded discoverer, and ancient artisans used its contrasting layers for jewelry, cameos, and protective amulets. Important sources include Brazil, Uruguay, India, Mexico, and the United States, although many commercially sold black stones are dyed to deepen their color. In crystal lore, black banded agate symbolizes protection, grounding, and inner balance
