Physical properties

Formation & geological history

Silica-rich groundwater deposited chalcedony and quartz in a cavity within volcanic rock; geodes formed over geological time, commonly during the Cenozoic or earlier.

Uses & applications

Used for jewelry, display pieces, and collections; agate is also used for ornaments and small decorative objects.

Geological facts

The small pointed crystals lining a cavity are called druzy. Orange coloration can result from iron oxides or applied dye.

Field identification & locations

Look for banded or waxy chalcedony surrounding a crystal-lined hollow; common sources include Brazil, Uruguay, and Mexico. Check for natural color variation, since dyed pieces may have unusually vivid, concentrated color.
