Agate is a very common stone that is often used in jewelry.
It is found in a wide range of colors,
including black, gray, brown,
reddish, green, pink, blue, and yellow.
Agate can be flecked with color and is often banded,
exhibiting layers of quartz.
Agate is porous and takes dye easily;
it is frequently dyed to enhance the coloration and the banding.
White agate was used often in Victorian jewelry,
mostly as a background.
Moss agate has green,
red or black dendritic inclusions.
Onyx is agate whose bands are parallel.
Eye agate has banding arranged in concentric circles.
