Banded Agate Mining Crystal is one of the most abundant yet unique gemstones in the world. It is found in a wide range of colors, from muted earth tones to vibrant pinks, blues, greens, and everything in between. Its banding lines are caused by variations in the stone's chemistry, which can be affected by the presence of other minerals or elements in its environment.

In its natural state, agate can look quite dull, but its intricate wavy patterns and rich colors can be revealed through polishing. Agate slices make for beautiful jewelry, ornamental pieces, and even home décor.
