Agate: A Tapestry of Colors and Patterns

These layers, composed of alternating bands of different colors and transparency, create mesmerizing patterns that resemble landscapes, clouds, or abstract art. Agate’s color palette spans the entire spectrum, ranging from classic shades of blue, green, and red to more exotic hues like pink, purple, and black.

Onyx, a variety of chalcedony, distinguishes itself with its striking black color and distinct banding patterns. Unlike agate, onyx typically exhibits parallel bands of contrasting colors, often black and white, creating a captivating striped or layered appearance. The term “onyx” is derived from the Greek word “onux,” meaning “claw” or “fingernail,” alluding to the gemstone’s resemblance to the coloration of a human fingernail.
