Botryoidal Chalcedony Nugget!

Chalcedony, a microcrystalline variety of quartz. It forms in concentric layers within cavities of rocks, typically igneous rocks such as volcanic basalt. Botryoidal agate forms when layers of silica-rich fluids deposit successive layers of chalcedony around a central nucleus, creating these distinctive rounded shapes.

One of the most intriguing aspects of botryoidal agate is its diverse range of colors and patterns. These patterns are often accentuated by the unique banding and translucency inherent to agate. From vibrant hues of blue, green, and purple to earthy tones of brown and gray, each specimen showcases its own distinct beauty.
