agate

Agate is a type of mineral that forms when silica-rich solutions deposit layers of microcrystals within rock cavities. These layered deposits create colorful, banded patterns that are often polished for decorative use. Found mostly in volcanic rocks, agate's unique bands and vibrant hues result from mineral impurities and variations during formation. Valued for its beauty and durability, it is commonly used in jewelry, ornaments, and collector pieces. Its intricate patterns and natural color variations make it a sought-after gemstone and decorative material, embodying both geological history and aesthetic appeal.
