OPAL

Description

Opal is a hydrated, amorphous form of silica, known for its “play of color,” a phenomenon where it displays shifting hues due to the way light interacts with its structure. It’s a mineraloid, not a true mineral, due to its amorphous structure and can contain varying amounts of water, usually between 6% and 10%. Opals are found in various colors, including black, white, fire, and other shades, and are valued for their beauty and unique characteristics.
