Agate becomes brighter rather than faded when worn for a long time. The composition of agate is silicon oxide, and the red part is a lot of iron oxide particles, like vermilion spots (the finer the red spots, the brighter the color). So in general (that is, non-high temperature, chemical corrosion, etc. ), natural agate will not change color.

Wear it close to the skin for a long time, so that the moisture on the skin surface can be integrated into agate, and at the same time, the oil produced on the skin surface can block these tiny gaps, so that the moisture is not easy to lose. The longer the time goes by, the more oil will be incorporated and covered, which makes the light and shadow refraction more obvious and the color more vivid (the process of oil integration and covering is commonly known as "patina").

Extended data:

Agate is formed by the gradual precipitation of colloidal solution containing acid in the crust surface. Therefore, it is mostly layered, and the layers overlap with each other to form a corrugated shape, which is as shiny as wax and slightly transparent or opaque. The colors of agate are mainly green, purple, red, white, light blue, brown and black. In addition, some agates have colorful effects, and many colors are intertwined to form some unique and novel patterns.

Because agate is colorful and beautiful, it has been cherished by people since ancient times and has been given many nicknames. For example, the purple one is called "sauce-stained agate", the red and white one is called "silk-wrapped agate", the one with silky grain is called "cypress agate", and the one with cypress pattern is called "cypress agate";

Those with bamboo-like patterns are called "bamboo agate", and those with fine needle-like other substances or strip cracks are called "hairy agate". Among them, there are impurities like undulating ostrich feathers called "feather agate", and there are also five colors called "brocade rhinoceros agate".
