Agate is a kind of microcrystalline quartz that is often tumbled and used in jewellery and other decorative things. It is classified as a semiprecious gemstone. It is naturally attractive and comes in a wide range of hues, making it appealing to a wide range of collectors and gemstone lovers.
Agate comes in various hues, including brown, white, red, grey, pink, black, and yellow. Impurities cause the hues, which appear as alternating bands inside the agate. The various hues were created as groundwaters of various compositions seeped into the hole. The banding within a cavity provides a record of changes in water chemistry.
For thousands of years, agates have been utilized as jewels. They were among the first stones fashioned by humans. They are now carved into cabochons, beads, tiny sculptures, etc. Agate cabochons are popular in jewellery and may be found in rings, earrings, pendants, and other items.
