Andesine is a type of feldspar silicate mineral that was first discovered in 1841 in Colombia. In the early 2000s a few red exemplars appeared on the market, although it was later discovered that they were artificially colored. The lack of proper authentication is one of the challenges when estimating andesine's value.
Andesine is relatively brittle and can crack, but can be used in jewelry. Red andesine stones are usually used as a substitute for ruby or spinel, which look similar, but are much more expensive, compared to andesine's price.
Andesine's value chart will help you evaluate the worth of the gemstone you own, based on its colour, cut, carat weight, and clarity. It varies from transparent to translucent and from red, orange, and honey yellow, to green.
Natural deposits of andesine exist in the Andes mountains in South America (which it is named after), as well as in France, Germany, Italy, among other locations.
