👉 Iridite is a mineral that is composed of two different elements, iron and zirconium. It is commonly found in rocks such as granite and marble. The name "iridite" comes from the Greek word "iris," which means "eye," referring to its resemblance to the eye-shaped structure of the sunstone. Iridite has a beautiful iridescent appearance due to the way it combines iron with zirconium, creating a unique shade of blue-green coloration.
