opal

Opal is the birthstone for October. It is broadly divided into two types: "precious opal" which exhibits play-of-color effect, and "common opal" which does not. The impression changes greatly depending on whether there is a play-of-color effect or not, but the atmosphere also changes depending on the way the play-of-color appears and the pattern, and if you own one, you will want to collect many more, making it a collector's item.
