“Kyoto Opal” is a term used to refer to the synthetic opal material developed by Kyocera in Kyoto, Japan. Appearing identical to naturally occurring opal, Kyoto Opal is manufactured to overcome the gem’s inherent brittleness, which gives it a tendency to split and crack. This enables the material to be cut into more diverse shapes. It can be used in various applications to provide rich and subtle hues and tints through special coloring techniques.
