What is Fake Opal?
A fake Opal is a manufactured material that imitates natural Opal. It is created using synthetic opal, plastic, or glass and comes in different colors and patterns. Unlike a natural opal, a fake Opal is stable over time and won't crack or turn yellow, which makes it low maintenance. Additionally, it is easier and cheaper to manufacture than a natural Opal.
