SYNTHETIC & IMITATION OPAL

Introduction

Many attempts have been made to produce synthetic opal and opal simulants.

These categories are defined here as:

Synthetic Opal

a man-made opal which has the same chemical composition, physical structure and properties of natural opal.

Opal Simulant

a man made material which attempts to duplicate the appearance of opal, but may be made from materials other than silica, and has different physical structures and/or properties to the natural stone.
