Opal can be tricky to grade and value, so many characteristics, all interacting with each other. Here is a simple and accurate solution.

Opal Smart Chart is opal appraisal software capable of generating an accurate, up-to-date monetary value for any variety of Australian Opal. Smart Chart has been developed by Peter Evans, current President of the Opal Association with over 40 years opal trading experience.

The program asks a series of fully illustrated questions relating to the characteristics of the opal being appraised, a simple click of the mouse on the relevant photograph in each question is all that is required to generate the value of your opal. Hundreds of detailed and enlargeable photographs aid your grading routine.
