Gemstone Guide

1. Colour

   Hue, tone and saturation: see the actual colour, rather than the name alone.

2. Origin

   Origin provides context and should be considered separately from the quality of an individual stone.

3. Treatment

   Understand what heating or enhancement has changed.

4. Gemstone Report

   Learn what a laboratory report can, and cannot, tell you.
