In this TOC (Table Of Contents) you will find pages that have been published presented in blue and pages that yet need to be written presented in red. For better navigation, we list the pages in 3 categories:

  1. Theory - Basic and in-depth mechanisms involved in gemology
  2. Practical - Descriptions of instruments, techniques and other practical discussions
  3. Gemstones - Information about the gemstone at hand

For the neophyte it is best to start in that order as some words and principles introduced in the theory pages will need to be understood first. At the very least, one should learn the theory in the "basic" sections of the pages.
Although gemology is not rocket science, some science and math is involved. We don't believe in the dumbing-down of gemology, so you should be ready and willing to expand your horizons. If you find any of the technical concepts difficult to visualize or grasp, go to the forum (the link is above) and ask. We will help you with it, and at the same time you will help this project become more complete for those who come after you.

We never said it was going to be easy. But it's a heck of an interesting ride.
