Ever wandered why the tutorial section on colored stones is so short

If you ever want more, here's an entire course on it ! (LINK) by Prof. Jill Banfield at UC Berkeley.

No telling what one can find on the Net these days

Yep Ana there are wonderful things now on internet!
The best information source on gemstones I get to know is the following website that present an incredible number of spectrum and inclusion photographs... (They even have a search engine on that...) They have also several very good articles.
Have a visit:

geminterest.com

My favorite gemology website for sure...
All the best,
