Colored Gemstones, Pearls & Birthstones
There are many different colored gemstones including pearls and all the birthstones that we use in many of our designs. I have listed below two links to two top organizations, the AGTA and the GIA. These sites have lots of great info on just about any and every colored gemstone commonly used in jewelry today.
For all you gem lovers, I have two top recommendations:
1. The American Gem Trade Association (AGTA) website: http://agta.org/gemstones/index.html
Lots and lots of information on every colored gemstone you are likely to ever see, and then some!
And check out their free Gemstone Information Manual on that page too.
2. The Gemological Institute Of America iPad app: https://itunes.apple.com/us/app/gems-gemology/id515113263?mt=8
The app is called, Gems & Gemology, and has free issues to the GIA world class publication by the same name. Very informative. Lots of fun and in depth information for gem lovers.
Also check out their website at: http://gia.edu.
Lots of good info there on gems and diamonds.
