If there’s one thing I can say about researching antique & ancient jewelry, it’s that you end up with a lot of books on the shelf, and a lot of bookmarks in the browser. Here are some of my favorites!
Antique Jewelry University
Incredible reference for jewelry of all ages older than modern.
Gemological Institute of America
Where I am getting my gemological edumication.
An always-growing resource for gemstones and gemology.
Active message boards about gemology and some jewelry. Very helpful people here!
My favorite (antique) jewelry store EVER.
The Ganoksin Project
Amazing resource and community for jewelry makers.
