OK - you know I have a vested (personal) interest in this topic, but I am just searching for a link for the history site where we had chronological eras and came across some gemmology links.
I thought perhaps people may be interested - especially the kids that are attending some gemmology workshops
So I thought I would start a thread where I can add links and info' as I come across them if it is of interest.
(Please Note - these links are not affiliated with Renascent in any way - we are simply offering them to you for additional information - please let us know if there are any that are deleted or inappropriate - please also feel free to send us some we may not know about)
