I will add that the photography ranges from professional to pretty lousy. Most of our jewelry is sold before it's even made, and we barely have time to take a few shots. Sometimes not even that. Plus I hate photography and these were taken with about 10 different cameras over 40 years. They are just to see some work, not for publication.
