I googled around for photography tips and found this link talking about inexpensive ways of capturing jewelry.
Seems the use of a flash and direct, glaring lights are the problem.
So, I need to get a deep, frosted white bin. I also like her suggestion of using inexpensive lamps with specialized bulbs.
Not sure how soon I'll get all that stuff. With Thanksgiving tomorrow and Black Friday after, I don't want to go near a store.
Update:
Oh, looky here. Another photo box.
Another update:
I made the box at the second link. Been trying it out with one lamp and a piece of printer paper folded first lengthwise so that it can stand on its own and then widthwise so that it can reflect the light in a couple directions.
Most of what I've read indicates that you shouldn't use a flash. That works for me sometimes. Other times it comes out blurred. That might be corrected with a tripod.
Also noticed that the camera doesn't deal well with multiple stones in the pic.
So, here is my favorite of group two in my photo box --


I think I can reduce flash glare by standing way back while zoomed in.
