Thanks Susie. I was thinking... "How could you get a solid black background and still light the subject?" but I guess I would just have to somehow suspend the ring so the background was not catching any light, as opposed to setting the ring on a table or something like I've done here.
Thanks for your thoughts, I'll have to try again on my own. I think I need to spend some time analyzing some actual ring ads.

Travis-
When you are photographing highly reflective and polished products you are NOR really photographing the object (per se) you are photographing the reflection of the light source. The reason your image of the ring looks black and the diamond has black spots is because you have "DARK FIELD LIGHTING" where you need "LIGHT FIELD LIGHTING" You establish the light field by using a large soft box close and over the product- slightly from the back of the item and fill in with white reflector cards made of bits of white seamless paper or white Foam-Cor(tm. Start off with a white seamless background of white background paper. If the entire item turns white and blends too much, you can hang some strategically placed black ribbon to create outlines here and there. You are basically working in a tent but it is easy with small pieces of jewelry, Use seamless paper for a "sweep" background and use more of the paper for the "walls"- the fill card will take care of the rest.
Don't lay the ring on it's side. Prop it up with a tiny piece of that stick on stuff- the used to call it NUTTY-PUTTY- you can now find it in hardware stores- it is used to hang light weight pictures on walls without nails- it may be caked STICK-UM, I forgot the brand name. You need to feature the stone. Black spots in diamonds indicate diamonds of lesser value- so you don't want to blacken the stone with bad lighting. Jewelers describe good diamonds as having "fire"- you need brilliant reflections in the stone but no blow-outs because you need to show the facets- that shows off the "cut".
If you want a black back background you can place the ring on a sheet of clean window glass and light it as I have described- still using light field lighting. Keep the glass a about 16 inches from a piece of black velvet and use small white fill cards to light up parts of the ring that look black- a little black to give it shape is OK. You my need a polarizer to kill reflections in the glass- this depends on the exact angle of incidence.
Good luck!
Try a shot and post it for me. I hope this helps. Ed
