Opinions needed!

I've finally started to photograph my current jewelry inventory to put up on Etsy, and I'm running into trouble with my NEW line of acrylic, laser cut jewelry. I can't decide what background to use... what do you think? This gray pattern is what I use on my other (metal) jewelry, but I'm not sure it 'goes' with the new stuff. Also, since I have a bunch of colors in the new line (red, pink, orange, yellow, blue, green, purple, black, white........) if I go with a contrasting background, every picture would be different!

What do YOU think?!
