Photographing Aurae

Jeez Louise. Aurae is so hard to photograph it's frustrating. I've tried studio lighting, natural indoor lighting and direct sunlight. Sunlight is too harsh. Studio lighting shows the colors the best but you can't see the luster at all. Natural lighting shows the luster but the colors are muted. Wally suggested I try using a black background instead of the gradient background so I tried that last night with my studio lighting. It's actually MUCH better (he's right once in a great while) and the luster even shows up a little too. Anyway, these are my Punk Rock Diva nuggets on eBay right now. There's also a set of chunky discs that match, Rivers of Gold.
