Jewelry sellers: what's the most painful part of product photography for you?

Genuine question for everyone selling jewelry (or any hard-to-shoot product) on Etsy, Shopify or Amazon. What eats most of your time or budget: retouching? Getting on-model shots? Video? Keeping a whole catalog consistent? We're launching NeuroViz here tomorrow and your answers directly shape what we build next. I'll reply to every comment.
