I like this type of photograph best. It's simple, bright, and colourful. I think the stand is kind of distracting for your listing photo.

Check out how other shops photograph their earrings as well, and look up which pages your earrings show up on to see how they appear next to other listing photos.
I totally loved making things with these plastic beads when I was kid! Possible listing title and tag words - geekery, geek jewelry, dangle earring, multicolor earrings, sterling silver, handmade jewelry, funky earrings, etc.
Hope this helps!
