Last year, I ordered a few dozen bedazzled reading glasses made in China from eBay to give as party favors…the price was ridiculously low, and I wondered about the quality. I was shocked at how well-made and cute they were – far nicer than the price would indicate. I’d have no problem ordering a $25 necklace from eBay and taking my chances.
What about this one or this?
I wonder if all rhinestone is too boring…but this is a fashion statement.
I don’t think swan works as well as peacock for the zoo theme though I’m probably off base. I think this is being overthought. The first necklace was perfectly fine and unique for the occasion 
But Pizzagirl… It is soooo much fun to look at shiny, pretty objects! 
Well I saw the bird without looking at the caption, but I am good at those sort of games. Anyway, I think it would be fun, and the price won’t break the bank.
I vote for your original choice. I prefer the simpler monochromatic design. Just my preference–it’s obviously pretty subjective. B-)
