Rose Gold Plated Jewelry Set

I got this set as a gift and everything is literally brand new. However, the hoop earrings has started to discoloring due to a weather humidity (I guess). Other items still look OK to me! That’s why I reduced the price even though I haven’t touched any of them. The retail price for this set is $70 (not include taxes and shipping fee). So I think my listed price is not too bad
