Hey y'all,

I made these sterling silver stud earrings last night, and only noticed this rust-like color in the morning light when i went to take the photo.
What's going on??? I used Midas gel LOS (like i have plenty of times), tumbled, buffed and polished. Everything was the same process as usual but I've never seen this appear before... any idea what happened, if i can fix it, and how to avoid it from happening in the future? THANKS!
