My poor tiara

So, I took my tiara out of the box yesterday just to look at it and it's all tarnished. I have it stored in tissue in the box it came in but obviously that didn't help. I saw one post that suggested cleaning it with silver cleaner, but I'm not sure if it's sterling. I got it at Barron's in Tri-County. Are they sterling? Anyone have any ideas on how I can clean it and keep it nice for future friends and family that may like it? I'm just bummed it looks like poop already.

Oh no that stinks!!

I'm not sure what it's made out of - I'd recommend jewelry cleaner over silver polish at least to start. I think it's designed for a wider variety of metals. You could also call Barrons and see what they recommend? Good luck!!
