This may be totally irrelevant to many of you, but it was a big help to me so I thought I'd share. I bought my BMs' sterling silver & smoky quartz jewelry a really long time ago (ok, before I was even engaged!) and it has gotten really tarnished (I should have kept it in plastic zip lock bags). I was worried about using a silver cleaner becuase of the quartz stones, but found the coolest method online that works. Place the jewlery in an aluminum pan (like a disposable pie pan from the grocery store), cover all the silver with baking soda, and then pour boiling water on. Some chemical reaction occurs which gets the silver sparkly clean (and didn't damage the stones). Was a big help to me, thought I'd pass it along!
