What happens if something that's not metal goes in Liver of Sulphur?

Odd question... I've read the other threads on oxidizing silver and using LoS in general, but I haven't found any reference to this.
I'm wondering what would happen if I put a finished product into a LoS mixture rather than doing the pieces of silver beforehand?
For example, a necklace that has all silver components EXCEPT the centerpiece is a chunk of agate.
Does Liver of Sulpher hurt things like gemstones, glass beads, etc? Or is it safe to dump an entire piece in there to oxidize and just rinse it after the fact?
Any advice from a 'pro' would be much appreciated :)

"Most stones will withstand the oxidation process — be cautious with polymer clay and porous stones, such as opals and pearls. Test first if you are not sure how it will affect your stones. If you are making jewelry with pieces that you do not want oxidized, or with components that will not hold up well to the process, oxidize prior to assembly. "

Like LittleLoveable said about opals and pearls...be careful. With other stones however, I always set my stones before I do any type of patina. LoS is a natural plant fertilizer so it's not like some strange acid chemical that is going to eat the stones. I've even put it on labradorite, moonstone and sunstone with no problem.

I put sardonyx and black onyx in, and they were fine. They are also hard and black........ I wouldn't do anything below a mosh hardness of 6- no turquoise, opal, pearl, etc...
Oxidation does hold up well to being worked. I oxidized all of the metal on a pair of earrings, prior to assembly. None of the oxidation came off.

I believe that you can also "paint" LOS directly onto an item rather than dip it, so maybe you can try just applying it where you need it and avoiding the stone. Of course the stone would still be exposed to it a little when you dipped the piece in the cold water, but not nearly as much as dunking the whole thing in a hot LOS bath!

Is there a place to find many stones and their place on the Mohs' Scale of Hardness? I'm trying to find what I can and cannot oxidize without having to cut all the metal pieces, oxidize that and then put the oxidized pieces together with the stones. I'm not finding a lot of help. I feel lost.
