I have seen many fire opals in my time, and, generally, opals are not very hard stones - I doubt they can be sharp enough to scratch anyone. However, the setting is another story. I think it's the setting - not the stones themselves that is the culprit. (Unless the diamonds that are doing the scratching.)

I, too, worried that the ring might contain poison. I was hoping no harm would come to Lizzy when she was scratched.

There's something going on with the rings - though I can't quite put my finger on it (no pun intended). I'm trying to determine whether it is an oddity that Mr. PArrish is wearing a wedding ring (most men didn't wear them during Darcy's time) - or could it be that because he's an American he's chosing to wear the ring? I don't think it was common for American men to wear wedding rings back then, either. Still...there's something going on with those rings. (Hmmmm.)

I still don't like or trust Mr. Parrish. I don't particularly care for Mr. Kendall, either.
