Hello, I've emailed one of you who responded to me personally to a previous question, but haven't gotten a response. Perhaps you'd rather respond through the forum so more people can be educated so as not repeat my stupid blunders on eBay. God knows, it'd make my husband happy. Currently, there's a pendant I'm lusting after in the $10 - $50 range called a Mexican Matrix Yellow Opal. It's in that crappy 925 silver, but I don't care. I'm trying to find one to bid on that isn't a solid color, but has "chunks" of yellow in its composition. Meanwhile, back at the ranch, I'm wondering what the heck the darned thing really is? I keep thinking about those bugs I'd make when I was a kid with the plastic goo in the metal shapes in the heating element. Is it like that kind of fake? Or, is it a real stone with the misnomer of "opal?" Thanks!
