Hello everyone! I just bought my first vca piece a couple of days ago, an onyx vintage albambra pendant necklace. After watching a youtube video about the “shake test” I realized my pendant does make a small rattling noise when I shake it. I also noticed these air lines/gaps only when I hold it up to the light (not visible when worn or just looking at it without holding against the light). I also saw a thread here where it seems like this is more the norm these days (some people went in to exchange and found that all new pieces have gaps). Can someone talk me down from my panic 😅 Is my stone going to fall out over time because it’s loose? Should I just stop worrying about it and wear it? Thank you so much!!
