I would say that despite it not being the popular opinion here, all fine jewelry is not supposed to be worn in the shower etc. This includes solid gold pieces from cartier or tiffany or VCA. The comment is that it will wear. If you go onto the VCA website it states that all their pieces are not to be worn or touch water, it doesn't specifically say MOP vs Onyx etc. is better. I have a MoP necklace that I've personally worn in the shower for a long time, and I take it off to inspect it once in a while. There really is no difference especially when compared to the 5 motif MoP bracelet my mother just purchased for her birthday. If there is damage eventually I will come to terms that the stone itself only costs around $100-$200 to replace from VCA as confirmed with my SA. If that is the cost of it to allow me to enjoy the piece more freely I think it is really reasonable. There is a lot of fear around these pieces, similar to fear on how the love bracelets can scratch or how Chanel lambskin doesn't hold up the way caviar does etc. I would say at the end when you purchase luxury I personally want to enjoy everything I save up for to purchase and not have to worry about babying it all the time, as it wouldn't fit my personal lifestyle.
