I have two Roman Glass rings. One is from Or Paz and the other is from another shopping channel. I've had both pieces for about 2 years and they still look as beautiful as the day I received them.
I'm very careful while wearing my jewelry. I don't clean the house while wearing it, wear it to the beach or pool etc. I apply hand cream and then put my rings on.
I always remove my jewelry before washing my hands; that goes for gold, silver, gemstones, diamonds......the whole shebang. Honestly, I never heard about not getting Roman Glass jewelry wet - that's good to know even if I never wash my hands while wearing jewelry. And I never heard about not handling it too much - also good to know, even though I've handled both rings a lot.
As I said, I've owned my rings for 2 years and so far, so good. The color still looks the same and I've never had any flaking.
