I don't wear jewellery to bed - I take it off and put it straight in my jewellery box. I'm getting a little ivory trinket box with my initials from my DF for our wedding that we will store our wedding rings in on my bedside table.
i wear my wedding and e-ring, diamond earrings and diamond chain necklace 24/7. Larger pieces that I add to wear during the day come off when i get home.
I never take my diamond studs out. I have only recently started to remove my wedding rings and watch as I am developing arthritis in my ring finger. I hate removing my wedding rings, I guess I am too sentimental.
My wedding band is all Chanel set, so I remove all jewelry...except some nights I am too lazy to remove my diamond studs since they have the screw back. They are set in platinum (2cttw) and my jeweler frowns at me when I tell him I sleep in them! Platinum is so soft, he states that I could strip the backs.
I used to sleep with my engagement and wedding rings on as I wore them 24/7 - now though I remove all jewelry before sleeping. I realized it was more comfy for me that way.
