This is a great question! I always wonder what everyone's staples are, jewelry-wise.
I wear a gold/diamond pendant and gold/diamond hoops constantly. I don't take them off to sleep or shower. Before I leave the house, I slip on my engagement/wedding rings (they are soldered into one) and maybe a right hand ring. That's pretty much it! I would like to add more or mix things up a bit, but I'm just so lazy and usually in a rush to get ready in the morning.
That's my problem...too lazy to rotate. Other then the Roadster and a neat diamond horseshoe necklace I haven't bought much jewelry recently.I'm making an effort to rotate. No current jewelry staples other than my gold wedding ring. I do, however, wear at least one pearl every day.
