For necklaces and earrings i usually change a lot between diamonds and pearls. And between real jewellery and costume jeweller (i.e. Chanel). But most of the time i go with:
- engagement ring, platinum with 5 diamonds
- wedding ring, platinum with 4 diamonds and 1 ruby
- earring studs (usually pearl or diamonds)
- necklace (usually pearls or an M pendant with diamonds)
- my watch (usually a Raymond Weil or a Seiko Coutura)
- belly button stud (platinum with one red ruby surrounded by 4 tiny pearls)
Sometimes i wear bracelets and they're usually Hermes Clic Clac or Clic H. Or a few sterling silver ones i have.
