Necklaces
On necklaces, the nazar bead tends to be worn in an understated fashion, with either the beads running down the chain or as an amulet at the end.
Bracelets
Bracelets with many small little nazar beads are also very common, as bracelets are a common fashion accessory in Turkey.
Earrings
Nazar bead earrings tend to be slightly more ostentatious than other forms of jewelry, often as drop earrings. Stud nazar earrings are common as well, though often-times the point is to show off that beautiful blue color of the nazar bead.
Rings
That deep blue on your finger looks prettier than almost any other color you'll find, and obviously nazar bead rings tend to be cheaper than real stones so it's a perfect fit for your souvenir to take back home.
