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.
