How can I tell if Basra pearls are real?

Basra pearls, which originate from the Persian Gulf, are usually much lighter than other varieties of pearls and tend to have irregular shapes. When you feel a genuine Basra pearl, it will be cool at first, then warm up when worn. Authenticate a Basra pearl with the "tooth test," where you rub the pearl against your front teeth. If the texture is slightly rough, then it's a genuine pearl. Shop expertly-vetted Basra pearl jewelry from some of the world's top sellers on 1stDibs.
