What's the difference between a diadem and a tiara?
1 Answer

The main difference between a tiara and a diadem is the specificity of the shape. A tiara is a semicircular headpiece that typically arches upward toward the middle, while a diadem is a semicircular headpiece of any shape. All tiaras are diadems, but not all diadems can be classified as tiaras. Shop a collection of tiaras from some of the world’s top sellers on 1stDibs.
