The classic halo setting that is so well known today originated in the Deco art era of the 1920’s. This era placed emphasis on symmetry and the use of geometry and geometric patterns. The beautiful symmetrical circle that surrounds the centre stone of the ring was a perfect fit for this symmetrical minded era. Even Though the halo setting has not completely died out of popularity, it is safe to say that it is considerably much less popular than when it was first introduced to the world of jewelry.
Much like any fashion trend, different styles of engagement rings gain and lose popularity as resources are more abundant or scarce. During the Great Depression the Halo fell out of fashion. The halo made a comeback during the Hollywood Glamour period but lost popularity quickly because of the scarcity of resources during WWII. The halo style made another appearance in the 1960s but soon disappeared. More recently it has made a stand once more. Much like a circle has no end, the beauty of a halo ring may fall out of fashion but will never truly die.
