Precious stones' beauty depends on their interaction with light. Foiling enhances the light reflected from within a stone. Before brilliant cuts optimized internal reflection, before clear stones were relatively common, skilled jewelers and craftsmen coaxed more light from their stones by covering the stones' backs with highly reflective foils. By carefully coloring foils, jewelers and craftsmen whitened yellower stones and matched colored stones of different shades. Without foiling, jewels were less beautiful, so foiling was legitimate and desirable.

Expect some antique jewelry to be foiled, especially from the Georgian and Victorian era. Victorian garnet jewelry was often foiled (or backed with gold) so that the stones had a fiery glow.
