Aurora Borealis & Gammatic Stones Mid-Century-Modern Brooch and Earrings Set. Unsigned Hobé.

This beautiful set features the rare “gammatic” stones, a peculiar shape for rhinestones seen first in the late 1950s. They were produced in Austria by Swarovski and largely employed in high-end fashion jewelry, such as by Dior and other French couturiers. This specific design has been attributed to Hobé, and verified to a signed exemplar.
