Jugendstil is the German and Austrian counterpart to the more international Art Nouveau movement. For that reason, the designs have similar characteristics as the art nouveau style - with some key differences. Most notably, Jugendstil tends to be more abstract than purely naturalistic.
It included jewelry but also included all other art forms, like the visual arts and architecture. On Glass Made to Emulate Gemstones. Glass has long been used by jewelers to simulate natural gemstones. For instance, during the Georgian era, black dot paste is a term that refers to a style of glass that was made to simulate the sparkle of natural diamonds.
But in the 1940s, the use of glass to simulate gemstones ramped up more than ever before. World War II constrained both fine materials and pocketbooks, so more and more designers (including high-end designers) focused on glass to re-create the distinctive properties of different gems. High-end designers thus began making costume glass jewelry - but with the same attention to detail, high craftsmanship, and design skill that was applied to fine jewelry. _gsrx_vers_1516 GS 9.3 (1516).
