1930s Art Deco Reverse Carved Round Pagoda Rock Crystal Pendant 18" Necklace

1930s Art Deco Reverse Carved Round Pagoda Rock Crystal Pendant Chain 18" Necklace. Round Pagoda intaglio. It looks to me as though this is the original chain as well but I can't be 100% certain about that. This pendant necklace is in great vintage/antique condition with minimal signs of age and use.
