Art Nouveau Sterling Silver & Hematite Bow Festoon Necklace

Beautiful sterling silver and faceted hematite gemstone necklace.  Three oval faceted hematite gemstones prong set in a sterling silver setting with a bow design above each dangling stone.  This festoon style art nouveau necklace straggles the deco and nouveau design styles with a stark geometric modern deco setting but bows indicative of art nouveau.  Designer hallmark is on the clasp which looks to me like it says “AMOO”.  See in photo.  Started in 1919
