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.
