Vintage Rare Eisenberg Enamel Gold Toned Floral Pendant Necklace

Preowned, good condition, possible small wear, sold as is. see pictures, I couldn't find this exact necklace anywhere it seems to be Rare/unique, signed eisenberg, and from the style of it, it seems it would be from the artist collection. I don't know the exact name. selling as is. beautiful necklace!
