You can tell before turning it over from its design and high bling factor that this is a classic Eisenberg brooch. This pin has super sparkly large and small chaton rhinestones on the outside and one in the center; radiating out from the center (and slightly higher) are alternating rectangular and marquise rhinestones. All rhinestones are prong set with closed backs in silver tone rhodium plating. This will look great on the lapel of your dark sweater or suit jacket.
Measurements: The diameter is approximately 1.75 inches.
Condition: This brooch is in excellent condition - both the rhinestones and metal setting look fantastic to the naked eye with only a couple flecks visible. With a loupe you can see more flecks. The photographs do a nice job of showing the beauty of the brooch, so use the zoom feature to really check it out.
Marks: This pin is signed "EISENBERG" (no copy right symbol) on a cartouche on the back of the brooch. This signature was used from 1945-1955.
