This is a Sterling Silver Overlay Perfume Bottle w/ Dark Green Glass. The ball shaped Stopper has (6) Sterling Silver Overlay bands that start at the top from a small circle with an engraved design of crossing lines and the bands come down from that point down around the green stopper and connect to another band that goes around the stopper neck. The bottom of the stopper has the number #572. The stopper measures 1 1/2" in length and about 7/8" across the top. This Very Ornate Perfume Bottle is encrusted with a Heavy encasement of Sterling Overlay. It has beautiful swirling, flowing, curling around Art Nouveau designs with an almost round Medallion Shield that has not been monogrammed. the bottom of the this Bottle has the number #572. We found this Perfume marked on the bottom edge of the Perfume Bottle 925/1000 fine / Alvin sterling Company(Three marks with an "A" in the middle )/ "G" "1". It measures 3 & 1/4" tall and 2" in diameter. the Bottle has a little bit of residue on the lower inside, but is in great condition and has no damage on it. Two American companies, Gorham & Alvin, dominated the scene and created some of the most exquisite examples available using thick overlays of sterling silver. They both used glass blanks from the Steuben glassworks. Another honorable mention is the La Pierre company, though not as highly detailed as Gorham or Alvin, but nonetheless, beautiful bottles. These higher end bottles usually have an area where a monogram could be engraved, often you will find bottles with owners name or initials in fancy flourishing script. We find this adds a lot of charm to the bottles as well as their History as the engraving is a work of art, which has become almost a lost art. As there are numerous bottles that have cracks in the glass, it is suspected that this is a common occurrence with bottles which have thicker overlay.
