This is a very unique Repoussé 9.5” Trumpet Vase.   The type of metal is unknown (a strong magnet does not stick to it).  I don't believe this to be sterling silver, but possibly silver plated.  I am no expert so please review the pictures carefully to come to your own conclusion regarding the metal and plating. The interior is hand blown glass which has caused the glass to "bulge" out of the openings in the vase.  The glass is rather thick and very clear.  The metal work is very detailed; I've included close up photos of each side (top and bottom) to try to shows the extent of the metal work.  Thanks for looking and please let me know if you have any questions!
