I have a decantor 8" high. amberinia glass and it looks like there was an acid wash that makes the exterior look textured like ice. There are also medallions on the exterior surface that are sun rays, look to be made by gold. The medallion do not have the acid etch buth have a sun ray motif. There is a top that is covered by sterling and also there is a colar of silver. It appears to be 19th century. Is this Loetz? or can you assist me? for photos please email.
