The items shown in the following advertisement pages from 1940 and 1941 N. Shure catalogs, are made up of 22kt gold over white metal filigree. The various perfume bottles and the trays I have had in the past. Some of the filigree has glass jewels. I am pretty sure these were made in the USA to imitate the more expensive items that were made in Czechoslovakia and Austria, but were unable to be imported due to WWII. From experience, I know that the metal is very soft and easy to break, I believe it is lead.
