This is a beautiful vintage orchid pin or brooch, probably dating to the 1950s or earlier. It is signed, but the name is not discernible. It feature frosted rhinestone leaves, and 3 marquis rhinestones for stamens. The stem is enameled and covered with glass granules fired on. It is also marked 1106.
The brooch has no damage, but it looks like some of the granular glass on the stem has been lost. Overall, however, this is a beautiful and well made vintage pin that you will appreciate.
