Silver Enamel And retailer Amethyst Chinese Export Brooch

This is a very pretty brooch, made sometime mid last century in China for export. It has a lovely amethyst stone and is surrounded by filigree enameled flowers and leaves in various shades of blue.
There is damage to the enamel fliers on either end of the brooch- please see photos. I have taken this into consideration when pricing.
The back is composed of filigree wire work and is retailer marked “silver” and “ made in China”.
Measures approximately 1 1/2 inches across x 1 inch.
Please study photos carefully as all sales are final.
