Antique Edwardian Old Cut Diamond Silver Pin Brooch with Gold Pin & Back

Description

This is an exquisite small pin, probably from the Edwardian era. Photos don't do it justice. It weighs
6.4 grams, and measures 1 1/4" wide by 1 1/8"long.
The pin features 22 old cut diamonds set in silver with a gold pin back. There are hallmarks on the c clasp and the top back of the pin that are too small to make out. I don't know the purity of the metal. The three drops that dangle from the bottom move.
Please ask questions before bidding, and view all photos as they are part of the description.
