Retro DECO order 1940's Style Pin, Sterling Silver, Mother of Pearl and ONYX with Marcasite Brooch, Large and Heavy Statement Piece!

Made in the 80s or early 90s but in a retro 1940's style, this amazing brooch has a terrific Art Deco design using black onyx, mother of pearl and marcasite stones. The genuine stones are large, black onyx cabochons and mother of pearl shell.

This statement piece is fabulous and large! All of the marcasites are intact and the piece is in perfect condition order.

The safety catch in the back works beautifully. There are three hallmarks on the back. One says Sterling, there is a copyright symbol, and another that is probably the maker's hallmark, although I don't know who that is.

It measures just under 3“ wide x 1 1/2“ in height.
A gorgeous brooch in excellent condition!
