Trombone safety clasps were used from the 1890's to the 1920's which is how this brooch was
determined to be an antique. I am not an expert but if I was to make a guess, I would think that
the style of this brooch is of the Victorian era.

The pin and trombone clasp work great.  All the stones are intact. The only condition issue I see is
if you look very close up, you can see some wear on the metal. where a silver tone is showing.

This brooch is approximately 1 inch long.
