This pretty pin or brooch dates from the late Victorian era, circa 1890. It is made of a yellow colored metal, likely brass, and has a central plaque of inlaid stones, know as pietra dura - Italian for inlaid stones.
The pin is oblong in shape and the metal forms a delicate frame around the plaque. The plaque has a black background, likely onyx, and the flowers at its center are white blue and orange, with green leaves. It is most likely Italian in origin, as these were popular tourist for Americans doing the Grand Tour. The stones are examples of those found in the area - likely lapis, carnelian, etc.
The pin has a typical c-clasp closure, common during this time period. It has a length of 2" and is 1/2" wide. It is in good antique condition with only some minimal scratching to the onyx, only visible with a loop.
