Vintage 1980s Signed Two-Tone Swirl M Jent Leaf Wing Wave Mixed Metal Brooch Pin

Hello, you're looking at a vintage 1980's signed M. Jent two-tone modern swirl brooch/pin. It has a versatile shape, resembling a leaf, wing, or wave horizontally, and it could be a teardrop vertically. It measures about 2 3/4 inches long and 1 1/8 inches wide. I am unsure of the metal used, but the maker is M Jent. It closes with a rollover safety clasp which is working. Condition-wise, there is a general patina/tarnish to it, and there is some wear near the tip and other areas of the pin. There is also some general wear along the edges.
