Here’s a cool and nifty looking artisan signed brooch of colorful iridized metal with modernist design, circa 1990s. 

The artisan made pin consists of folded cutout metal with a scalene triangular shape, decorative fold, and rainbow iridized surface with geometric designwork in shade, of blue, purple, pink, green and honey.

It also has two decorative square metal studs, brushed patterned underside, and engraved artist’s signature that has remained undecipherable (see last pic).

The brooch measures 3&1/2 inches in length at its longest point by 1&7/8 inches across the top, and weighs 9.2 grams.
