This brooch, currently in the collection of the Jewellery Museum at Pforzheim, incorporates diamonds, enamel, rubies, amethysts, and a topaz. It is centered around a truly amazing set of baroque pearls (and notice that the "head" pearl actually has an "eye" - a tiny round pearl embedded in the matrix.) Shows influences of both Art Nouveau and Renaissance design. Image Courtesy of Art Nouveau Jewelry by Vivienne Becker, 1985.Looks to me more like the Flying Spaghetti Monster.
