These beautifully painted leaf brooches by tania patterson are made from silver. They are really remarkable, as are the delicate bird specimen brooches pictured below. I personally love scientific display, botanical drawings and drawers full of ancient collections of things in museums (though my heart aches for all the creatures sacrificed in the name of science). For me this work is the best of both worlds: scientific in nature on the one hand, and masterfully crafted and referential to the beauty of nature on the other. And no bird was sacrificed in the process. It doesn't get much better than that.
