This brooch is a stunning medium sized vintage blue and black enamel butterfly or moth. The brooch is sterling silver with a gold wash and intricate enamel coloring. The enamel is in very good condition without any chips. There is lovely detailed texture on the butterfly wings that resembles the natural organic patterning on real butterfly wings. The back of the brooch is signed with the Hroar Prydz hallmark and marked STERLING 9255 S Norway. It measures 50 mm x 28 mm. It weighs 8.9 grams. I have not cleaned this piece at all. As you can see in the photos, some of the gold wash is worn away but it is not noticeable from the front of the piece. Please take a moment to review the photos. I currently have several other Hroar Prydz enamel brooches listed in my shop in a range of colors, styles and sizes.
