This is a fabulous 18k yellow Gold and Plique-à-jour Enamel and Rubies Butterfly Brooch Pin. The butterfly's eyes are rubies, round cut, 0.05 cts. The 18 k gold butterfly's wings show five beautiful colors: blue, turquoise, egg white (very light blue), green, and red. Plique à Jour jewelry has a miniature stained glass window effect. The wings are movable to various 3D positions that allow various light effects of the color. Frames of metal hold enamel with no backing, thus allowing the light to come through. The size is about 2 1/2" x 1 5/8" (63mm x 39mm). A jeweler's marker and "18K Spain" are stamped on the back. Total weight is 8.8 grams. This signed jewelry is in pristine condition.
