This awesome kaleidoscope necklace by Luc and Sallie Durette is as beautiful on the outside as it is on the inside. The kaleidoscope is made from sycamore and cedar woods. The inlay art work has an Aztec appearance. The interior has a 2 mirror system with flamed worked glass pieces in an oil filled cell. The oil filled cell is a separate turning mechanism from the kaleidoscope. The cord is adjustable so you can wear it at different lengths. Just pull the metal clasps to adjust the length. The longest total length of the cord is 30". The kaleidoscope is 3 1/4" long, 1" wide and 1/2" thick. The cell is 7/8" in diameter. This is a great kaleidoscope to keep in mind for that special lady in your life. A great Christmas present too!!
