A vintage piece of Hattie Carnegie jewelry that is very rare. I have never seen a piece of Hattie jewelry like this one which is a gold tone metal thermometer necklace that looks so unique. This necklace has a gold tone metal necklace chain which wraps through the pendant bail connecting the chain to the amazing centerpiece. This centerpiece design is made up of a rectangular shaped gold tone metal that is made to look like a thermometer. On this thermometer is what is supposed to be a mercury filled bulb made out of glass and to the side of this are the temperature gradients reading "94, 98.6, 100, 102, 104, 106". Under this are the words "Love Meter" in large black enamel print. The back of this pendant has the signature "Carnegie" inside of a rectangular cartouche. This necklace is fastened with a spring ring clasp that holds well and the original price tag reads "Hattie Carnegie: Couture Design" on one side with the price of $3.00 on the other. The necklace measures 24" long with the pendant being 1 3/4" long by 1" in width. The necklace is in perfect condition and I question whether it has ever even been worn.
