I have to start with this. After making this necklace I read up a bit on a pack of rats. It is with pure joy that I share with you that a pack of rats is also called a MISCHIEF! It's so perfect, and so is this necklace I hand-carved. I love making often thought of unpleasant things into beautiful jewels. I am a lover of rats, and I have found through making the Rats Collection that so are many of you. Dimensions: The pack measures 1 3/4 inches long and a millimeter over 1/2 inch wide. The chain measures 18 inches long. Materials:Silver Tone: white brass charm on a stainless steel chainGold Tone: brass charm on a gold plated stainless steel chainSterling Silver: sterling silver charm, chain, and parts14K Gold Plate: sterling silver charm, chain, and parts plated entirely in 14K gold. The base metals I use (Silver Tone and Gold Tone) used are both 100% brass. White brass is a metallic alloy that is made of copper and zinc. There is no nickel in any of our jewelry. For more information on the metals I use, please see the FAQ's. All my jewelry is hand made by me, Karen Yost, in my NYC studio at the time of purchase.
