For my da Vinci-Inspired Cat and Mouse Necklace, I chose to focus on this playful fact and add a layer of my own friskiness. This necklace features a large cast bronze medallion impressed with the likeness of one of da Vinci’s cat drawings, and I added a hand-sculpted cast-bronze mouse connector charm above the cat to appear as if it’s stalking the mouse. The entire length of the necklace including the cat and mouse charm is about 17.5 inches, and the chain is 14k gold-filled. It can be fastened up the chain if you prefer a shorter look. It’s also available with JUST the mouse charm on a 16- or 18-inch chain.
