Melissa Etheridge Necklace - Black Onyx with Key Logo

This is a one-of-a-kind, special made Melissa Etheridge necklace. I took it to a jeweler and he said it was made of black onyx. It has Melissa's key logo in purple outlined in silver. It was given to me a few years ago by someone who had designed it and had it special made for them in Amsterdam, The Netherlands. The pendant is 3/4" long and 1/2" wide. It has the key logo on the front and two silver rows of leaves going around it. The back has nothing on it. The silver chain hangs about 12". It's a beautiful piece of jewelry that any Melissa fan would love to have. I accept money orders and PayPal. Insurance is optional. Thank you.
