You are looking at a shiny silver tone Mood charm with gold trim. The color-changing section of the charm in this auction is shaped in a rectangle and starts out black.
As your mood changes, so does the color of the heart. Black indicates that you are Excitable, green means Sensitive, amber is Nervous, blue/green indicates that you are Calm, amber/green means you are Troubled and dark blue means Happy & Love.
Please note that although there are 4 mood rectangle charms in the picture, these are photographs of the same charm taken at different times to show the variety of color changes. The listed price is for only one rectangle mood charm. However, you can purchase additional charms if they are available.
What a great gift or why not add it to your own bracelet?
