Gold

The best or most valuable in yourself or in opportunity. A part of you that lasts, that is eternal; what stands the ‘acid test’ or does not tarnish with time, in terms of personal qualities, such as love, patience or care in work; something you value or want in your life.

If cheap or false: Something you valued but does not deserve respect.

If tarnished: Something beautiful and valuable in yourself, perhaps your spirit, that you have let become soiled.
