More precious than gold, but cannot be bought,
Can never be sold, only earned if it's sought,
If it is broken it can still be mended,
At birth it can't start nor by death is it ended.
Above all things have I been placed
Thus have I, a man disgraced.
I describe sunlight or lock
But after all, I'm just a rock.
We are emeralds and diamonds,
Lost by the moon;
Found by the sun,
And picked up soon.
