You can flip a coin to change its face, but it remains the same coin.

Discovering that I was adopted redefined my entire world, but it taught me that who you are doesn't change.

I am almost inclined to coin a word and call the appearance fluorescence, from fluor-spar, as the analogous term opalescence is derived from the name of a mineral.

Don't you think it's strange that life, described
as so rich and full, a camel-trail of adventure,
should shrink to this coin sized world?
