Polishing compound can not be cleaned off by you or I, or even a jeweler.
It requires boiling in acid by a qualified facility that polishes diamonds.
I assume they will remove the diamond from the setting before doing this.
To determine if it is internal or gunk on the surface use a loupe or microscope.
They use focus to establish if it is internal or on the surface.
Because of diamond's high index of refraction (their ability to change the angle of light a great deal) they can play tricks with where we think inclusions are.
Sometimes they can even make one inclusion appear several times.
Where can I buy a loupe (assuming I want to do it today in person and not online)?
