Would these black specs significantly reduce the price of this ruby? Im sure it can be a really subjective issue. I was just wondering. It is a heated mozambique ruby.

Can't tell if it is heated, but any eye visible inclusions greatly reduce value. Of all inclusion types black spots are probably one of the worst.

i should pobably cut off the top and bottom, might add to the fire and possible hide those black spots.

Could be Amphibole Crystals, metal sulfide crystals, chromite crystals, Mica, all of which are common in Rubies from Mozambique.
