This is the one where a spot was filled in.

This is the part where spots seem gouged out.

This is just a general picture of what the slab looks like without imperfections.

''Imperfections'' do not exist in natural stone. Natural stone has variations that include pits, fissures, voids, cracks, and crystal popouts. That is all 100% normal. Some of that can be mitigated by man made fill, aka resin impregnation, but that does not imply that the normal state of a fragile decorative stone is ''defective''. That's a human concept, based on faulty ideals that mother nature does not attempt to achieve.

"Am I justified in complaining?"

No.

"Any point asking them to try to repair?"

None.

"Should I possibly ask them to replace it (not that I'd count on them to do so - I've already paid in full ) ?"

No.

You've gotten exactly what you've paid for.

Your fixes don't seem that terrible to me. If the filled spots are not the same sheen or the color is off and the fixes are very noticeable, I would ask them to come out and do a better job. Hopefully, all the movement in the stone hides the imperfections.

Thank you everyone. These are exactly the responses I was looking for. I just wasn't sure if this was normal. Hearing that it is. Thank you again.

your stone is absolutely beautiful. As gorgeous as that stone is, I doubt anyone would notice any 'imperfections'.
