I would not but now I'm worrying massively cause I sent a sapphire to GIA and it came back as a pad. Damn, the stone and cert were over 1000 dollars. I was hoping to either resell or keep as a possible mini investment... is GIA notoriously easy going with premium labels?

No, they are not, this and the 'paraiba' posted here are not the norm for GIA.
But I don't think their color gradings hold more weight than what my eyes see.
Did the stone come back as treated and if yes what kind?
I would trust a GIA color grading over GRS, AIGS and a handful of other labs, but I would prefer AGL or SSEF. I find AGL and SSEF have the strictest color/designation system - just from casual observing, I'm not an expert.
Its not an exact science... Sometimes labs disagree with each other, not just color/designation but also origin and treatment. I believe there was a case GIA graded a synthetic alexandrite as natural, which was later found out to be synthetic by AGL.
People can disagree with labs too...Some think the padaradscha label can only apply to Sri Lanka origin stones. I once saw a fancy sapphire with an AGL report that I think deserved a padparadscha designation, but AGL detected a brownish modifier.
If you have photos of the stone that are mostly color accurate I'm sure people would provide opinions. If you start a new thread more people might take notice.
This is an excellent writeup on the padparadscha color designation - there are disagreements even between dealers based on an informal/mini experiment (figure 11):
