What a certificate does not say
A laboratory report is a set of answers to a specific set of questions. Knowing which questions were not asked is most of reading one well.

A report states species and variety, weight and measurements, and a treatment determination. Depending on the laboratory and the tier of service, it may state an origin opinion. These are the answers. They are reliable, and they are narrow.
What a report does not do is tell you whether the stone is well cut, whether the colour holds across lighting conditions, or whether the price makes sense. Those are judgements, and no laboratory offers them. A buyer who treats the report as a complete description of the stone has outsourced the interesting part.
On origin opinions
Origin determination is an opinion based on inclusion scenes and trace-element chemistry, expressed with a confidence the report does not always make legible. Two competent laboratories can disagree about the same stone. This is not a scandal; it is what inference under uncertainty looks like.
We name the laboratory on every stone for exactly this reason. Which lab issued an opinion is part of the information, not a detail to tidy away.
