Suppose you want to identify a gem in the most efficient manner. As a prelude to hiring a gemmologist, you could play this game to see how identification might be done. A gemmologist would couch an opinion in words like "probably" and "possibly" and "the balance of evidence." This is just a game on a website so don't take the results seriously as results, just as a possible insight into the way gemmologists work and what you can expect from them. You would do the same before you ask for legal or medical advice, right?
