Gem is a beautiful love implication. It can be seen that the boy mentioned by the subject is very generous, and gems are also very valuable objects, and there are many kinds. The boy mentioned by the subject may love this girl very much, but he just doesn't know why they are all green. Maybe he didn't buy a hat, of course, it may be that green gems look better and have many colors, but I hope the subject can identify the composition of the gems. Maybe he's a girl.
