Teachers who know diamonds, please show me if this diamond is real.
Wow, where did you buy it? How many cards do you need? You can't tell whether this picture is true or not. Ask yourself where you got it. If it is picked up and got from others, it is estimated that the chance of really drilling is very small. If you are a rich man and can afford tens of calories of diamonds per minute, the chances of actually drilling are very high.
