It is best to use the heat guide and magnifying glass to identify diamonds. The thermal guide has a thermal guide effect, and then use the magnifying glass without double shadows. That must be a diamond. has no thermal guidance effect, it is definitely not a diamond. has a double shadow, which is silicon carbide.
