Can a jeweler tell if a diamond is lab created?

How can you tell if a diamond is real from a picture?
Using magnification, look at the gemstone through one of the bezel or star facets on the crown. If the stone shows doubling, which means it looks like there are two of each facet line, then it is probably a moissanite. If you see only one of each facet line and it passed the heat test then it may be a natural diamond.
