Scheelite as a diamond imitation has been surpassed by more convincing products, like [[cubic zirconia]] and [[moissanite]], synthetic scheelite is occasionally offered as natural scheelite, and collectors may thus be fooled into paying high prices for them. [[Gemology|Gemologists]] distinguish natural scheelite from synthetic material mainly by microscopic examination: Natural material is very seldom without internal growth features and inclusions (imperfections), while synthetic material is usually very clean. Distinctly artificial curved striae and clouds of minute gas bubbles may also be observed in synthetic scheelite.

The visible [[absorption spectrum]] of scheelite, as seen by a hand-held (direct-vision) [[spectroscope]], may also be of use: most natural stones show a number of faint absorption lines in the yellow region of the spectrum (~585&nbsp;nm) due to [[praseodymium]] and [[neodymium]] trace impurities. Conversely, synthetic scheelite is often without such a spectrum.
