Either something anti-climactic, when the gem fails to produce any effect, or something very dramatic, if, say, massive amounts of magic energy are focused through it and the inauthentic stone proves utterly unable to handle even a fraction of that power, exploding into a terrible magical botch and/or razor sharp shards of manufactured diamond.
