I used it on quality specimens that I already have identified and it was wrong 90-98% of the time. Location map is difficult to impossible to use. Recommend that you try the free trial or purchase only 1 week before doing a 1 year subscription. Already cancelled my 1 year. Essentially useless. ## Frequently asked questions about STONE IDENTIFIER gem & rock id ### How does STONE IDENTIFIER identify rocks?
