Not accurate definitely don’t pay
It gave me 4 choices for each gem and some wildly out. Eg showing g a black tourmaline for a pale blue gem. It identified 50% of my collection only because I already knew what they were. It didn’t recognise my Jade, garnet, lapis lazuli any clear ones, blue correctly or any brown correctly. If I didn’t know what it was then no hope. The sodalite is white but on the app shows as a blue gem. No option to search for correct one. I did like it saving the photo in a collection but deleted the app as it is sadly useless.
