@SilverBear has a sharp eye and talent with crystals! They sure can be hard to identify- I love your idea about an app for identifying them, @nadialuna. It seems to be unfortunately common for shops and sellers to mislabel the stones they sell. Like the discussion about Is Selenite Really Selenite?
I’ve tried ordering from sites like AliExpress and Amazon with very mixed results. For anyone looking to add some lovely Amazonite or other stones to their collection, I’ve found it’s worth it to spend a bit more and invest in stones from a specialized shop!
