Re: Think I have a big chunk of rough turquoise? Help
Kelsey; Looks more like chrysocolla than turquoise to me . touch a spot to your tongue if it sticks its probably chrysocolla or at best chalk turquoise. Don't make a habit of this but now and then won't hurt. Most every person who I know who works with turquoise uses this test once in a while. If the idea of tasting the rock bothers you wet a finger and you can feel it stick slightly.
