Now this is just me & my experience.
Have had all three of these stones in my jewelry collection for years. Rings, pendants, beads & wands. Way, way before the general public was into this kind of thing & way before opaque stones in general were popular.

I have noticed absolutely no difference in how I feel, physically or mentally.

Before you spend alot of money, wait for some more opinions on here & try alittle more research on internet.

Good luck, ya never know.
