I been doing rather alot of research on the Rose Quartz stone. It claims to have metaphysical properties that can heal anxiety. Is this true? And if not, can it get rid of muscle twitching and aches?
I don't know, but not very much.
My (random) guess is about 1,000-3,500 dollars for the 4 by 4 one.
Very little. Quartz is so common to find that its almost worthless. You could probably only fetch a decent amount of money if it was really nice, colourful and beautiful
