I'm drawn to the emerald, blood stone, aquamarine, lapis(for obvious reasons), green aventurine. and pretty much all the rest of them. The prices are certainly a factor.
If you needed physical healing what would you get and why. I've ordered their books for now. But i do know the power of stones. If these really concentrate more energy then they would be worth it by all means. Any millionares want to buy me an emerald string?
