Just wanted to say thanks for the stones you sent. They arrived quickly and well packaged. Had wanted to comment sooner but wanted to work with them for a while first. Interesting! I don't know if it is a placebo effect or what, but I will say that when I meditate with them, my concentration and ability to focus are better than when I attempt to meditate without them. Really like your website. Easy to navigate and lots of great stones to check out. Also lots of really valuable, interesting information about stones & their uses. Really appreciate that! Like to spend lots of time at your site just looking at everything. Thanks again & I hope to do business with you again!
