I have been lucky, to have bought a few sphere crystals from, this company, ALL of them, are great, from the small ones, to the medium one, which is Quartz transparent, to me, all round and great to the touch and eye. I like the small ones, better, since there are many and because I handle them, more often, on a regular basis, during the week. I like the choices in colors and materials, in general. I have, small, medium and a large one, so far, I might buy one big one again, made from the purple crystal, I forgot the name, right now, I do not have the book, with me, at this moment. Amethyst, I think is the one!!
Overall, the Sphere Ones, win the Day for me, I like the pointed ones, also, buy, the Sphere ones, are better, nicer for ME!!! Regards, alberto
