You know there's varying opinon between crystal healers on whether or not the size does matter. My feeling is that a small crystal has the potential to work just as well as a large crystal with the right intent behind it. So, you know, lots of people through things like "The Secret," have been introduced to the idea that thoughts are things and our thoughts are very powerful. So crystals, the energy in them, is really sort of relatively innert until you put your intention and focus into them. So you can have a great big 20 pound piece of Rose Quartz, but if you don't have an intent or a purpose for using that it's not really going to do any good for you. Whereas if you have a tiny little stone in your pocket, but you have a thought or intention behind how that stone is going to help you for healing, that's what really creates this sort of transformational healing energy that most people are looking for when it comes to stones.
