After reading some of the reviews I was a bit worried that the rock would be too small or whatever.  I ordered the sodalite rock and the crystal necklace sold by the same company.  Both were HUGE!!  Much bigger than I anticipated with very rich colouring.  I love them both.  I was hoping for the free bracelet others talked about but instead I got crystal attached to a key chain that may actually be bigger than the one Im wearing around my neck!  Very impressed.
