Raw cordierite / iolite rough pieces, approximately 2.5 to 4 cms in size. Iolite used to be used by Viking to navigate, and I personally like to wear my iolite when I wish to find direction, or, when I am open to whatever path the Universe provides that day (ie. go into town and get groceries, and follow all leads I am given).
When this stone type is more of a gem quality, it is referred to as iolite. So, technically these pieces are cordierite (the term used when they are not gem quality). I am not sure how they will react to a tumbler, but I would love to hear from anyone who has done so!
Since these stones have the energetic attributes of iolite, I have included more info here:
