Iolite is a native stone in Maine, I was lucky to find it near my home. They all are from here, except the peridot and that rough come from Arizona. Most of the sites are at least an hours drive for me, but such beautiful locations. But, it is a costly hobby now, the mines used to be open to the public once they were done mining, now it is 25.00 to 50.00 dollars to get in most of them for the day. Tourmaline from here comes in blue, green, pink, peach, red and a purple/red color. I found a beautiful piece that I faceted for my mother that was blue/green to white and then to peach.
I have collected rocks for at least 50 years, never thought I would end up faceting them too.
