Alison Jean Cole is a "lifelong rock nerd and geology guide" living in the Pacific Northwest. She spends a great deal of time traveling throughout the western states "in search of cool rocks to chop up, I particularly love colorful rocks and will also dig some out of buckets in rock shops, too." She is a proud member of the Mt. Hood Rock Club and teaches lapidary arts.
All pieces are crafted in her Portland, Oregon studio, "I take large chunks of rough material to cut into slabs on a really big rock saw. Then the shapes are trimmed out of the slabs on a smaller rock saw. I use successive grits to polish each stone by hand on a rudimentary faceting machine. The process is arduous but rewarding.
