I’ve been seeing the stones that come from a site known as “Wild Whetstones”. The owner/operator goes by Gabriel. He’s products seem to get great reviews, but they seem to be mostly limited to his site. The story behind the stones sounds good, but I’m just not sold yet. Was hoping to get some feedback from the group here. Anything new tends to make me hesitant on making a new purchase. But I do have to say, the idea of a neck pendant natural stone does sound kinda cool.
