Listed for Debra after discussing this stone specifically with her.
There is some debate over if this is weathered obsidian or a kind of tektite - my supplier is firmly of the belief it’s tektite and it has the same pitted outside that tektites have, and has a completely different feeling to me, so I lean towards the tektite belief as well. They’re found in Arizona, and are often called ’the wishing stone.’ If your intentions with it are positive, it will feed off that energy, and help amplify your positive steps to a better self, and to creating good in the world. It’s a very light, positive stone that wants to help you feel & be better.
