Smoky Quartz Palm stones are always an easy way to get the benefits of this crystal while staying literally “in touch” with nature. These are a very deep natural colour which could be called morion quartz.
Let the crystal disperse fear, lift depression and negativity. It brings emotional calmness, relieving stress and anxiety.
Keep them beside you at your desk for rubbing with your thumb as you think. I also have had people use them for massage and for burnishing pottery before firing.
Dimensions are for the left smoky quartz palm stone which has lovely mists. The right has a fabulous rainbow.
