These pretty Palm stones measures 7cm x 5cm.
You may not get the exact palm stone in the photo but it will be similar, some have a few more dark blue lines running through them, some the lines are finer - but I always chose pretty ones.

In simple Crystal Healing, Blue Crystals are associated with the Throat Chakra.
When this Chakra is out of balance we can experience feelings of depression, the need to control others, dishonesty and lack of flow in communication. Sometimes this can manifest in physical problems with speech.
When the Throat Chakra is healthy and balanced we feel centered and happy and our communications flow smoothly and positively.
