Pick a stone you are attracted to....
You probably think you are choosing the stones for aesthetic reasons, some believe that intuitively you are attracted to the stone for its metaphysical benefits. Following this line of thought, People will choose the stones they need.
In other words, let the stone choose you.
Gemstones are thought of by many as Mother Nature's natural healers and are a delight to give and receive.
By gifting someone with a gemstone you may also be offering a healing.
To be clear, healing gemstones are not medicine. They will not actually improve a medical diagnosis. But if you believe in them, they might improve your mood and emotional wellbeing (which is wonderful).
I believe gemstones can work with the mental, emotional, or spiritual discord that can cause, at least in part, illness in the body and not the physical illness itself.
All you have to do is believe...
