Regarding the myths that crystal could amplify, boost or enhance the luck have been barely shown by scientifically measurement of vibration energy and conductive characteristic. But luck is not measurable.
Human body composed of carbon, water elements, atoms, molecules, cells and yes, its just biological machine...and then installed with our soul...with intelligence and justification. The energy come from food we eat are for the function of biological machine, whereas "the diet" for our mental is usually neglected.
I don't know how crystal could actually enhanced the luck or improve the life but there are list of crystal stones with various kind of claimed attributes. Based on my Ba Zi (data of birth date and time), I have not enough of fire element and therefore crystal with fire element and also with emotional stabilizing effect will be suitable for myself...
After 4 hour of careful selection and consideration, I got my Agate Star of David necklace, Red Agate wrist band and Rutile wrist band. Agate mainly for health, social, relationship, talent, balanced the body ion charge and stabilized emotion Rutile for wealth accumulation, balanced and stabilized temper and emotion.
If luck really can be bought, cost of these crystals and the consultation would be very worthy.
I'll see..
p/s: the necklace went missing not even a week...haha...hope someone pick it will have good luck as me! !#@$!$@
