hi. i recently purchased a rose quartz and an amethyst pyramid (really small ones). what i wanted to know is how do i energize them?? i know what each stone mean and that is why i purchased them. when i picked these particular ones i felt good so i bought them. also is it necessary to be in constant contact of the stone to make it work as in will it be better if i wear a bracelet of these stones instead?? thankyou.
