Historical healing properties

It would be a nice stone, sweet but it must be carefully chosen and apply the correct shade on the right chakra. Which is difficult because there are only found slices of mixed colors.
It should be for not pubescent girls, adolescents because it is very soothing.
The green smithsonite should be used on the heart chakra and would have soothing qualities.
