Prehnite is considered the stone of unconditional love a d to heal the healer. Calms the environment and gives protection. One of the reasons I bought it was that I was drawn to it without knowing the meaning behind this stone. I think its pretty cool. It is 14 K gold over sterling silver which is why I decided to give it up as my skin is super sensitive and the chain is a little itchy when I tried it on after I bought it. Its all one piece so I can’t switch out for a diff necklace . So now it has sat in drawer , never worn for 2 yrs with a couple other pieces. My loss is your gain! Gorgeous piece with a beautiful meaning behind the stone !
