I will add a sterling silver chain…people sometimes like to add their own chain. Blue tourmaline is sometimes known as indicolite, please see links. Pink tourmaline with blue Big artisans sterling silver India, as an afterthought I decided to add more pictures and was amazed that one of them came out with a pink pyramid inside of it in the shape of a house. I thought this might be a sign, because I have had some experience with reading tea leaves, my mother could read them and I tried my hand at it once for a professional gypsy psychic. He was listening to me very seriously. Because I have to move again for the 10th time in 20 years, very reluctantly! Can the house that came out in the picture that I do not see in the stone be a message for me? What do U see?
