I fell in love with the colors in this large stone. It's small white dot demanded pairing with moonstone, as an echo or reflection of the moon on rippling waters. I enjoy creating pendants by designing as I carve the wax to enhance the stones making a piece that is enjoyed on both sides. I am not sure if this is a natural stone. I thought it was a calsite but it is probably rainbow calsillica, which is a man made composition. Some people don't like man made or stabilized stones, I always try to be honest with my customers.
