Each stone represents a planet from the solar system which are carefully selected and polished to resemble the colours and textures of the planets. Crystals include howlite, red jasper, imperial jasper, picture jasper, red network jasper, tiger's eye, amazonite, lapis lazuli and hematite, with each crystal stored in a drawstring bag for an out-of-this-world gift for someone special. As each crystal is unique, stone shape and colour may vary from photos shown.
