This is the coolest necklace for someone who likes astonomy! Here we have the nine planets laid out in beads: Mercury, Venus, Earth and Moon, Mars, Jupiter, Saturn, Neptune, Uranus, and yes, Pluto. Tiny black beads represent outer space with tiny shiny silvertone beads representing the stars! Mercury is made from chalcedony, Venus a simulated pearl, Earth is ocean jasper dyed blue, the Moon is now labradorite (found only in Labrador, Canada!), Mars is ocean jasper, Jupiter is synthetic malachite, Saturn is mother-of-pearl and/or calcite, Uranus is opalite, Neptune is purple crackle agate, and little Pluto is fire agate dyed light blue. Comes in a nice white gift box with ARThouse logo; people often give this as a gift!
