Here, again, there are almost as many opinions as there are authorities, but the following list expresses a consensus:
Sun: Diamond, ruby, carbuncle.
Moon: Crystal, pearl, opal, moonstone; all milk-white stones.
Mercury: Quicksilver, loadstone.
Venus: Emerald and, possibly, sapphire.
Mars: Bloodstone, flint, malachite, red haematite.
Jupiter: Amethyst, turquoise.
Saturn: Garnet, jet, all black stones.
Uranus: Chalcedony, lapis lazuli, jacinth, amber.
Neptune: Coral, aquamarine, ivory.
Pluto: Beryl and, presumably, sardonyx; jade, cloissone enamels, ceramics.
It should be realized that all stones, precious and semi-precious, as stones, come more or less directly under Saturn, the overall ruler of all hard minerals. As for many, authorities differ so widely that to settle the question each stone would have to be examined with respect to its mineral components before deciding the planet to which it should rightfully be assigned.
Planetary Metals.
Sun: Gold
Moon: Silver, aluminum
Mercury: Quicksilver
Venus: Copper, brass
Mars: Iron, steel.
Jupiter: Tin.
Saturn: Lead.
Uranus: Radium, uranium.
Neptune: Lithium, platinum.
Pluto: Tungsten, plutonium.
