GEMSTONES of the DAYS of the WEEK

The days of the week were named (in English at least) for the Sun, the Moon, and the five planets known to the ancients (or for the Roman or Norse Gods associated with those planets).

There are as many variants for the Gemstones of the Days of the Week as there are sources; no two seem to agree completely. There are consistencies, and the most common gemstones for English and several other Latin-based languages are listed here. Note that the alternate stones are consistent with the primary associated color (since the ancients sometimes called all red gems ruby, all green gems emerald, all violet stones amethyst, and so on), with the exception of Jupiter (Thor's day) which has been identified with both Sapphire and Emerald, and often with another gemstone, Cat's Eye.
