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.

Birthstones. For the "sign stones" which are based upon the astrological
signs (constellations) of the Zodiac, see Zodiac Birthstones.
