accessories to other stones, would it not perhaps be better to omit the

and worn from ancient times.
"Astral
stones" or "zodiacal stones" are terms used to designate those gems
which were believed to be peculiarly and mystically related to the

from March 21 to April 20, and so on down to Capricornus, which begins
