The season of spring, with the first flowering of the reborn year, is considered especially appropriate for the amethyst, the green diamond, the chrysoberyl, the spinel, the pink topaz, the olivine, and the emerald. The bright sun of summer, that bells the fruit and spreads the foliage, is best for zircon, garnet, ruby, and fire opal. Spinel, chrysoberyl, and pink topaz still hold their charm. As the languors of summer tang toward the crispness of autumn, it grows time for sapphire, hyacinth, oriental chrysolite, tourmaline, jacinth, and topaz. Then with the challenge of winter come turquoise, white sapphire, rock crystal, quartz, moonstone, pearl, and the gleaming diamond. Of course, the brilliant solitaire, the diamond of the engagement ring, is an appropriate stone in any season. _The Days of the Week_ The days of the week are more intricately bound in gemmed symbol. If you know the day on which you were born, you can garner all the good fortune that comes with the proper stone. Each day of the week, along with the stone, bears other significances and powers. _Sunday_ The golden-yellow day of King Sol, the sun, is marked with the yellow jacinth. If one wears this, we are told, one has the power of a lion on that day—especially when Leo, the lion in the heavens, takes the summer season with the sun. But also this is a token of secrecy in the man—it ensures discretion, always advisable, often essential, in a lover—while in the woman it betokens generosity, always desired but not always appreciated by a lover. _Monday_ The serene day of the moon is the day for pearls. Pearls should be bestowed on a Monday. The color white is bound with them and with the day, for the snow-white blanket of peacefulness. A man might wear a pearl in a tie clasp, bar, or in a tie pin, which is coming back into favor. The pearl is a token, in a man, of friendship, of integrity, of a religious feeling; and in a woman of contemplation, purity, affability. _Tuesday_ Tuesday is a more active day. Tiw is the Nordic god of war, and his name is used to translate the Latin for Mars’ day. Hence its stone is the blood-red ruby. This is a fitting day to hold in memory those who have died valiantly in battle. But it is likewise a day to be on one’s guard, for while the star ruby marks nobility and power of command in the man, it may also spill over in excess to bloody vengeance. And in the woman, while the ruby of this day adorns a proper pride, it may descend to a pettier obstinacy. At its best, the ruby is resplendent on a Tuesday. _Wednesday_
