Source Tradition

In Hellenistic astrology as codified by Ptolemy's Tetrabiblos (ca. 150 CE), Aries is the exaltation of the Sun and the house of Mars—the first sign of the tropical zodiac, associated with the vernal equinox. The bloodstone (heliotrope) connection arises from March's traditional birthstone assignment, while diamond entered through the Jewelers of America 1912 standard for April-born Aries individuals.
