The zodiac is a belt-shaped region in the sky extending about 8° north and south of the ecliptic, the Sun’s apparent path across the celestial sphere over the year. This belt includes the Moon and the brightest planets in their orbital planes. The zodiac is divided into 12 equal parts, each covering 30° of celestial longitude, and these parts correspond to the constellations Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, and Pisces. Historically, these signs have been used to mark times of the year, with each sign associated with specific days when the Sun is in that part of the sky. In Western astrology and former astronomy, these signs are linked to various attributes.
The zodiacal system, with its 360° angular measurement, originated in Babylonian astronomy during the 1st millennium BC and was later incorporated into Greek astronomy and the Hindu zodiac by the 2nd century BC. Due to the precession of the equinoxes, the period the Sun spends in each constellation has shifted since Babylonian times, moving the March equinox point from Aries to Pisces. The zodiac forms a celestial coordinate system, specifically an ecliptic coordinate system, with the ecliptic as the latitude origin and the Sun’s position at the vernal equinox as the longitude origin. Modern astronomy still uses this system to track objects within the Solar System.
Discover the Magic of Birthstones: A Timeless Tradition in Jewelry
At first glance, the idea of birthstones and zodiac stones might seem like a clever marketing tactic designed to entice you into buying gems tied to your birth month or zodiac sign.

The Origin of Birthstones: A Journey Through History
Let’s delve into the fascinating origins of modern birthstones. Many gem scholars trace the concept back to the Bible, specifically to the Breastplate of Aaron. Aaron, Moses’ brother and the first High Priest of the Israelites, wore a ceremonial garment adorned with twelve distinct gemstones representing the twelve tribes of Israel. These stones, each made from a specific mineral and inscribed with a tribe’s name, are described in the Book of Exodus. Due to the passage of time and numerous translations, the exact identification of these stones remains debated, with many scholars suggesting they translate to today’s Carnelian, Peridot, Emerald, Garnet, Lapis Lazuli, Quartz, Yellow Zircon, Banded Agate, Amethyst, Citrine, Onyx, and Green Jasper.
Evolution of Birthstones: From Breastplate to Modern Jewelry
The connection between the twelve stones of Aaron’s Breastplate and the twelve months of the year led to the birthstone tradition we know today. In the 5th century, St. Jerome suggested using the twelve gemstones mentioned in Revelation to represent each month. By the 17th century, the custom of wearing the gemstone attributed to one’s birth month year-round became popular, evolving into the modern birthstone tradition. Today, birthstone lists vary globally, reflecting cultural differences and historical changes.
