Understanding Your Birthstone

Understanding Your Birthstone

1. What is a birthstone?

Birthstones are precious or semi-precious gems that are traditionally associated with each month of the Gregorian calendar. The origins of this tradition trace back to the Breastplate of Aaron described in the Book of Exodus, which contained twelve specific stones representing the twelve tribes of Israel.

2. Traditional vs. Modern

In 1912, the National Association of Jewelers met to standardize the list of birthstones, creating what we now call the "Modern" list. This list features:

  • Clarity and Color: A focus on transparent, brightly colored stones.
  • Accessibility: Gems that are more easily available to jewelers.
  • Alternatives: Adding secondary stones to months like June (Alexandrite/Pearl) and October (Opal/Tourmaline) to offer aesthetic choices.

3. Zodiac Connections

While birthstones are linked to the calendar month, astrological signs bridge two months. Determining your exact sign requires both your month and day of birth, tying your planetary influences to your gemstone's unique energy.

Frequently Asked Questions

Common questions about gemstones and birthstones.

Over time, jewelers have updated the standardized list to include more readily available or less expensive alternatives, or stones with different physical characteristics (like durability) to offer consumers more choices.

Modern birthstones are universally based on the calendar month you were born in. However, historical traditions often assigned stones directly to the twelve signs of the Zodiac.

Historically, many ancient cultures believed that wearing your birthstone during its assigned month heightened its therapeutic or mystical powers, providing luck, health, or protection.

Absolutely! In fact, in ancient times it was common to own a set of twelve stones and wear a different one each month to maximize their purported benefits year-round.
