History and Lore of Birthstones
The concept of assigning gemstones to each month is ancient, with roots in both cultural and spiritual traditions. One of the earliest references to birthstones comes from the Breastplate of Aaron, a sacred artifact described in the Hebrew Bible. This breastplate was said to contain 12 gemstones, each representing one of the 12 tribes of Israel and aligned with the zodiac signs of the month.
Over time, the association of gemstones with the months evolved. In medieval Europe, gemstones were believed to have protective and healing properties, and people often carried or wore their birthstone to harness its powers. These beliefs were especially strong in the context of astrology, where the position of the moon and the stars was thought to influence one's fate and personality.
By the 20th century, the modern birthstone list was standardized, though it continued to evolve. For example, alexandrite was added as the birthstone for June in the 1950s due to its rarity and unique color-changing properties, while tanzanite was introduced in the 1960s as another option for December.
Today, birthstones are not only cherished for their symbolic value but also for their beauty and durability. They remain a popular choice in jewelry and are often given as meaningful gifts for birthdays and anniversaries.
Modern and Traditional Birthstone List
While the modern birthstone list is widely recognized and used today, the traditional list includes different gems that were historically significant. These traditional stones are sometimes still used in jewelry, especially in regions where they are more readily available or less expensive. Below is a comparison of the modern and traditional birthstones by month:
| Month | Modern Birthstone | Traditional Birthstone |
|---|---|---|
| January | Garnet | Garnet |
| February | Amethyst | Amethyst |
| March | Aquamarine | Bloodstone |
| April | Diamond | Diamond |
| May | Emerald | Emerald |

| September | Sapphire | Sapphire |
| October | Tourmaline | Opal |
| November | Citrine, Topaz | Topaz |

Some months have multiple modern birthstones. For example, August includes both peridot and spinel, while December includes tanzanite, blue zircon, and blue topaz. This flexibility allows individuals to choose the stone that appeals to them most or is more readily available in the market.
The traditional stones, such as bloodstone for March and opal for October, are often less known but still hold historical and symbolic significance.

Caring for Your Birthstone Jewelry
To ensure that your birthstone jewelry remains beautiful and lasts for years, it’s important to care for it properly. Here are some general guidelines based on the gemstone's properties:
Hardness and Toughness: Softer stones like opal and pearl should be handled with care and not exposed to harsh chemicals or impacts. Harder stones like diamond, ruby, and sapphire are more durable but still require proper cleaning and storage.
Cleaning: Most gemstones can be cleaned with a soft cloth and mild soap and water. Avoid using ultrasonic or steam cleaners for stones with fractures, inclusions, or porous surfaces (like opal and turquoise).
Storage: Store gemstone jewelry in a soft-lined jewelry box or individual pouches to prevent scratching. Avoid stacking stones or exposing them to direct sunlight for long periods, especially for stones that may fade or change color.
Avoiding Damage: Remove jewelry before swimming, bathing, or applying lotions and perfumes. Some gemstones can be sensitive to heat or chemicals, so it's best to avoid exposing them to these elements.
By following these care tips, you can preserve the beauty and value of your birthstone jewelry for generations.
