Birthstones have fascinated people for centuries, serving as both beautiful adornments and meaningful symbols tied to one’s birth month. These gemstones, each with its own unique properties and lore, have been used in jewelry and personal adornment across various cultures and historical periods. This article provides an in-depth exploration of birthstones, including their origins, the changes in their association over time, and their modern significance in contemporary gemology and jewelry.
Introduction
The concept of birthstones dates back to ancient times, where specific gemstones were believed to hold symbolic and protective powers for those born in a particular month. Over time, the list of birthstones has evolved, with various additions and modifications made by professional organizations such as the American Gem Trade Association and the Jewelry Industry Council of America. Today, birthstones are not only treasured for their aesthetic appeal but also for their historical and cultural significance.
This article will delve into the history of birthstones, the evolution of their associations with specific months, and the gemological properties that make them unique. We will also examine the symbolic and metaphysical beliefs attributed to these stones and their role in modern jewelry and gift-giving traditions.
History and Origin of Birthstones
The use of gemstones as birthstones has its roots in ancient religious and cultural traditions. One of the earliest references to gemstones associated with specific months is found in the Bible, in the Book of Exodus, which describes the breastplate of the High Priest adorned with twelve gemstones representing the twelve tribes of Israel. While these stones were not explicitly linked to birth months, this early association of gemstones with specific groups and meanings laid the foundation for the development of the birthstone tradition.
The modern concept of birthstones as we know it today began to take shape in the 18th and 19th centuries in Europe, where the practice of associating gemstones with birth months became increasingly popular. This tradition was later introduced to the United States, where it gained widespread acceptance. In 1912, the American National Association of Jewelers (now known as Jewelers of America) officially adopted a standardized list of birthstones for each month. This list was later updated in 1952 by the Jewelry Industry Council of America to reflect changes in gemstone availability and cultural preferences.
In 2002, the American Gem Trade Association added tanzanite as an additional birthstone for December, and in 2016, spinel was added as an alternative birthstone for August. These additions reflect the evolving nature of the birthstone tradition and the ongoing efforts to incorporate new gemstones that are both beautiful and accessible to a wider audience.
The Modern Birthstone List
The modern birthstone list includes a total of 12 gemstones, each associated with a specific month of the year. While the majority of these associations have remained consistent over time, some months have multiple gemstones due to the addition of alternative options. These additions are typically made by professional gemological organizations to provide more variety and to accommodate changes in the availability of certain gemstones.
The following is a list of the modern birthstones for each month:
- January: Garnet
- February: Amethyst
- March: Aquamarine
- April: Diamond
- May: Emerald
- June: Pearl, Moonstone, Alexandrite
- July: Ruby
- August: Peridot, Spinel
- September: Sapphire, Lapis Lazuli
- October: Opal, Tourmaline

Each of these gemstones has its own unique properties and symbolic meanings, making them valuable not only for their beauty but also for their cultural and historical significance.
