This article provides a detailed and accurate overview of the colors of birthstones by month, drawing on authoritative gemological and historical sources. We will explore the modern and traditional birthstones for each month, their symbolic meanings, their physical properties, and how they are used in jewelry today.
History and Lore of Birthstones
The tradition of assigning gemstones to specific months is ancient, with roots in both biblical and cultural lore. One of the earliest known references to birthstones appears in the Breastplate of Aaron, described in the Old Testament (Exodus 28:15–30). This sacred Jewish artifact was said to contain twelve gemstones, each representing one of the twelve tribes of Israel. While the exact identities of these ancient gemstones remain debated among scholars, the concept of associating gemstones with specific times of the year has persisted through the ages.
In medieval Europe, the use of gemstones for their supposed magical and healing properties became widespread. During this period, various gemstones were believed to offer protection, enhance health, and bring good fortune. These beliefs were often intertwined with the calendar and the zodiac, leading to the development of the modern birthstone tradition.
Today, the association of gemstones with specific months has evolved into a widely accepted practice, with each stone representing unique traits and symbolism. The modern birthstone chart, as we know it, was standardized in the United States in the 1950s by the American National Association of Jewelers (now known as the Gemological Institute of America). This chart combines both traditional and modern interpretations, offering a rich tapestry of gemstone choices for each month.
The Modern and Traditional Birthstone Chart
The modern birthstone chart is a culmination of centuries of tradition and contemporary gemological advancements. While some months have a single birthstone, others have multiple options. For example, June and December each have three birthstones, while October and November have two each. This flexibility allows individuals to choose a stone that resonates with them on a personal level.

Care and Cleaning of Birthstones
Proper care and cleaning of birthstones are essential to maintain their beauty and longevity. The care instructions vary depending on the type of gemstone and its physical properties. For example, gemstones with a lower hardness, such as pearls and opals, require more delicate handling and cleaning methods, while gemstones with a higher hardness, such as diamonds and rubies, can be cleaned with more vigorous methods.
When cleaning gemstones, it is important to use a soft cloth and mild soap. Avoid using harsh chemicals or abrasive materials, as they can damage the surface of the gemstone. For gemstones with inclusions or fractures, it is important to avoid soaking them in water, as this can cause the inclusions to expand and weaken the stone.
For gemstones with a high hardness, such as diamonds and sapphires, it is safe to use ultrasonic cleaners. However, for gemstones with a lower hardness, such as pearls and opals, it is best to avoid ultrasonic cleaners, as the vibrations can cause damage to the stone.
When storing gemstones, it is important to keep them in a cool, dry place away from direct sunlight and other gemstones. This helps to prevent damage from heat, moisture, and friction.
