For centuries, birthstones have held a special place in jewelry, folklore, and personal identity. These gemstones are more than just pretty stones—they are symbols of individuality, history, and even spiritual significance. While most months are associated with a single birthstone, some are blessed with two or even three options. This variety reflects not only the evolving nature of gemology but also the cultural and economic factors that influence how these gems are selected and valued.
This article explores the months that have multiple birthstones, delving into their origins, symbolism, gemological properties, and the reasons behind their inclusion. Whether you're a gemstone enthusiast, a jewelry buyer, or simply curious about your own birthstone, this comprehensive guide will help you understand the significance and diversity of these precious gems.
A Brief History of Birthstones
The concept of birthstones dates back to biblical times. According to one of the oldest references, the high priest Aaron wore a breastplate adorned with 12 stones, each representing one of the twelve tribes of Israel. These stones were believed to offer protection and spiritual guidance.
Over time, these ancient symbols evolved into a system that matched each month of the year with a specific gemstone. The earliest modern list was standardized in 1912 by the National Association of Jewelers in the United States. Since then, the list has been updated multiple times to reflect new discoveries, changing tastes, and accessibility. These updates are what led to some months having multiple birthstones today.
Why Do Some Months Have Multiple Birthstones?
The inclusion of more than one birthstone for a single month is not arbitrary. It reflects several factors:
Historical and Cultural Evolution: Different cultures have historically assigned different stones to certain months. As these traditions merged and evolved, some months naturally acquired multiple stones.
New Discoveries and Availability: The discovery of new gemstones in the 20th and 21st centuries has led to the inclusion of additional stones for some months. These additions are often made to offer more affordable or accessible options.
Modern Preferences and Market Demand: The jewelry industry has adapted to consumer preferences by adding stones that appeal to different tastes and budgets. This is especially true for months with rare or expensive stones, where an alternative gem is introduced to offer a more affordable option.
Symbolism and Meaning: Different stones carry different meanings. By assigning multiple stones to a month, people can choose a gem that resonates more closely with their personality or the qualities they wish to embody.
Months with Multiple Birthstones
Let’s explore the months that have more than one birthstone, their associated gems, and the reasons for their selection.

These two stones offer a contrast in both appearance and meaning, giving March-born individuals a choice between peace and power.

Choosing the Right Birthstone for You
Selecting a birthstone is a personal decision that can be influenced by several factors:
Symbolism and Meaning: Different stones carry different meanings. For example, if you value emotional depth and creativity, opal might be your best choice. If you are drawn to strength and endurance, sardonyx or spinel might be more suitable.
Personal Connection: Some people choose a birthstone based on a personal connection—perhaps a family heirloom, a meaningful gift, or a stone that simply speaks to them.
Aesthetic Preference: The color, cut, and overall appearance of the gemstone play a role in how well it suits an individual. Some prefer bold, vibrant colors, while others prefer subtler, more refined hues.
Budget and Availability: Some birthstones, like tanzanite and alexandrite, are rare and expensive, while others, like citrine and peridot, are more affordable and widely available.
Practical Considerations: Hardness and durability are important, especially for rings and other jewelry that is worn daily. Softer stones like opal and moonstone require more care and are best suited for special occasions.
The Significance of Birthstone Variety
The inclusion of multiple birthstones for certain months is not just a matter of aesthetics or availability—it reflects the evolving nature of gemology and the jewelry industry. It allows for greater inclusivity, giving people the freedom to choose a stone that best suits their personality, preferences, and budget.
For example, the addition of alexandrite to June’s birthstone list in the 19th century provided an alternative for those who wanted a rare and unique gemstone. Similarly, the inclusion of tanzanite in December’s list in 2002 was a response to the growing popularity of this rare and beautiful stone.
These additions also reflect the global nature of gemstone trade and the influence of cultural exchange. For instance, bloodstone was added to March’s list in the UK, where it has long been associated with courage and vitality.

Understanding the reasons behind the selection of these stones adds a layer of meaning and appreciation to the gems we wear.
