Gemstones have long held a unique place in human culture, symbolizing everything from status and wealth to spiritual protection and romantic love. Among the many traditions that have developed around gemstones is the concept of birthstones, gemstones associated with specific months of the year. While most months are associated with a single birthstone, a select few months are distinguished by having multiple gemstones assigned to them. This article explores the months that have three birthstones—January, June, May, and December—and the reasons behind their selection. We will also examine the historical, cultural, and gemological significance of these stones, drawing on centuries of tradition and modern gemological insights.
Introduction
Birthstones are more than just decorative elements in jewelry; they are deeply rooted in history, religion, and cultural symbolism. The idea of assigning a gemstone to each month of the year can be traced back to ancient times, with one of the earliest references found in the Breastplate of Aaron, as described in the Bible. This artifact, which bore twelve gemstones, was believed to represent the twelve tribes of Israel and, by extension, the twelve months of the year. Over time, the tradition evolved, and today, the modern birthstone calendar includes not just one gemstone per month, but sometimes multiple—most notably for January, May, June, and December.
This article will explore the months that have three assigned birthstones, highlighting the historical origins of this tradition, the gemological properties of each stone, and the cultural symbolism that has been attributed to them. We will also examine how these gemstones have been incorporated into jewelry and what makes them special in terms of rarity, color, and meaning.
History and Lore of the Three-Birthstone Months
January: A Month of Abundance
January is unique in that it has three traditional birthstones: garnet, emerald, and rose quartz. The inclusion of multiple gemstones for this month may reflect the abundance of natural resources and the long-standing fascination with gemstones in early human history.
Garnet has been a popular gemstone since ancient times. Used by the Egyptians, Greeks, and Romans, it was often worn for protection and to ward off negative energies. Garnet is a silicate mineral that occurs in a wide range of colors, though red is the most common and well-known.
Emerald, a green variety of beryl, was also used in ancient times and was highly prized for its deep, vibrant color. Emeralds have been mined in Egypt as early as 330 BCE and were considered symbols of fertility and rebirth.
Rose quartz is a pink variety of quartz and has been associated with love and emotional healing. Its use in jewelry dates back to the Egyptian and Roman civilizations, and it remains a popular choice for those seeking to express affection and care.
These three gemstones reflect the diversity and richness of January’s symbolism—ranging from protection and passion to love and renewal.
May: The Month of Emeralds and More
May is another month with three birthstones: emerald, chrysoprase, and agate. The inclusion of multiple gemstones for this month suggests a desire to offer a range of choices that reflect the varied aspects of springtime—growth, vitality, and beauty.
Emerald, as mentioned earlier, is a gemstone of deep green color and has been treasured across cultures for its rarity and beauty. It is often associated with wisdom and sincerity.
Chrysoprase is a green variety of chalcedony that has a more subtle, moss-like color. It was historically used in Roman and Egyptian jewelry and is believed to promote emotional balance and clarity.
Agate, a type of chalcedony, comes in many colors and patterns. It is known for its grounding properties and was used in ancient times as a protective stone. Agate was also believed to help with digestive and respiratory health.
The three gemstones of May reflect the themes of growth and renewal associated with the arrival of spring, making this month a symbol of new beginnings.
June: A Month of Duality and Modernity
June is another month with three birthstones: pearl, alexandrite, and moonstone. Unlike the other months with multiple birthstones, June's selection includes both traditional and modern additions.
Pearl is one of the oldest known gemstones and is unique in that it is the only gemstone formed from organic material. Pearls are created within mollusks and have been revered for their beauty and elegance for centuries. In ancient times, they were believed to be the tears of the gods or the brain of a dragon.
Moonstone, a type of feldspar, is known for its ethereal glow and has been associated with intuition, femininity, and calm. It was a popular gemstone in Victorian-era jewelry and continues to be a symbol of mystery and serenity.
Alexandrite, the youngest of the three, was discovered in the 19th century and is prized for its color-changing properties. It appears green in daylight and red under incandescent light. This unique characteristic made it a favorite among gemstone collectors and jewelry designers.
The inclusion of these three gemstones in June reflects both the ancient reverence for pearls and the modern appreciation for color-changing gemstones like alexandrite.
December: The Month of Rarity and Richness
December, like January and May, is also associated with three birthstones: turquoise, zircon, and tanzanite. These gemstones represent a blend of tradition and modernity, with some being used for centuries and others being discovered more recently.
Turquoise has been used for thousands of years in jewelry and ceremonial objects. It is a blue-green mineral that has been found in Egypt, Persia, and the Americas. It is believed to bring protection, good fortune, and healing.
Zircon, a silicate mineral, is known for its brilliance and comes in a variety of colors, including blue, green, and red. It was historically used in jewelry and was sometimes mistaken for diamonds due to its high refractive index.
Tanzanite, the newest addition to the birthstone list, was discovered in Tanzania in the 1960s. It is a violet-blue gemstone that is extremely rare and is often associated with transformation and spiritual growth.
December’s three gemstones represent a spectrum of colors and meanings, making it a fitting choice for a month that marks the end of the year and the anticipation of new beginnings.

Gemological Properties and Care
Understanding the gemological properties of each birthstone is essential for both collectors and jewelry wearers. These properties determine how the gemstone should be handled, cleaned, and stored to maintain its beauty and value.
Hardness and Durability
The hardness of a gemstone is measured on the Mohs scale, which ranges from 1 (softest) to 10 (hardest). The following are the hardness ratings for the gemstones associated with the months that have three birthstones:
| Gemstone | Mohs Hardness | Notes on Durability |
|---|---|---|
| Garnet | 6.5–7.5 | Generally durable but can be scratched by harder materials. |
| Emerald | 7.5–8 | Susceptible to fractures and should be handled with care. |
| Rose quartz | 6–6.5 | Relatively soft and can be easily scratched. |
| Chrysoprase | 6.5–7 | More durable than rose quartz but still requires gentle handling. |
| Agate | 6.5–7 | Very durable and suitable for everyday wear. |
| Pearl | 2.5–4.5 | Very soft and can be easily scratched or damaged. |
| Alexandrite | 8.5–9 | Extremely durable and suitable for jewelry. |
| Moonstone | 6–6.5 | Sensitive to heat and can be scratched easily. |
| Turquoise | 5–6 | Relatively soft and prone to cracking if exposed to dry environments. |
| Zircon | 6–7.5 | Generally durable but can be brittle in some varieties. |
| Tanzanite | 6–7 | Sensitive to heat and can fade if exposed to direct sunlight. |
Chemical and Physical Stability
Each gemstone has unique chemical and physical properties that affect its stability and care requirements.
Pearls are especially sensitive to chemicals, including perfumes, lotions, and cleaning products. They should be cleaned with a soft cloth and stored in a dry, cool place to prevent damage.
Emeralds contain inclusions and are prone to cracking. They should be cleaned with warm water and a mild detergent and should never be exposed to harsh chemicals or high heat.
Alexandrite and moonstone are sensitive to light and should be stored in a dark place when not being worn to prevent fading or discoloration.
Turquoise can lose its color if exposed to dry environments or strong chemicals. It should be kept in a cool, humid place to maintain its appearance.
