Gemstones have long held a special place in human culture, symbolizing everything from love and protection to wisdom and prosperity. One of the most enduring traditions is the association of each month of the year with a specific gemstone, known as a birthstone. These stones are not only beautiful but also carry rich histories, unique gemological properties, and profound symbolic meanings. This article explores the birthstone colors chart by month, examining the key characteristics, symbolism, and practical considerations for each gemstone.
Introduction
The concept of birthstones dates back thousands of years and has evolved over time, with different cultures assigning gemstones to each month based on their spiritual, astrological, or historical significance. Today, the modern birthstone chart is widely recognized and used by jewelers, collectors, and gemstone enthusiasts. Each month is linked to one or more gemstones, and these stones are often chosen for their beauty, durability, and the meanings they carry.
The birthstone colors chart provides a visual reference for the gemstones associated with each month, along with their meanings and hardness levels. This guide is invaluable for those looking to create meaningful jewelry collections or simply understand the significance behind the stones that represent their birth months.
Historical and Cultural Significance of Birthstones
The tradition of associating gemstones with the months of the year has deep historical roots. Ancient cultures such as the Babylonians, Egyptians, and Greeks believed that gemstones had protective and healing properties and that wearing the right stone for one's birth month could bring good fortune and health.
In the Middle Ages, the concept of birthstones was further refined with the influence of religious and astrological beliefs. The biblical breastplate of Aaron, described in the Book of Exodus, is one of the earliest references to gemstones being assigned symbolic meanings. This tradition was later adapted into the Christian calendar, where each stone was linked to a specific month and zodiac sign.
The modern birthstone chart, as we know it today, was largely standardized in the 20th century by jewelers and organizations such as the American National Retail Jewelers Association. This modern list includes both traditional and newer additions, such as tanzanite and blue topaz, which reflect the evolving tastes and availability of gemstones over time.
Despite the standardization, many people still choose gemstones based on personal preference, zodiac signs, or cultural traditions. The flexibility of the modern birthstone chart allows individuals to select stones that resonate with them on a personal level, whether for their color, meaning, or aesthetic appeal.

Gemological Properties of Key Birthstones
Each birthstone has unique gemological properties that influence its appearance, durability, and suitability for jewelry. The following sections highlight the key characteristics of several prominent birthstones.
April: Diamond
- Color: Clear, white, or colored (pink, yellow, blue)
- Hardness: 10 (hardest on the Mohs scale)
- Chemical Composition: Carbon
- Refractive Index: 2.417
- Symbolism: Strength, purity, eternal love
Diamond is the most well-known birthstone, celebrated for its unmatched brilliance and durability. Its extreme hardness makes it ideal for everyday wear, and its refractive properties create the famous "fire" and sparkle that make it so desirable.
May: Emerald
- Color: Vibrant green
- Hardness: 7.5–8
- Chemical Composition: Beryllium aluminum silicate
- Refractive Index: 1.57–1.58
- Symbolism: Growth, prosperity, wisdom
Emerald is a member of the beryl family and is prized for its deep green color and clarity. Its relatively lower hardness compared to diamond means it requires more careful handling and is often protected by settings that prevent scratches.
October: Opal
- Color: Multicolored (play-of-color)
- Hardness: 5–6.5
- Chemical Composition: Hydrated silica
- Refractive Index: 1.37–1.47
- Symbolism: Creativity, hope, innocence
Opal is a unique gemstone known for its "play-of-color," which causes it to display a shifting spectrum of colors when viewed from different angles. Its lower hardness makes it more delicate and prone to damage, so it is best suited for pieces that are worn less frequently or set in protective settings.
November: Topaz
- Color: Yellow, orange, blue
- Hardness: 8
- Chemical Composition: Aluminum silicate fluoride hydroxide
- Refractive Index: 1.61–1.62
- Symbolism: Positivity, abundance, energy
Topaz is a versatile gemstone available in a wide range of colors. Its high hardness and clarity make it a popular choice for jewelry, especially rings and pendants. The golden topaz is particularly associated with warmth and joy, making it a fitting birthstone for November.
December: Tanzanite
- Color: Blue-violet
- Hardness: 6–7
- Chemical Composition: Calcium aluminum silicate
- Refractive Index: 1.69–1.70
- Symbolism: Transformation, healing, spiritual growth
Tanzanite is a relatively new addition to the birthstone list, discovered in Tanzania in the 1960s. Its striking blue-violet color and pleochroism (the ability to show different colors when viewed from different angles) make it a captivating gemstone. While it is not as hard as some other birthstones, its beauty and rarity contribute to its popularity.

Practical Considerations: Care and Cleaning
Proper care and cleaning are essential for maintaining the beauty and longevity of gemstones. The care requirements vary depending on the gemstone's hardness, chemical sensitivity, and structure.
High-Hardness Gemstones (Diamond, Ruby, Sapphire)
Gemstones with high hardness (8–10 on the Mohs scale) such as diamond, ruby, and sapphire are generally durable and can withstand daily wear. They can be cleaned with warm, soapy water and a soft brush. Ultrasonic cleaners are also safe for these stones.
Medium-Hardness Gemstones (Emerald, Peridot, Opal)
Gemstones with medium hardness (6–7.5) such as emerald, peridot, and opal require more careful handling. They can be damaged by harsh chemicals, extreme temperatures, or physical impact. It is best to avoid ultrasonic cleaners and instead use a soft cloth and mild soap for cleaning.
Low-Hardness Gemstones (Pearl, Moonstone)
Gemstones with low hardness (2.5–6) such as pearl and moonstone are delicate and require gentle care. They should be kept away from acidic substances and excessive moisture. Cleaning should be done with a soft cloth and lukewarm water. These stones are best suited for occasional wear and should be stored in a dry, cool place.
