How Blue Sapphire Became the September Birthstone
The blue sapphire, a gemstone of illustrious beauty and rich historical significance, was not always the designated birthstone for September, but its journey to this honored position is fascinating.
Historically, different cultures attributed unique gemstones to various months and zodiac signs, such as the virgo gemstone for those born under the Virgo zodiac sign.
Over time, the allure of the sapphire’s deep blue hue and its revered qualities became universally acknowledged, leading to its official designation as September’s birthstone. This was solidified by the Jewelers of America and the American National Retail Jewelers Association in 1912.
Today, blue sapphire stands as a symbol of wisdom and prosperity for those born in September, embodying qualities of loyalty, clarity, and nobility. Its storied past and celestial appeal continue to inspire wonder and admiration.
Physical Properties of Blue Sapphire
Blue sapphire, a variety of the mineral corundum, owes its striking hue to trace amounts of titanium and iron within its structure. This majestic gemstone ranks an impressive 9 on the Mohs scale of hardness, making it second only to diamond in terms of durability.
Its remarkable hardness makes sapphire suitable for everyday wear and ideal for various types of jewelry. The gemstone’s inherent toughness ensures it can withstand the rigors of daily life.
Blue sapphire possesses exceptional clarity, which is a crucial factor in determining its value and appeal. High-quality sapphires are typically free from inclusions visible to the naked eye.
Another notable feature of blue sapphire is its pleochroism, the ability to display different colors when viewed from different angles. This unique characteristic adds to its allure, complexity, and depth.
In addition to its visual attributes, blue sapphire has extraordinary thermal stability, allowing it to endure high temperatures without compromising its structural integrity. This property highlights its suitability for use beyond just adornment, extending into industrial applications.
Conclusively, the synthesis of hardness, clarity, pleochroism, and thermal resilience makes blue sapphire not only a gemstone of great beauty but one of remarkable physical resilience. These attributes underscore why it is esteemed as the September birthstone.

How to Identify a Genuine Blue Sapphire
Identifying a genuine blue sapphire involves assessing the stone’s color, clarity, cut, and origin. These characteristics are paramount.
In 2016, gemologists developed advanced techniques, including spectroscopy, which helps determine the stone’s authenticity by analyzing its internal structure, and detecting synthetic counterparts.
Color, the most crucial aspect, should exhibit a vibrant blue that is neither too dark nor too light. A genuine sapphire typically displays a velvety or velour-like texture under various lighting conditions.
Clarity and inclusions in the gemstone also indicate authenticity. Unlike flawless synthetics, natural stones often possess minor imperfections visible under magnification, which authenticate their natural origins.
By considering these factors, you can ensure the blue sapphire you select is both genuine and of high quality.
Caring for Your Blue Sapphire Jewelry
Blue sapphires are known for their strength and durability but still require diligent care to maintain their splendor.
Regularly clean your sapphire jewelry with lukewarm water, mild soap, and a soft brush. Avoid harsh chemicals or ultrasonic cleaners.
When not in use, store your blue sapphire pieces separately from other jewelry to prevent scratches. A soft pouch or cloth is ideal.
Professional inspections are advisable at least once a year. This ensures that settings remain secure and any wear and tear is promptly addressed.
By following these care guidelines, your blue sapphire jewelry will retain its brilliance for years to come.
Sapphire Investment Value and Collecting Tips
Sapphires are not only treasured for their beauty but also valued as long-term investments. When considering sapphires as an investment, several key factors influence their value:
- Color: The most valuable sapphires exhibit vivid, saturated hues. For blue sapphires, a deep, velvety blue is most prized. Fancy sapphires are valued for their intensity and rarity of color, with padparadscha and vivid pinks commanding premium prices.
- Clarity: High-quality sapphires have excellent clarity with minimal visible inclusions. However, some inclusions can confirm a stone’s natural origin and add character.
- Cut: A well-cut sapphire maximizes brilliance and color. Precision cutting enhances both beauty and value.
- Carat Weight: Larger sapphires are rarer and more valuable, especially when combined with exceptional color and clarity.
- Origin: Sapphires from renowned locations like Kashmir, Burma (Myanmar), and Sri Lanka often fetch higher prices due to their legendary quality and historical significance.
- Treatment: Untreated sapphires are significantly more valuable than treated stones. Always request certification from a reputable gemological laboratory.
Collecting Tips:
- Buy from trusted jewelers who provide full disclosure on treatments and origin.
- Request a certificate from a recognized gemological lab (such as GIA or AGS).
- Consider investing in rare colors or origins, as these tend to appreciate over time.
- Store sapphires securely and insure valuable pieces.
By understanding these factors, collectors and investors can make informed decisions and enjoy both the beauty and the potential financial rewards of owning fine sapphires.

Known as “fancy sapphires,” these gems can be found in pink, yellow, green, orange, purple, and even colorless varieties. The only color you won’t find in sapphire is red, as red corundum is classified as ruby.
Fancy-colored sapphires are increasingly popular for those seeking a distinctive twist on the traditional September birthstone. Pink sapphires, for example, symbolize love and compassion, while yellow sapphires are associated with prosperity and joy. The rare and coveted padparadscha sapphire, with its delicate blend of pink and orange, is especially prized among collectors.
When choosing a sapphire for a September birthday, consider exploring these vibrant alternatives. Fancy sapphires offer the same durability and brilliance as their blue counterparts, making them ideal for everyday wear and custom jewelry designs. Whether set in rings, pendants, or earrings, non-blue sapphires provide a personalized and meaningful way to celebrate a September birthday.
