September Birthstone: A Guide to Sapphire Colors, Meaning and Care

Long valued for its depth of color, durability and symbolism, sapphire has become one of the most enduring and widely worn birthstones in fine jewelry. Best known for rich blue tones, sapphires also appear in a range of colors, offering long-lasting style suitable for everyday wear in modern jewelry.

While carnelian and lapis lazuli are recognized as alternative September birthstones, sapphire remains the primary stone associated with the month. In this guide, we explore the characteristics and care of sapphires, with tips for selecting a piece for everyday wear or to celebrate your love on a special occasion.

Sapphire is the primary birthstone for September. In recent years, carnelian and lapis lazuli have also been recognized as alternative September birthstones, however the sapphire remains the most widely accepted choice today.

Sapphire belongs to the corundum mineral family, which is known for its extreme durability. Ranking 9 on the Mohs hardness scale, sapphire resists chips and scratches better than most colored gemstones. This strength makes the sapphire birthstone a popular choice for rings, earrings and other jewelry designed for regular wear.

The comparison below highlights the differences between sapphire and other September birthstones:

The most recognized September birthstone color is blue, with the blue sapphire serving as the classic representation of the month. The rich, saturated blues make it a distinct and highly sought after gemstone in fine jewelry.

That said, sapphire isn’t limited to one shade. Trace elements present during formation gives sapphires a wide range of hues and saturation levels, appearing in a variety of colors including pink, purple, green, or yellow. These variations influence both appearance and price, giving buyers flexibility when choosing a stone that fits their style.

Carnelian is known for its warm orange-red tones, while lapis lazuli features deep blue shades marked by gold-colored flecks. Together, these gems show how the September birthstone color spectrum can extend beyond blue, even though sapphire remains the traditional birthstone for the month.

Common Sapphire Colors

Sapphires span a broad color spectrum, giving the September birthstone visual range without sacrificing durability.

• Blue sapphire: The classic and most recognized option, ranging from deep royal blue to cornflower blue
• Light blue sapphire: Softer tones that often appear lighter and may be more affordable
• Teal sapphire: Blue-green hues that feel modern and visually distinctive
• Padparadscha sapphire: A rare pink-orange variety valued for its unique, sunset-like color

Types of Sapphire

In addition to color, sapphires are categorized by optical effects and formation traits that influence how each stone looks.

• Fancy sapphires: Pink, yellow, green, purple, and colorless sapphires, often identified by the stone’s color name
• Bi-color sapphire: A single stone displaying two distinct colors, often blue-green or yellow-green
• Color-change sapphire: Appears blue in daylight and shifts to violet or purple hues under different lighting
• Star sapphire: Displays a star-shaped reflection, known as asterism, when properly cut and viewed under direct light

Sapphire symbolizes loyalty, truth and nobility. This is why royalty and clergy wore them as emblems of authority and divine favor, particularly in ancient Europe and Asia. 

Carnelian is linked to courage, motivation and confidence, often associated with vitality and personal strength. Lapis lazuli represents truth, wisdom and self-expression, valued for its deep blue color and longstanding use in art and spiritual objects.

Color also plays a role in the September birthstone meaning. Different sapphire hues are often associated with distinct qualities, such as:

• Blue sapphire birthstone styles are commonly linked to calm focus, loyalty and long-term commitment
• Lighter blue or teal sapphires can feel softer and more modern, with a relaxed visual presence
• Nontraditional sapphire colors, such as pink or yellow, often express individuality while retaining durability for everyday wear

These gemstones reflect a broad emotional range tied to September. The sapphire birthstone remains a thoughtful choice among the most popular gemstones for engagement rings and fine jewelry.

Sapphires are sourced from a limited number of regions around the world, where geological conditions allow corundum formation. Historically, some of the most well-known sources include Kashmir, Myanmar (formerly Burma) and Sri Lanka. Sri Lanka has long been recognized for producing sapphires with particularly vivid color and high transparency.

More recently, additional deposits have been discovered across Australia, Thailand, Cambodia, Madagascar, India, and the United States, particularly Montana. While sapphire appearance can vary by location, all sapphires share the same fundamental properties, regardless of geographic location.

Sapphire jewelry spans a wide range of price points, influenced by color, carat weight, treatment and quality. 

• Color: Even, saturated blue tones are most highly valued. Lighter or nontraditional hues often offer greater pricing flexibility.
• Carat weight: Larger sapphires increase in price as fine color and clarity become rarer at higher weights.
• Treatment: Heat treatment is common and accepted. Untreated stones often carry a premium due to scarcity.
• Setting and metal: A sapphire set in 14k gold will differ in cost from one mounted in platinum. Accent diamonds and halo designs also increase the overall investment.

Colored gemstones, including sapphires, are evaluated using the 4Cs to describe appearance. However, they are not assigned overall quality grades like diamonds. Gemological organizations such as the Gemological Institute of America (GIA) document a stone’s features to help buyers evaluate and compare individual sapphires.

Reports may also include information about a sapphire’s origin and whether it has been treated, such as through heat enhancement to improve color or clarity. These details are typically disclosed to provide additional context about how the stone was formed and prepared for sale.

The 4Cs of Sapphire Grading

• Color: Color is the most important factor for sapphires and is evaluated based on hue, tone, and saturation. Even color distribution and strong saturation are particularly valued.
• Clarity: Sapphires often contain inclusions. Stones with fewer or less visible inclusions tend to appear clearer and more visually appealing. However, inclusions do not automatically indicate poor quality.
• Cut and shape: Describes how a sapphire is shaped and faceted. Sapphire is often cut with a brilliant pattern on the crown (top) and a step-cut pattern on the pavilion (bottom).
• Carat weight: Measures the sapphire’s weight rather than size. Larger sapphires are increasingly rare, particularly in fine color and clarity combinations.

Although well-suited for regular wear thanks to its durability, sapphire benefits from routine care to help maintain its appearance over time. Professional cleaning is recommended periodically, especially for pieces worn often or set with accent stones, as a jeweler can safely clean and inspect the setting for looseness or wear.

For regular upkeep at home, sapphire jewelry can be cleaned using gentle methods that won’t damage the stone or setting. Avoid harsh chemicals or abrasive cleaners, and always handle your jewelry with care to help maintain its appearance.

How to Clean Sapphire Jewelry at Home

1. Add warm water into a small bowl with a small amount of mild soap.
2. Soak your sapphire jewelry for about 20 minutes. If your jewelry has heavier buildup, let it soak longer.
3. Next, brush the gemstone with a soft-bristled toothbrush and rinse the jewelry with clean water.  
4. Be sure to thoroughly dry the gemstone with a soft towel.
5. Do not allow the water to stay sitting on the gemstone.

Sapphire is a versatile gemstone that works across a wide range of jewelry styles and occasions, valued for balancing visual impact with everyday practicality. Whether chosen to celebrate a September birthday, mark a proposal, reflect personal taste, or serve as stylish gifts for bridesmaids, sapphire jewelry adapts easily to different moments and meanings.

When deciding on a piece, consider the following factors:

Color preference and saturation

Deep, evenly saturated sapphires tend to appear richer, while lighter or pastel hues offer a softer, more understated look. The wide color range makes it easy to align the stone with the recipient’s personal style or overall aesthetic.

Jewelry type and lifestyle

Although striking in statement pieces, sapphire is well-suited for rings, bracelets and earrings worn often. Its durability is one reason it’s used in sapphire engagement rings, including the iconic sapphire ring worn by Princess Diana.

Setting considerations

Bezel and halo settings enclose more of the sapphire’s edges, offering greater protection for jewelry worn regularly. Prong settings leave more of the stone exposed, emphasizing color and light but requiring more care during wear.

With its versatility and enduring symbolism, sapphire is a natural choice for meaningful jewelry. As the September birthstone, it has wide appeal for birthday celebrations to those  exploring diamond alternatives for engagement rings.
