What Is the Birthstone for September?
Sapphire is one of the most sought-after and well-known gemstones in the world. It is the birthstone for September. Sapphire is a rare stone that is part of the corundum mineral family. It is known for its incredible shine, great hardness, and famous blue color that moves the spirit.
Most people think of a deep, velvety blue when they think of sapphire. However, this gemstone can be found in almost every hue of the rainbow, from gentle blush pinks and bright yellows to lush greens and delicate purples. You won't find a sapphire in this color: Red because red corundum is called ruby, which is a different name.
For a long time, people have linked sapphire with the sky, truth, and good character. People thought for hundreds of years that the sky was a huge sapphire that the Earth rested on. Today, it is still one of the "Big Four" precious stones, along with diamonds, rubies, and emeralds. And with good cause. It is absolutely one of a kind because of how beautiful, strong, and full of meaning it is.
If you were born in September, you are lucky to have this famous diamond as your own.

September Birthstone History & Meaning
The history of sapphire is as deep and complex as the stone itself. It goes back thousands of years and crosses religions, civilizations, and royal courts.
In ancient Persia, kings thought that the Earth was on a huge sapphire and that the sapphire's reflection made the sky blue. This cosmic link made sapphire much more valuable than other gems. It wasn't just pretty; people thought it represented a piece of the divine order of the cosmos.
The Greeks and Romans of old thought that sapphire was connected to Apollo, the god of light and prophecy. People who went to the Oracle at Delphi to ask for help would wear sapphires in the hopes that Apollo would like them and give them clear, honest replies. This is why people have long thought of the gemstone as a symbol of truth, clarity, and knowledge.
Sapphire was the gemstone of choice for both clergy and nobility throughout the Middle Ages. People thought that sapphires might bring blessings from God, protect the wearer from jealousy, and even work as an antidote to poison. Catholic bishops wore sapphire rings as signs of purity and a connection to heaven. Sapphires were used by kings and queens to decorate their crowns and other royal items, making the stone a sign of power, loyalty, and holy authority.
The 12-carat oval blue sapphire that used to belong to Princess Diana and is currently on Catherine, Princess of Wales's engagement ring is probably the most renowned sapphire in contemporary history. That one piece of jewelry brought back people's interest in sapphires over the world and made them a new symbol of love.
Sapphire stands for many important things nowadays, such as honesty, loyalty, knowledge, and dignity. It is also the customary present for 45th wedding anniversaries, which shows how it is a stone symbolizing lasting love and loyalty. For babies born in September, wearing their birthstone is more than just a fashion statement; it's a link to thousands of years of human history and meaning.
September Birthstone Color
When people say "sapphire blue," they're talking about a color that is very well-known in the gemstone world. It's a rich, velvety medium-to-deep blue that looks like it has the whole ocean in it. But the universe of sapphire color is much bigger and more complex than just that one famous color.
Blue sapphires are evaluated on three key characteristics: hue, saturation, and tone. The most prized blue sapphires display a pure, vivid blue or slightly violet-blue with strong saturation and medium tone — not too light that they appear washed out, and not so dark that they lose their sparkle. The most celebrated examples of this ideal color come from Kashmir, and their velvety, cornflower-blue quality is considered the pinnacle of sapphire beauty.
Beyond blue, sapphires come in an array of stunning colors, collectively called fancy sapphires:
-
Pink Sapphire — Romantic and feminine, ranging from soft ballet pink to hot fuchsia
-
Yellow Sapphire — Warm and radiant, evoking sunshine and optimism
-
Padparadscha Sapphire — A rare and highly prized pinkish-orange variety, named after the lotus blossom
-
Purple Sapphire — Rich and mysterious, straddling the line between royalty and romance
-
Green Sapphire — Fresh and earthy, a more understated alternative for those who love nature-inspired tones
-
White Sapphire — Colorless and brilliant, often used as a diamond alternative
There is also the magical color-change sapphire, which shifts hue depending on the light source appearing blue under natural daylight and purple or violet under incandescent light. This extraordinary optical phenomenon makes color-change sapphires among the most fascinating stones in the gem world.
For September birthdays, the classic blue sapphire remains the definitive choice — but if you or your recipient has a personality as colorful as the gemstone itself, a fancy sapphire in their favorite color makes for an extraordinarily personal and meaningful gift.
September Birthstone Durability
Sapphire is one of the most beautiful stones, but its hardness and endurance make it one of the best options for exquisite jewelry.
Gemologists all around the globe use the Mohs scale of mineral hardness as a standard. Sapphire has a grade of 9 out of 10. Diamond is the only natural material that is tougher than sapphire. It is a perfect 10. Sapphire is exceedingly hard, almost like a diamond, which makes it exceptionally resistant to scratches from regular use. This is an important attribute for gemstones that are set in rings and bracelets that get a lot of wear and tear.
Sapphire is tough, which means it doesn't crack or break easily when put under strain. This makes it far tougher than many other gemstones. Because it doesn't have cleavage (the tendency of some stones to split along internal planes), it is strong enough to handle the stresses of everyday living.
This combination of hardness and toughness makes sapphire an ideal stone for
-
Engagement rings — It can withstand years of daily wear without losing its polish or brilliance
-
Bracelets and bangles — Pieces that knock against surfaces frequently
-
Everyday earrings and pendants — Jewelry worn in all conditions, from workday to weekend
Because sapphire is so strong, it is also employed in industrial settings, such as the crystal faces of luxury timepieces and the lenses of high-end cameras. Sapphire jewelry is made to endure a lifetime and beyond, so when you wear it, you're wearing a gemstone that is built to last.
September Birthstone Origin
Sapphire can be found on almost every continent, but the best ones come from a few famous places, each with its own unique look and reputation.
Kashmir, India In gemology circles, the term Kashmir is used with great respect. The sapphires from this isolated part of the Himalayas, which were mined in the 19th and early 20th centuries, are thought to be the best ever found. Their amazing velvety, cornflower blue color, which comes from tiny particles that scatter light in a way that is very soft, has never been copied. Today, true Kashmir sapphires are quite hard to find, and stones of a known Kashmir origin sell for very high sums at auction.
Burma (Myanmar) The Mogok Valley in Myanmar has been making beautiful sapphires for hundreds of years, along with its famous rubies. Burmese sapphires are noted for their deep, bright blue color with a hint of violet. Stones with "Mogok" certification are among of the most sought for on the market.
Sri Lanka (Ceylon) Sri Lanka has been mining sapphires for more than 2,000 years, which is why it is known as "Gem Island." People appreciate Sri Lankan sapphires, which used to be called Ceylon sapphires, for their lighter, brighter blues. They have a gentle, cornflower color that is both elegant and easy to wear. The country also makes a lot of fancy sapphires, such the pretty padparadscha type.
Madagascar Since the late 1990s, Madagascar has been one of the world's top producers of sapphires. Today, it supplies a large part of the global sapphire market. Malagasy sapphires come in a wide range of colors and qualities. Some of the best stones are as good as those from classic sources.
Australia Most Australian sapphires come from Queensland and New South Wales. They tend to be darker, inkier blues with a hint of green. They are strong, easy to find, and a great value, even if they are not often compared to Kashmir or Burmese materials.
Montana, USA Montana makes sapphires that are only found in the United States. These stones can be steel blue, teal, greenish-blue, or even a mix of colors. People really like Yogo Gulch sapphires from Montana because they are naturally beautiful and have a bright, clear blue color.
Each sapphire origin has its unique geological mark, and for collectors and experts, the stone's provenance is a very important part of its identity and value.
September Birthstone Care & Maintenance
Sapphire is one of the easier-to-care-for gemstones since it is so hard. However, like any fine jewelry, it needs frequent, careful care to keep its beauty and brilliance for generations.
Cleaning Your Sapphire Jewelry
The safest and most effective way to clean sapphire jewelry at home is with warm water, a small amount of mild dish soap, and a soft-bristled brush a soft toothbrush works perfectly. Gently scrub around the stone and setting to dislodge any oils, lotions, or everyday buildup that can dull the stone's brilliance. Rinse thoroughly under warm running water and pat dry with a soft, lint-free cloth.
For a deeper clean, ultrasonic cleaners are generally safe for untreated or heat-treated sapphires — which covers the vast majority of sapphires on the market. However, if your sapphire has been fracture-filled or treated with oils or resins (which is less common but does occur), ultrasonic cleaning can damage those treatments. When in doubt, ask your jeweler about your stone's specific treatment history before using an ultrasonic device.
Steam cleaning is also safe for most sapphires, though again, treated stones should be approached with caution.
Storing Your Sapphire Jewelry
Despite sapphire's hardness, it can scratch softer gemstones and metals if stored haphazardly. Store sapphire jewelry separately in a soft pouch or a lined jewelry box compartment to prevent contact with other pieces. This protects both your sapphire and the rest of your collection.
Everyday Wear Tips
-
Remove sapphire rings before activities involving heavy impact, harsh chemicals, or prolonged water exposure (swimming pools, for instance, contain chlorine that can affect metal settings over time)
-
Apply perfume, lotion, and hairspray before putting on your jewelry — these substances can build up on the stone's surface and diminish its luster
-
Remove sapphire jewelry before engaging in gardening, gym workouts, or household cleaning
Professional Maintenance
Even with careful home care, it's worth having your sapphire jewelry professionally inspected and cleaned once a year. A qualified jeweler will check the security of prongs and settings ensuring your precious stone is held safely and can give the piece a professional polish that restores its original brilliance.
With proper care, a sapphire piece doesn't just last a lifetime — it becomes an heirloom, carrying its beauty and meaning forward from one generation to the next.
