The September Birthstone: A Complete Guide to Sapphire and Lapis Lazuli, Their Meaning, and How to Wear Them

Sapphire — focused wisdom

Lapis Lazuli — royal wisdom

September is the turn of the year toward depth. The light goes blue at the edges, the first cool evenings arrive, and thoughts grow quieter and clearer. It is the right month for a stone the color of a deepening sky.

If you were born in September, this is your guide: what your birthstone means, why Sapphire became the month's gem, how to wear and care for it, and where the ancient blue of Lapis Lazuli fits in. And, as always, which pieces from Sofia's studio might feel most yours.

What is the September birthstone?

The modern September birthstone is Sapphire — the deep, velvety blue gem long tied to wisdom, royalty, and truth. This is the answer most jewelers and friends mean when they ask about a September birthday.

September also carries an older, traditional blue: Lapis Lazuli, prized since the first civilizations. Many September lists honor both — the clear cool blue of Sapphire and the star-flecked midnight of Lapis.

The story of Sapphire

Sapphire is a variety of the mineral corundum — the very same mineral as Ruby. The two are chemically identical (aluminum oxide); trace elements decide the color. A little iron and titanium turns corundum the blue we call Sapphire; chromium would have made it a Ruby instead.

For most of history Sapphire was the stone of kings, priests, and the heavens. Medieval clergy wore it to symbolize the sky and divine favor; monarchs set it in crowns believing it protected them and attracted wisdom. It has crowned some of the most famous royal jewels in the world.

Though blue is classic, Sapphire actually occurs in nearly every color except red — pink, yellow, and the rare pinkish-orange padparadscha are all Sapphires. Our Sapphire beads are natural corundum, chosen for that deep, calm blue.

The story of Lapis Lazuli

Lapis Lazuli is not a single mineral but a rock — mostly deep-blue lazurite, laced with white calcite and glinting flecks of golden pyrite that look like stars in a night sky.

It is one of the most ancient treasures known. The Egyptians carved it into amulets and set it into Tutankhamun's funerary mask; ground to powder, it became ultramarine, the most precious blue pigment of Renaissance painting, worth more than gold. To wear Lapis is to wear a piece of the oldest human story.

What Sapphire and Lapis Lazuli mean

Both are stones of the higher mind — wisdom, truth, and clear inner vision. They are the crystals to reach for when you want to think clearly, speak honestly, and see a situation as it really is.

• Chakra: Third Eye and Throat — insight and honest expression.
• Element: Water / Wind.
• Zodiac: Virgo and Libra.
• Anniversary: Sapphire marks the 5th and 45th wedding anniversaries.

People traditionally wear these blue stones to:

• Steady and focus a busy or scattered mind
• Speak their truth calmly and clearly
• Support study, learning, and honest self-reflection
• Invite a sense of order, wisdom, and inner peace

None of this is a medical claim. It is what people have quietly written down about these stones for thousands of years.

Sapphire and Lapis in jewelry — what to look for

The two could not differ more in hardness. Sapphire scores 9 on the Mohs scale — second only to Diamond, and superb for daily wear. Lapis Lazuli is much softer at 5 to 5.5 and needs gentler care.

• Sapphire color: A rich, even blue that is neither too dark nor greyish is most prized — but any clear blue that speaks to you is a true Sapphire.
• Lapis color: Deep, saturated blue with fine golden pyrite flecks and minimal white calcite is the classic. The gold specks are natural and part of its charm.
• Cut: Faceted Sapphire beads catch light crisply; Lapis is usually polished smooth to show its color and stars.

How to wear blue every day

• Layered with gold: Both blues are stunning against warm gold — Lapis especially, since its pyrite already sparkles gold.
• Layered with silver: Cooler and more modern; silver sharpens Sapphire's blue.
• Near the throat: As Throat-chakra stones, both feel natural in chokers and necklaces close to the collarbone.
• Autumn wardrobes: Deep blue reads beautifully against camel, cream, grey, and every autumn neutral.

How to care for Sapphire and Lapis jewelry

1. Cleaning: Warm water and mild soap for both. For Lapis, wipe dry quickly — never soak it.
2. Handle Lapis gently: At Mohs 5 to 5.5 it scratches and dislikes chemicals; keep it from perfume, and store it apart from harder stones like Sapphire and Quartz.
3. Wearing: Sapphire is nearly indestructible; Lapis prefers to be taken off before swimming, showering, or heavy activity.
4. Cleansing (energetic): Moonlight or a night on a piece of Selenite suits both. Avoid salt water and long sun for Lapis.

Frequently asked questions

Is Sapphire a good birthstone gift?

Yes — Sapphire is the September birthstone and also the gem of the 5th and 45th wedding anniversaries. Its deep blue makes it a classic birthday or milestone gift.

Are Sapphires only blue?

No. Sapphire comes in almost every color except red (a red corundum is a Ruby). Blue is the classic and the one meant by September, but pink, yellow, and other fancy Sapphires are equally real.

Is Lapis Lazuli a real gemstone?

Yes — though technically a rock, not a single mineral. Its blue comes from lazurite, and the golden flecks are natural pyrite. It has been treasured as a gem for over six thousand years.

Can these stones be worn every day?

Sapphire, yes — at Mohs 9 it is extremely durable. Lapis is softer (Mohs 5 to 5.5), so wear it gently and keep it from chemicals and hard knocks.

Why is Sapphire the September birthstone?

The modern birthstone list, formalized in 1912, assigned Sapphire to September, aligning with much older associations linking the blue stone to wisdom, the heavens, and autumn's deepening sky.
