The birthstone for September is the sapphire. By tradition, it stands for faithfulness, truth and clarity. With a Mohs hardness of 9, it is the hardest gemstone after diamond, and it belongs to the star signs Virgo and Libra. And it is far from always blue: it also comes in pink, yellow, green and white.
These three pieces are the ones most often chosen with the September stone:

What the sapphire means
Hardly any stone has had as many qualities attributed to it over the centuries as the sapphire. In the Middle Ages, clergy wore it as a sign of purity and truthfulness. Travellers took it with them on their journeys as a protective stone. And in many cultures, it is regarded to this day as the stone of faithfulness, one of the reasons why sapphires are so often found in engagement rings.
What all these attributions have in common: the sapphire stands for what endures. For clarity of mind, honesty of heart and bonds that last.
For contextThe meanings mentioned are traditional symbolism from various cultures. They describe what the stone stands for and are not promises of any effect.
Not just blue: the colours of the sapphire
When it comes to sapphire, most people immediately think of a rich blue. In fact, it comes in almost every colour: delicate pink, warm yellow, fresh green, clear white. Only one colour goes by a name of its own, because in red the same stone is called ruby.
For jewellery, this means you are not tied to blue. If you prefer something more subtle, choose a light shade; if you are after the classic September look, stick with deep cornflower blue.
What our stones are made ofWe create the twelve birthstone colours with sparkling cubic zirconia, not with natural stones. As a result, the colours stay equally vivid across all months and are lightfast and suitable for everyday wear. Genuine natural stones are available in our gemstone bracelets.
Who does the September stone suit?
The sapphire is linked to two star signs: Virgo from 24 August to 23 September and Libra from 24 September to 23 October. Both are drawn to something the stone also stands for: Virgo seeks clarity and order, Libra balance and harmony.
As a gift, though, the September stone works far beyond birthdays: for the birth of a child in September, for a September anniversary, for a christening. Wherever a date plays a role, the matching birthstone tells the story as well.
More pieces with the September stone
The most popular choice is the combination of stone and engraving: the birthstone stands for the when, the engraving for the who. For each of these pieces, you choose the month yourself, so for a September birthday, that means the sapphire.

When the birthstone is the wrong choice
- If you don't know the date of birth for sure. The wrong month defeats the whole point. If in doubt, go for an engraving with a name instead.
- If a genuine natural stone is expected. Our birthstones are cubic zirconia. If you are looking for genuine sapphire, we are not the right place for you.
- As a surprise for someone who only wears gold. Check beforehand which metal colour the person already wears, otherwise the piece will go unworn.
What do you write on the card?
These are the lines our customers most often write themselves:
- Happy birthday, wishing you nothing but the best.
- A symbol of faithfulness, clarity and steadfastness.
- Stay just the way you are.
