September’s Birthstone: Sapphire
If diamonds are forever, sapphires are unforgettable. Rich in colour, steeped in history, and effortlessly chic, sapphires have long been the gemstone of choice for queens, icons, and anyone who wants their jewellery to whisper “I’m different.”
For those born in September, it’s your birthright to shine in sapphire. For the rest of us, it’s simply an excuse to fall in love with one of the most coveted gemstones in the world.
Royal Roots & Modern Muses
Sapphires have always had a seat at the table of power. Medieval kings wore them for protection, and royalty through the ages have adored them for their symbolism of loyalty and wisdom. Of course, the most famous sapphire of modern times is Princess Diana’s engagement ring, now worn by the Princess of Wales, Kate Middleton.
But sapphires aren’t just for royals. Today’s style muses, from red-carpet stars to cool girls layering fine jewellery with denim, prove that sapphires are just as at home in a modern wardrobe as they are in a crown vault.
Not Just Blue
When you think “sapphire,” you probably picture that iconic, velvety royal blue. But here’s where it gets exciting: sapphires actually come in a rainbow of colours. Blush pinks, sunshine yellows, mysterious greens, dreamy teals, even the rare “padparadscha” sapphires with their fiery pink-orange glow.
This makes sapphires the ultimate gemstone for personal expression. Classic navy blue is timeless. But a peach-pink sapphire in rose gold? That’s a moment.

Strong, Sexy, and Practical
Here’s another reason we adore sapphires: they’re tough. Literally. Second only to diamond on the hardness scale, sapphires are made for everyday wear. Which means your sapphire engagement ring or cocktail ring isn’t just breathtaking—it’s built to last. Consider it your permission slip to actually wear your jewellery every day (instead of keeping it locked away for “special occasions”).
How We Style Sapphires

At The Diamond Expert, sapphires are a favourite for bespoke commissions. Their versatility is unmatched, and you can pair a deep blue sapphire with white diamonds for timeless glamour. Or opt for a stunning pink sapphire set in yellow gold for something unexpected and fresh.
We’ve designed sapphires as striking solitaire engagement rings, as earrings, or pendants in remodelled heirlooms. No two sapphires are the same, and that’s the magic of them!
Sapphire Ideas for September (and Beyond)
Thinking of making sapphire part of your story? Here’s some inspiration:
- The statement ring – a sapphire centre stone surrounded by a halo of diamonds (think red-carpet energy).
- The modern pendant – a pink sapphire paired with a diamond for cool-girl chic.
- The remodel – breathe new life into an inherited piece by setting a diamond with a sapphire to add colour and character
-
The proposal ring – a non-traditional but unforgettable sapphire promise ring that will be worn on another hand after the engagement ring
A Final Word
Sapphires aren’t just beautiful, they’re a vibe. They’ve got history, personality, and strength. They make an entrance without trying too hard. If September is your month, wear your birthstone with pride. If it’s not, treat yourself anyway! Because some rules are made to be broken, and sapphires were made to be worn.
At The Diamond Expert, we’ll help you find your sapphire - the one that feels like it was always meant for you.
