Every Month Has a Gemstone Made Just for You
Do you believe gemstones carry a kind of energy? Across cultures and centuries, people have linked each month’s births to a specific stone, a birthstone believed to bring health, good fortune and protection. These aren’t just beautiful minerals; they carry centuries of meaning and intention.
July, August and September sit at the transition between high summer and early autumn, and the three birthstones that correspond to these months are as distinct and vivid as the season itself. If you’re searching for a gift with genuine significance, or want to weave your love story into something tangible, read on.
Curious about earlier months? You can explore the January, February and March birthstone guide and the April, May and June birthstone guide as well.
July Birthstone: Ruby
The Gemstone That Burns Like Love
Ruby is widely considered one of the most precious coloured gemstones in the world. Its English name comes from the Latin word “Rubeus”, meaning red, and that red is no ordinary red. It is the red of deep feeling, of passion that doesn’t waver, of the kind of love people write poetry about.
Ancient Indians called ruby the “King of Gems” and believed it protected its wearer from danger. Burmese warriors reportedly embedded rubies beneath their skin before battle, trusting the stone to make them invincible. Whilst modern wearers have no need for such rituals, the sense of courage and vital energy that ruby carries still comes through in every piece of jewellery it graces.
Ruby’s Qualities and What to Look For
Ruby belongs to the corundum family, the same mineral species as sapphire. The difference is chromium, which creates that signature red. Colour is the most important quality factor: the finest rubies display what the trade calls “Pigeon Blood Red”, a pure, saturated, slightly fluorescent deep red that commands extraordinary prices.
With a Mohs hardness of 9, ruby is second only to diamond in durability, making it an excellent choice for everyday wear.
What July’s ruby symbolises:
- Protection of health and vitality
- Passion, courage and the fire of love
- Confidence and the drive to succeed
How to Style Ruby Jewellery
Ruby’s warmth glows beautifully against 18K rose gold or yellow gold settings. As a solitaire centre stone it makes a bold birthday gift; surrounded by micro-pave diamonds it becomes something altogether more refined. If you’re creating a love token, consider pairing a ruby centre stone with a personalised ring engraving inside the band, a secret only the two of you will know.
August Birthstone: Peridot
Summer Sunlight Crystallised in Green
Peridot occupies a colour entirely its own in the gemstone world: a luminous, yellowish green that seems to hold afternoon sunlight within it. Hold a fine peridot in your palm on a sunny day and it feels almost warm to the touch.
Ancient Egyptians called it the “gem of the sun” and believed it was formed from solar fire. Legend even credits Cleopatra’s famous emerald collection as possibly being peridot, a case of mistaken identity that speaks volumes about how captivating the stone is. Peridot is also one of the very few gemstones found in meteorites, making it quite literally out of this world.
Peridot’s Qualities and What to Look For
Peridot has a Mohs hardness of approximately 6.5 to 7, somewhat softer than ruby or sapphire, so it benefits from a protective setting, particularly for rings worn daily. The most prized colour is a rich, golden green with strong saturation; the deeper and more vivid the green, the more valuable the stone.
What August’s peridot symbolises:
- Light and the dispelling of negative energy
- Harmony in the home and in relationships
- Inner calm and quiet self-assurance
How to Style Peridot Jewellery
Peridot’s cheerful yellow-green works beautifully against white gold for a clean contemporary feel, or yellow gold for something warmer and more classic. It translates especially well into pendants and earrings, where the stone can catch the light close to the face. It also works wonderfully as a shared motif in couple rings, where two matching peridots represent two people choosing the same path.
September Birthstone: Sapphire
Still Waters, Deep Blue, and a Promise That Lasts
When most people picture a sapphire, they see a rich, velvety blue, and they may also picture the most famous sapphire ring in modern history: the one Prince Charles gave to Diana Spencer, which Prince William later placed on Catherine Middleton’s finger. Sapphire has been a royal favourite for centuries, and it is not hard to understand why.
That blue carries a particular quality: it is the colour of clarity, of calm certainty, of a commitment you make without reservation. In the Middle Ages, clergy wore sapphires as a symbol of heaven. Lovers exchanged them as a pledge of fidelity. Today, couples in Singapore and across the world still choose sapphire when they want a stone that says something beyond what words can manage.
Sapphire’s Qualities and What to Look For
Like ruby, sapphire is a variety of corundum, distinguished by trace elements of titanium and iron that produce its blue. With a Mohs hardness of 9, sapphire is superbly durable and perfectly suited to rings worn every day.
The finest sapphires come from Sri Lanka, Myanmar and Kashmir. Among colour grades, “Royal Blue”, a deep, rich blue with a hint of violet, is the most sought after. When assessing quality, apply the same logic you would use for diamonds: colour saturation, clarity and cut all matter. The 4Cs engagement ring guide offers a useful framework for thinking about gemstone quality more broadly.
What September’s sapphire symbolises:
- Wisdom and clear-sighted judgement
- Loyalty, sincerity and enduring commitment
- Serenity and mental clarity
How to Style Sapphire Jewellery
Sapphire paired with platinum or white gold is quiet elegance at its finest. As a coloured centre stone in a bespoke ring, or as an accent stone in a wedding band, it carries a timeless romance that trends can’t touch. For a partner born in September, a sapphire engagement ring carries a double meaning that makes the moment even more layered.
Birthstone Jewellery in Practice: 3 Meaningful Occasions
Occasion One: Birthday Gifts, the “Made for You” Kind
Most gifts are chosen and forgotten. A piece of jewellery set with the recipient’s birthstone says something different: this was made with you specifically in mind. A ring, a necklace pendant, a pair of earrings, all are excellent options. For something even more personalised, consider adding the recipient’s birthdate as an engraving inside the band, completing the story.
Occasion Two: Engagement Rings with a Personal Layer of Meaning
The classic engagement ring features a diamond, but an increasing number of couples are choosing to incorporate birthstones, adding a layer of personal significance that a standard solitaire simply cannot offer. A July bride might adore a ruby-centred ring; a September groom might fall for a sapphire band he’ll never want to take off. The 7-step guide to choosing the right engagement ring walks you through the full process if you’re not sure where to start.
Occasion Three: Anniversary Gifts That Carry the Weight of Time
Each year you’ve spent together deserves to be acknowledged properly. Anniversary gifts become particularly meaningful when they incorporate birthstones: imagine a ring set with both partners’ stones side by side, a quiet record of two lives becoming one.
4 Things to Consider When Choosing Birthstone Jewellery
1. Match the Gemstone’s Hardness to the Setting Style
Different hardness levels call for different settings. Ruby and sapphire, both at Mohs 9, are suited to virtually any setting style, from claw to bezel. Peridot, softer at 6.5 to 7, benefits from a more protective bezel or channel setting, particularly for rings worn daily.
2. Ask About Enhancement Treatments
Most coloured gemstones on the market have been heat-treated to improve colour, a widely accepted practice within the trade. Always ask your jeweller to be transparent about any treatments before you purchase. Understanding what you’re buying is a mark of informed confidence, much as knowing diamond types helps you shop for a diamond more wisely.
3. Choose the Right Metal to Complement the Stone
The metal you choose will define how the stone reads. Ruby sings against rose gold. Peridot looks freshest in yellow gold. Sapphire reaches its full depth in white gold or platinum. If you’re new to metal types, the K gold explained guide is a helpful starting point.
4. Care for Your Birthstone Jewellery Properly
Coloured gemstones, like diamonds, need regular cleaning to stay brilliant. The principles in our diamond cleaning guide apply broadly to most precious stones. A little routine care protects both the stone and the sentiment it carries.
A Birthstone Ring Is More Than a Piece of Jewellery
There is something quietly powerful about giving a birthstone piece. It signals that you paid attention, that you know who this person is and what month brought them into the world. For a July recipient, a ruby reflects their fire. For an August friend, a peridot mirrors their warmth. For a September partner, a sapphire honours their depth.
These are not just gemstones. They are the months, crystallised into something you can hold.

Editor’s Note
Every time I write about birthstones, I find myself checking the calendar, matching months to people I love. There’s something quietly moving about the idea that the month you arrived in the world comes with its own stone, its own energy, its own small promise of protection. Whether or not you believe in the metaphysics, the practice of giving a birthstone piece is one of the most thoughtful gestures in jewellery. It tells someone: I know when you were born, and I wanted to mark it with something lasting.
