Birthstone charms are small jewellery pieces that carry the gemstone, or the gemstone colour, linked to a particular birth month. Every month has at least one stone and three months have three. January is deep garnet red, April is clear white diamond, September is royal blue sapphire, and December runs from sky-blue turquoise to violet tanzanite. Below you will find all twelve months in order, the colour of each stone, the meaning that has traditionally been attached to it, and a note on how that colour behaves once it is sitting on a bracelet.
A quick word on meanings before the list. The qualities linked to each stone are folklore rather than fact, built up over centuries of trade, religion and gift-giving. They are worth knowing because they make a charm a more considered gift, not because the mineral does anything. Pick the stone that means something to the person wearing it.
Birthstone by Month: The Complete List
The birthstone by month system assigns one or more gemstones to each of the twelve calendar months. The version most jewellers work from today was standardised by the American jewellery trade in 1912 and extended three times since, which is why some months carry a single stone and others carry three.
January Birthstone: Garnet
Colour: deep wine red, though garnet also occurs in orange, green and near-colourless varieties.
Garnet is traditionally tied to protection, constancy and safe return. Medieval travellers were said to carry it on long journeys, and it was exchanged between friends as a token that they would meet again. Its darker, browner red sits warmly against gold plating.
February Birthstone: Amethyst
Colour: purple, running from pale lilac to deep violet.
The name comes from the Greek amethystos, meaning not intoxicated, and the Greeks linked the stone to clear thinking and self-control. It later became associated with calm and composure. Violet reads cleanly against silver and is one of the easiest colours to pair with the rest of a bracelet.
March Birthstone: Aquamarine
Colour: pale sea blue to soft blue-green. Bloodstone, the older March stone, is an opaque dark green flecked with red.
Aquamarine takes its name from the Latin for sea water and was traditionally carried by sailors as a charm for calm crossings. The meaning attached to it is courage and steadiness under pressure. Its pale blue is the softest on the list and works well in spring and summer stacks.
April Birthstone: Diamond
Colour: colourless and bright white, with rarer yellow, brown and pink varieties.
Diamond stands for strength and enduring attachment, a meaning helped along by the fact that it is the hardest natural material known, at 10 on the Mohs scale. A clear white stone is the most flexible charm on this list because it sits comfortably next to every other colour.
May Birthstone: Emerald
Colour: rich grass green, often with visible internal markings that gemmologists call the jardin.
Emerald has long been read as a stone of renewal and growth, associated in the ancient world with spring and with the goddess Venus. Deep green is a strong colour that holds its own beside gold and is best given a little space on a bracelet rather than crowded.
June Birthstone: Pearl, Moonstone, Alexandrite
Colour: cream and white for pearl, milky blue-white sheen for moonstone, and a colour shift from green in daylight to red under lamplight for alexandrite.
June carries three stones, more than any other month bar August and December. The shared meaning is purity, intuition and new beginnings. Pearl and moonstone are soft and porous compared with faceted gems, so if you want June in something worn daily, a stone-set charm in a pearl-white finish is the more practical route.
July Birthstone: Ruby
Colour: vivid crimson, a brighter and purer red than garnet's darker wine tone.
Ruby is linked to passion, vitality and courage. Sanskrit texts called it ratnaraj, the king of gems, and it was worn as a mark of standing. At 9 on the Mohs scale it is one of the more durable stones on the list, which is why red is such a common everyday charm colour.
August Birthstone: Peridot, Spinel, Sardonyx
Colour: olive to lime green for peridot, red through pink and blue for spinel, and banded brown and white for sardonyx.
Peridot is associated with light, warmth and good fortune, and it is one of the few gems that forms deep in the earth rather than in the crust. Fragments have also been identified in meteorite material. Spinel is the newest stone on the modern list, added in 2016.
September Birthstone: Sapphire
Colour: deep cornflower to royal blue, with pink, yellow and green fancy sapphires also occurring.
Sapphire stands for wisdom, loyalty and truth, and it was worn by clergy in medieval Europe as a symbol of heaven. A strong blue is one of the most wearable charm colours because it reads as neutral against both gold and silver.
October Birthstone: Opal and Tourmaline
Colour: shifting play-of-colour across pink, green and blue for opal, and a wide range for tourmaline, with pink as the birthstone variety.
Both stones are linked to hope, creativity and imagination. October is the most visually varied month on the list, which makes it easy to match to an existing bracelet: an iridescent charm picks up whatever colours are already there.
November Birthstone: Topaz and Citrine
Colour: golden yellow to warm amber, with topaz also found in blue and pink.
The meaning traditionally attached to November's stones is warmth, abundance and generosity. Citrine joined the list in 1952 as a more accessible alternative to topaz. Amber tones are the natural partner for gold plating and sit well in autumn and winter stacks.
December Birthstone: Turquoise, Tanzanite, Zircon
Colour: sky blue and blue-green for turquoise, violet-blue for tanzanite, and blue through colourless for zircon and blue topaz.
December's stones are read as protection, friendship and good fortune. Turquoise is among the oldest materials used in jewellery anywhere in the world. Tanzanite is the newcomer, added in 2002, and is found in commercial quantities in only one area of northern Tanzania.
Birthstone Colours by Shade Family
Birthstone colours fall into five broad families, and grouping them this way is more useful than reading down the calendar when you are matching a charm to a metal tone or building something that holds together visually.
- Reds and wines: garnet (January) and ruby (July). Garnet is darker and browner, ruby is brighter and purer.
- Blues: aquamarine (March), sapphire (September), and turquoise, tanzanite, zircon and blue topaz (December). The widest family on the list, running from pale to near-navy.
- Greens: emerald (May), peridot (August), bloodstone as the traditional March stone, and alexandrite in daylight (June).
- Purples and pinks: amethyst (February), pink tourmaline (October) and pink spinel (August).
- Neutrals and iridescents: diamond (April), pearl and moonstone (June), opal (October) and sardonyx (August).
As a rule of thumb, warm stones such as garnet, ruby, citrine and peridot sit better against gold charms, while cool stones such as aquamarine, sapphire, amethyst and clear white read cleaner on silver charms. Rose gold charms suit pink and peach tones. If you are combining three or four birthstones from the same family, break them up with a plain link or a neutral stone so the shades do not blur into one another.
Colour is also the practical way in for anyone whose month has a stone they simply do not like. Nothing obliges you to wear your own month, and picking by shade rather than by calendar is how most people end up with a bracelet they actually wear.
Where Birthstone Meaning Comes From
Birthstone meaning is a cultural inheritance rather than a fixed system, assembled over centuries from religious texts, regional trade custom and Victorian gift-giving, and only tidied into a single agreed list in the twentieth century. Knowing the lineage makes it easier to understand why charts disagree with each other.
Most historians trace the idea to the breastplate of Aaron described in Exodus, which was set with twelve stones representing the twelve tribes of Israel. The link between those twelve stones and the twelve months of the year was drawn much later. The traditional list familiar in the West is generally credited to Poland between the sixteenth and eighteenth centuries. In 1870 Tiffany and Co. published a verse pairing each month with a stone, which did a great deal to popularise the idea among Victorian buyers.
The modern list was standardised in August 1912, when the American National Retail Jewelers Association, now Jewelers of America, agreed a single roster at its convention in Kansas City. It has been revised three times: 1952 added alexandrite, citrine, tourmaline and zircon; 2002 added tanzanite to December; and 2016 added spinel to August. Britain has its own list, published by the National Association of Goldsmiths in 1937 and revised since, which is why a British chart and an American chart will not always agree.
The practical takeaway is that these lists were shaped by what jewellers could reliably stock and sell as much as by tradition. That is not a reason to dismiss them. It is a reason to treat the meanings as a shared story worth passing on rather than a rule you have to follow.
How to Build a Birthstone Bracelet
A birthstone bracelet is a bracelet built around one or more birth-month stones, usually alongside charms that mark names, dates or shared memories. Because charm links are added one at a time, it is a piece you can start small and extend over years, which is what makes it work as a family or anniversary gift.
Three arrangements cover most of what people actually build:
- One stone as an anchor. Your own month at the centre of the bracelet, with everyday charms either side. The simplest version and the easiest to add to later.
- One charm per person. A family bracelet with a stone for each child, parent or sibling, arranged either in birth order or by shade so the colours run smoothly from one end to the other.
- A matched pair. Two stones side by side for a couple, a friendship or a parent and child, often with a shared symbol charm between them.
A few things worth getting right. Cluster the coloured stones towards the centre rather than scattering them, and use plain gold or silver links at the edges so the colours are not competing for attention. Keep to two metal tones at most. If three of your stones sit in the same family, three blues for a March, September and December set, space them with a neutral white or a plain link so each one still registers. And leave room: most people underestimate how many charms they will want to add in the first year.
If you are starting from scratch, you can build your own birthstone bracelet link by link and match the exact shade you want, rather than accepting whatever a pre-made piece happens to include. Browse the finished charm bracelets if you would rather start from a base, or the ready-made charm sets if you are buying as a gift and want it to arrive complete.
Choosing Birthstone Charms That Last
Charms worn daily need materials that survive water, sweat and friction, so the practical specification matters as much as the stone you choose. This is where a lot of birthstone jewellery disappoints, because the stone is chosen for meaning and the setting is chosen for price.
Hardness is the first filter. Diamond sits at 10 on the Mohs scale, ruby and sapphire at 9, topaz at 8, and the quartz stones including amethyst and citrine at 7. All of those cope with daily wear. Pearl, opal, moonstone and turquoise are softer and more porous, so a June, October or December piece in a genuine stone wants gentler treatment, or a stone-set charm in the right shade if it is going on every day.
Care is straightforward. Put jewellery on after perfume and moisturiser rather than before, dry charms properly after swimming or showering, and store them so they are not knocking against harder pieces. Softer stones want a separate pouch. Done consistently, that is the difference between a bracelet that lasts a season and one that gets handed on.
Whichever month you are buying for, the stone is the starting point rather than the whole decision. Get the colour right for the person, get the materials right for how they live, and the meaning takes care of itself.
