LunaFebruary's main stone — the amethyst
Colour is the whole conversation with amethyst, and it does not simply run from pale to dark. The stones people keep coming back to sit in the middle of that range — a purple with a red flash inside it under warm light — while the very darkest material often goes inky and lifeless indoors, which is exactly where a ring spends its life. Tilt any candidate away from the shop lamps before deciding. If the purple dies in ordinary daylight, that is the version you will be wearing.
Until the nineteenth century this was a stone for crowns and cardinals, priced in the same bracket as emerald and ruby; bishops' rings still carry it out of that old habit. Enormous Brazilian and Uruguayan finds ended the scarcity inside a single generation, and amethyst became what it is today — a fine gem that almost anyone can own outright. Nothing about the mineral changed. The supply did, which is worth remembering whenever an assistant explains why some stone is precious.
So the question worth asking in a shop is not whether an amethyst is good, but which part of that range you are standing in. Small pale stones are nearly free and look it. The saturated middle is where the mineral becomes worth wearing. And the top of the market — deep Uruguayan or Zambian colour, large and clean — still lands under what a middling sapphire of the same size would cost. February is one of the few months on the chart where the best available version of the stone is within reach of an ordinary present.
What the amethyst actually is
Amethyst is quartz with a trace of iron in it, coloured over geological time by natural radiation in the ground: the same clear mineral as rock crystal, doped and irradiated. Most of it grows inside gas bubbles in ancient lava flows, and the mining is spectacular — in Rio Grande do Sul in Brazil and across the border at Artigas in Uruguay, miners open hollow geodes taller than a person, lined wall to wall with crystal points. Zambia sends the more saturated, slightly bluish material, Uruguay the densest purple, Brazil the bulk of everything else.
Two things are worth knowing before you buy. Synthetic amethyst has been grown in factories since the 1970s and sits so close to the natural stone that telling them apart is laboratory work; at February's prices most sellers have no motive to lie, but at the top of the range it is a fair question to ask. And heat changes it permanently: held at about 470 °C the purple turns yellow, which is where a large share of the citrine on the market comes from — legal, routine, and almost never printed on the ticket. Glass imitations are the easy ones to catch: bubbles inside, and a purple that is suspiciously even, where natural crystals nearly always show patchy zoning.
The February stone as a gift
Start by ignoring the card that comes with it. Calm, clarity, sobriety, protection — amethyst is sold with all four printed beside it, none of them survive checking, and the only real harm in repeating them is that somebody dealing with something medical hears permission to wait rather than to see a doctor. With that set aside, February is generous to a buyer: the stone is hard enough for a ring worn daily, it exists in every size a setting could want, and a genuinely beautiful example costs less than a mediocre sapphire — so the difference is best spent on cut and mounting.
A rough cluster or a sawn slice of geode counts too, and for someone who never wears jewellery it is usually the better present: it sits on a shelf and does exactly the same job. If a second tradition appeals more than the jewellers' one, the astrological route splits the month in two — Aquarius stones through 18 February, Pisces from the 19th — and the two lists disagree without either of them being wrong.
Where the month chart came from
Nothing in geology or astronomy ties a mineral to a page of the calendar. The chart everyone quotes was agreed by American jewellers in 1912, in Kansas City, so that shops across the country would sell one list rather than twelve. It has been edited since: alexandrite, citrine, tourmaline and zircon were added in 1952, and tanzanite joined December as late as 2002 — thirty-five years after the stone was first dug up in Tanzania.
So when two shops give you two different stones, neither of them is lying. British lists keep bloodstone for March where American ones print aquamarine. June carries pearl from the old custom and moonstone plus alexandrite from the newer one. Read any of these charts as a custom with a paper trail — a dated commercial agreement — and not as a fact about the person born that month.
Month or star sign: two different lists
The month stone and the zodiac stone belong to different traditions: one is a jewellers' chart, the other is astrology, where the stone is derived from the ruling planet and the element. Two signs fall inside February: Aquarius stones (through February 18) and Pisces stones (from February 19). We do not repeat the astrology here — that reading lives on the sign pages.

Frequently asked questions
What is the February birthstone?
In the jewellers' chart the February birthstone is the amethyst. There is no single canon — traditional and modern charts differ — so no choice from that set is wrong.
Is amethyst a precious or a semi-precious stone?
The split itself is a Victorian sales convention, not a fact about minerals: someone decided that diamond, ruby, sapphire and emerald were precious and everything else was not, and amethyst had been on the top list until the Brazilian deposits arrived. Gemmologists no longer use the terms. What actually decides value in a February stone is colour, clarity and cut, in that order.
What is ametrine, and does it count for February?
Ametrine is a single quartz crystal that grew half purple and half golden, with the boundary often running as a clean diagonal through the finished stone. Essentially all of it comes from one mine, Anahí in Bolivia. It appears on no birthstone chart at all, so nobody can tell you it is February's — but it is half amethyst by any measure, and if you like it, that is reason enough.
The month-by-month chart is a 20th-century jewellery custom, not science: no link between a mineral and a birth date has ever been demonstrated. Stones do not heal and do not steer events — health questions belong with a doctor, not with a pendant. The stone images on this page are generated illustrations, not photographs of particular specimens.
