February Birthstone: The Complete Guide to Amethyst

If you were born in February, your birthstone is amethyst — the purple variety of quartz that has been worn by Greek philosophers, medieval bishops, and Russian empresses, and that today is one of the few genuinely affordable gemstones with a color no other stone can quite match. This guide covers what amethyst actually is, why it is purple, what it means, where it comes from, how to judge quality, what it costs, and how to buy and care for it.

What the February Birthstone Actually Is

One mineral, one very famous color.

Amethyst is quartz. Chemically it is silicon dioxide — the same mineral as clear rock crystal, smoky quartz, citrine, and rose quartz — arranged as a rigid three-dimensional network of silicon-oxygen tetrahedra. That structure is what gives quartz its hardness and its resistance to weathering, and it is why a stone this inexpensive is still tough enough to wear.

What separates amethyst from every other quartz is a trace of iron and a very long exposure to natural radiation deep in the earth. Nothing else about it is unusual. It grows in the same six-sided columnar crystals with pyramid terminations that clear quartz does, often lining the inside of volcanic cavities — and in Brazil, those cavities can be geodes large enough to walk into.

Because amethyst forms in such abundance, it is one of the rare cases where a beautiful, hard, well-saturated gemstone is available in large sizes at a price most people can actually pay. A ten-carat amethyst is an ordinary thing. A ten-carat sapphire of comparable quality is a headline.

Why Amethyst Is Purple

The color science most guides skip.

Amethyst's violet comes from iron, but not in the simple way most gemstone color works. Trivalent iron (Fe³⁺) substitutes for silicon in the crystal lattice. Natural irradiation in the ground then knocks an electron loose from that iron, creating what mineralogists call an [FeO₄]⁰ color center — a structural defect that absorbs light in a way that leaves violet behind.

Three practical consequences follow from that, and they matter when you shop:

• Color is rarely even. Amethyst almost always shows color zoning — angular bands of darker and lighter purple, with the most intense color usually at the crystal terminations. A cutter's real job is orienting the rough so the finished stone reads as one color. Evenness of color is a bigger quality signal than depth of color.
• Amethyst is dichroic. Natural stones show reddish violet and bluish violet depending on the viewing angle. That subtle two-tone shift is part of why amethyst looks alive under moving light.
• Strong light can fade it. Because the color depends on a radiation-induced defect rather than a stable chemical bond, prolonged exposure to intense light or heat can lighten an amethyst. Normal wear is fine; a decade on a sunny windowsill is not.

Two named color grades come up constantly in the trade. "Deep Siberian" is the historic top grade — roughly 75–80% purple with 15–20% blue and a red flash depending on the light source. "Rose de France" is the opposite end: a pale lavender-lilac that was once dismissed as low grade and is now genuinely fashionable. Neither is objectively better. Deep Siberian costs more; Rose de France flatters cooler skin tones and reads far more modern.

February Birthstone Meaning & Symbolism

Sobriety, clarity, and quiet authority.

The name says it. "Amethyst" comes from the Koine Greek amethystos — from a- ("not") and methysko ("to intoxicate") — literally "not drunken." Ancient Greeks wore amethyst and carved drinking vessels from it in the belief that it would keep them sober, and because of its wine-dark color they linked the stone to Bacchus, god of wine.

From that root, every later meaning grows:

• Clarity and self-control. The original association — staying clear-headed when everything around you is not. Amethyst was believed to keep warriors and merchants quick-witted in battle and in business.
• Calm and rest. Renaissance Europeans thought amethyst cooled lovers overrun by passion. The modern version of that idea is amethyst as a stone of composure and sleep.
• Spiritual authority. Purple has meant royalty and clergy for two thousand years, and amethyst was the accessible way to wear it. Bishops' rings were traditionally set with amethyst.
• Personal empowerment. For a February birthday, amethyst is most often given as a symbol of inner strength — the stone you wear when you want to feel steady.

A note on honesty, because the internet is full of the opposite: these are cultural and historical associations, not medical claims. Amethyst has been credited with curing insomnia, headaches, and intoxication for millennia, and none of that is scientifically demonstrated. Wear it because it is beautiful and because the meaning is a nice thing to carry — not instead of seeing a doctor.

Amethyst is also the traditional gift for the sixth wedding anniversary, which makes an amethyst ring or pendant do double duty for a February-born partner.

The History Behind the Stone

From Alexander the Great to Cartier.

Royals have admired amethyst's deep purple since at least the era of Alexander the Great. Ancient Egyptians cut it into amulets. Medieval European soldiers wore it as protection in battle. It appears throughout the crown jewels of Europe and Asia.

Two owners stand out. Catherine the Great — Empress Catherine II of Russia, 1729–1796 — had a real appetite for the stone and wore amethyst necklaces, earrings, and ornaments in quantity, at a time when Russia was the world's principal source. And in 1953, Wallis, Duchess of Windsor, wore a Cartier-designed amethyst bib necklace to a gala at Versailles: twenty-eight step-cut amethysts, one oval faceted amethyst, and a large heart-shaped amethyst at the front, set with turquoise cabochons and brilliant-cut diamonds on a rope-like gold chain. It is still one of the most photographed pieces of colored-stone jewelry ever made.

The reason amethyst reads as "royal" and yet costs so little is a single accident of geology. Until the 19th century, amethyst was as rare and as expensive as ruby or emerald. Then enormous deposits were found in Brazil, supply exploded, and the price collapsed. The stone did not change. Its availability did — which is why you can buy the gem of empresses for the price of a nice dinner. For the wider story of how supply reshaped gemstone value, see our guide to the history of gemstones.

Does February Have Two Birthstones?

A common question with a clear answer.

No. Unlike March, June, August, October, November, and December — each of which has more than one officially recognized stone — February has exactly one modern birthstone: amethyst. It is amethyst on the U.S. list adopted in 1912, on the U.K. list of 2013, and on the updated U.S. list of 2019. February is one of the most stable entries in the whole calendar.

The confusion comes from older lists. Historic 15th–20th century European tradition assigned February amethyst, hyacinth, and pearl. Those alternates dropped out of use more than a century ago and no current authority recognizes them. If someone tells you February has a second birthstone, they are quoting a list that predates the modern one.

If you want to see how February compares to the rest of the year, our birthstone chart by month lays out all twelve, and neighboring months are covered in the January garnet guide and the March aquamarine guide.

Amethyst, Aquarius & Pisces

Where the zodiac list and the calendar list disagree.

February spans two signs, and the traditional zodiac-stone list does not line up with the month list — which is the source of a lot of confusion.

In practice: if you are buying a gift by birth month, amethyst is correct for anyone born in February. If the person you are buying for is specifically into astrology and is an Aquarius, a garnet piece is the more traditional zodiac choice — see our garnet meaning guide. Pisces gets amethyst either way.

Where Amethyst Comes From

Five places worth knowing by name.

Russia dominated the amethyst trade until the 19th century. Today the important production is in South America and Africa.

• Brazil — still the major supplier, especially the southernmost state of Rio Grande do Sul. Brazilian rough tends toward lighter color than stone from elsewhere, and it forms in hollow, crystal-lined geodes that can be big enough to stand inside. A four-ton, 3.7-meter Brazilian-Uruguayan-style geode is on public display at the American Museum of Natural History.
• Uruguay — the Artigas region produces some of the most saturated, deeply colored amethyst in the world, typically in smaller sizes than Brazil.
• Bolivia — the Anahí mine, hidden in the Pantanal wetlands, has one of the best origin stories in gemology: discovered by a Spanish conquistador in the 1600s and given to him as a dowry when he married Anahí, a princess of the Ayoreo people, then forgotten for three centuries and rediscovered in the 1960s. It is the world's source of ametrine, the naturally bicolored amethyst-citrine crystal.
• Zambia — the Kariba mine is among the largest amethyst producers on earth, and its material is known for superb, richly saturated color.
• United States — the Four Peaks mine sits high in the Mazatzal Mountains about 46 miles (74 km) from Phoenix, Arizona. Remote, waterless, brutally hot, and rattlesnake-ridden — and the source of exceptional dark purple and purplish-red crystals with a genuine American provenance.

How Amethyst Quality & Value Work

What you are actually paying for.

Amethyst is priced almost entirely on color. Because the supply of clean, large rough is so good, clarity and size are far less of a lever than they are for most gems — a well-cut, eye-clean amethyst is the baseline expectation, not a premium.

The single most useful shopping habit: look at the stone face-up, in more than one light, and rotate it. Zoning and a pale "window" through the middle are the two flaws that dull an amethyst, and both hide well in a single product photo.

Natural vs Lab-Created Amethyst

Both are real amethyst. One is much easier to buy well.

Lab-created amethyst has been produced since the 1970s and has the same chemical and physical properties as mined material — the same hardness, the same refractive index, the same color mechanism. In many cases it is genuinely difficult to separate the two without laboratory testing.

The economics here are unusual. With most gemstones, lab-created material exists because the natural stone is expensive. Amethyst is already cheap, so the practical difference is smaller than people expect:

Our position, plainly: for a February birthstone piece meant to mean something, natural amethyst is worth the small premium — the zoning and the dichroism are the character. For matched side stones or a large statement cut where uniformity is the point, lab-created is the smarter buy. Both are honest as long as the seller labels them.

Heat Treatment, Citrine & Ametrine

The one treatment you should know about.

Heat treatment is the standard, accepted enhancement for amethyst. It is used to lighten stones that are too dark and to remove unwanted brownish inclusions. Note what it cannot do: heat cannot make pale amethyst darker. Anyone claiming otherwise is selling something else.

Heat treatment produces a permanent color change, but it has two side effects worth knowing:

• Slight brittleness. Intensely heated amethyst can be marginally more fragile, so pointed faceted corners and sharp edges need care during setting and wear.
• Loss of dichroism. Heat amethyst far enough and it turns yellow-orange or brown and resembles citrine — but the two-tone shift disappears, which is exactly how gemologists tell heated amethyst from genuine citrine. Most commercial citrine on the market began life as amethyst.

Heat one part of a crystal and not the other and you get ametrine: a single stone that is purple at one end and golden at the other. Nature does this on its own at the Anahí mine in Bolivia, which is why Bolivian ametrine commands a premium over the lab-partitioned version.

Choosing February Birthstone Jewelry

Where amethyst works best, and where it needs help.

At Mohs 7, amethyst is hard enough for daily wear but softer than sapphire, ruby, or diamond — and it will slowly show wear on an exposed table facet after years of use. That single fact should drive the design choice.

1. For an everyday ring, protect the stone. A bezel or half-bezel shields the girdle and edges; a low-profile setting keeps the stone out of the path of door frames and countertops. High solitaire prongs look beautiful and take the most abuse.
2. For maximum color, go larger and shallower. Amethyst's color reads best at size. A 7×5mm oval shows more purple than a 4mm round of the same material, and it costs very little more.
3. Match the metal to the tone. White metals — sterling silver and white gold — keep amethyst cool, violet, and modern. Yellow gold warms it toward wine and reads vintage. Rose gold pulls out the red secondary hue and is the most romantic of the three.
4. For earrings and pendants, relax. Earrings and necklaces take almost no impact, so this is where you can buy the biggest, most dramatic amethyst your budget allows without worrying about durability at all.
5. For an engagement ring, be deliberate. Amethyst engagement rings are beautiful and increasingly popular, but they need a protective setting and an owner who will take the ring off for heavy work — see our guide to engagement ring settings.

Amethyst also pairs unusually well with other stones. Purple sits opposite yellow-green on the color wheel, so amethyst with peridot or a warm gold setting is a naturally balanced combination, and amethyst with clear white stones is the classic high-contrast look.

What February Birthstone Jewelry Costs

Realistic numbers.

Amethyst is the value proposition of the birthstone calendar. Loose commercial-grade amethyst trades in single-digit dollars per carat; even fine, deeply saturated material rarely reaches the per-carat price of an average sapphire. That means the setting, the metal, and the workmanship — not the stone — drive what you pay for a finished piece.

• Sterling silver pieces are the entry point, and with a good natural stone they do not look like an entry point. See what 925 sterling silver actually is.
• Gold vermeil sits in the middle: a heavy gold layer over sterling, for the look of gold at a fraction of solid-gold cost. Compare in our vermeil vs plated vs filled guide.
• Solid gold is where the cost sits in the metal — worth it for a ring meant to be worn for decades. Our 10K vs 14K vs 18K guide explains the tradeoff.

Because the stone is affordable, February is one of the few months where buying a larger, better-colored gem is genuinely within reach. Spend the extra on color quality rather than on carat count alone.

How to Care for Amethyst

Four rules, and one thing never to do.

1. Clean it with mild soap and a soft brush. Warm water, a drop of dish soap, a soft toothbrush around the setting, rinse, pat dry. This is the safest method and it handles almost everything.
2. Ultrasonic cleaners are usually fine; steam cleaners are not. Amethyst tolerates ultrasonic cleaning, but steam cleaning is not recommended — and if a stone has been heat treated or has visible inclusions, skip the ultrasonic too and stay with soap and water.
3. Keep it out of strong light and heat. Some amethyst fades with prolonged exposure to intense light. Normal wear is not a problem; storing it in a sunny window or wearing it on the beach every day is.
4. Store it separately. At Mohs 7, amethyst will be scratched by ruby, sapphire, and diamond. A soft pouch or a lined compartment keeps harder stones from frosting the polish.

Over many years of daily wear, an amethyst may show enough surface wear to want repolishing — which is normal, inexpensive, and completely restores the stone. Full method in our guide to cleaning jewelry at home.
