Birthstone for Each Month: The Table

This is the modern list used by jewellers, with the additional stones that later revisions accepted.

Where the Birthstone List Comes From

The idea of twelve stones goes back to the breastplate of the high priest Aaron described in the Book of Exodus, set with twelve stones for the twelve tribes of Israel. Later writers, among them Josephus in the first century and St Jerome in the fifth, connected those twelve stones with the twelve months and the twelve signs of the zodiac.

For a long time the custom was to own all twelve and wear each in its month. Wearing only the stone of your own birth month is a much later habit, usually traced to Europe a few centuries ago.

The list you see today was fixed in 1912, when American jewellers agreed on a standard. The trade has revised it since: alexandrite, citrine and zircon were added in 1952, tanzanite in 2002 and spinel in 2016. So the modern birthstone chart is a trade standard built on an old religious symbol. It is not an astrological calculation.

January, February and March

• January: garnet. Usually a deep wine red, though garnet occurs in green and orange too. It is durable enough for daily wear.
• February: amethyst. Purple quartz. It is plentiful and affordable, and in India it is sometimes suggested as a mild substitute for blue sapphire.
• March: aquamarine. The pale blue variety of beryl, the same mineral family as emerald. Bloodstone, a dark green stone flecked with red, is the older March stone.

April, May and June

• April: diamond. The hardest gem. In Jyotish it belongs to Venus. See our diamond listing.
• May: emerald. Green beryl. It is beautiful but brittle, and almost all emeralds have natural inclusions. In Jyotish emerald (panna) is Mercury's stone.
• June: pearl. An organic gem made by a mollusc, soft and in need of gentle care. Alexandrite, which changes colour between daylight and lamp light, and moonstone are the alternatives. Pearl (moti) is the Moon's stone in Jyotish.

July, August and September

• July: ruby. Red corundum, second only to diamond in hardness among the common gems. In Jyotish ruby (manik) is the Sun's stone.
• August: peridot. A yellow-green gem. Spinel was added as a second choice, and sardonyx is the traditional one.
• September: sapphire. Corundum in every colour except red. When people say "sapphire" without a colour, they mean blue.

Blue Sapphire: Which Month's Birthstone?

Blue sapphire is the birthstone for September. Anyone born from 1 to 30 September has sapphire as their birthstone on the modern list, and blue is its classic colour.

The answer changes completely in Vedic astrology. There, blue sapphire (neelam) belongs to Saturn. It is the stone for the Moon signs and ascendants Saturn rules, Capricorn (Makar) and Aquarius (Kumbh), and it is prescribed only when Saturn is a helpful planet in the chart. Being born in September has nothing to do with it.

Neelam is also the stone Indian astrologers are most careful about. It is traditionally tried for a few days before being worn for good. If you are September-born and want a blue sapphire ring as a birthstone, read the blue sapphire guide first, and see how the blue sapphire we list is described.

October, November and December

• October: opal. Known for its shifting play of colour. It is soft and can crack if it dries out or is knocked. Tourmaline is the alternative. In India opal is often worn as a substitute for diamond, for Venus.
• November: topaz. Yellow to orange topaz is the traditional stone, with citrine as the affordable alternative. Topaz is often confused with yellow sapphire. They are different minerals, and the pukhraj guide explains how sellers blur the two.
• December: turquoise. An opaque blue-green stone, soft and porous. Zircon and tanzanite are the other December stones. Zircon is a natural gem and is not the same as synthetic cubic zirconia.

Why Some Months Have Two or Three Stones

There are three plain reasons.

• Cost and supply. Citrine was added beside topaz, and spinel beside peridot, so buyers had another option.
• Durability. Pearl and opal are soft. Alexandrite and tourmaline give June and October a harder choice.
• Old lists. "Traditional" stones such as bloodstone and sardonyx survive from earlier charts.

If your month has several, none is more "correct" than another. Choose the one you will actually wear.

Birthstone vs Rashi Ratna: The Vedic View

Jyotish has no stone for a calendar month. It works with nine gems, the navaratna, one for each graha, and it picks among them using the birth chart.

Three things differ from the Western list:

• The reference point. The stone is chosen from the ascendant (lagna) and the Moon sign (rashi), which depend on the date, the exact time and the place of birth. Two people born on the same day can need different stones.
• The zodiac. Vedic astrology uses the sidereal zodiac, so your Vedic sign is often not the sign a Western chart gives you. The Moon sign and Sun sign guide explains the gap.
• The purpose. A birthstone is a keepsake. A rashi ratna is worn to strengthen a planet, which is why choosing the wrong one is taken seriously.

You may see "Hindu birthstone by month" charts online. They are modern compilations. The classical method is by chart.

When Your Birthstone and Your Chart Disagree

They often will. Someone born in July has ruby as a birthstone. If that person's chart has the Sun ruling a difficult house, an astrologer would not suggest ruby at all.

How much this matters depends on the stone and how you wear it. Soft, mild stones such as garnet, amethyst, peridot and turquoise are not among the navaratna, and people wear them freely as jewellery. The stones that are also planetary gems, namely ruby, pearl, emerald, diamond and sapphire, are the ones tradition asks you to check. Of these, blue sapphire calls for the most care.

A practical middle path: wear a navaratna birthstone as an occasional pendant or earrings if you like it, and keep the daily, skin-touching ring for the stone your chart supports.

Which List Should You Follow?

• For a birthday gift or a piece of jewellery you simply like: the month list. It is a pleasant custom and nothing more is claimed for it.
• For an astrological purpose: the chart. The guide to choosing a gemstone walks through the method, and a kundali analysis gives a specific answer, including the answer "no stone needed".
• If you do not know your birth time: stay with the month list or with mild stones until the chart can be worked out.

Gifting a Birthstone

A birthstone makes a thoughtful gift because it is personal without needing a size. Pendants and earrings are safer than rings for that reason. For children, choose a hard, plain stone in a secure setting, and avoid pearl and opal, which scratch and crack.

If the person you are buying for follows Jyotish, ask before gifting a ruby, pearl, emerald, diamond or sapphire. Many families will not wear a planetary gem that was not chosen for them.

Buying Checks for Any Birthstone

• Ask whether the stone is natural, treated or lab-grown. All three are sold legitimately, but they must be named.
• For ruby, sapphire, emerald and diamond, ask for a report from a recognised gem lab.
• Check the carat weight on the report, not only the seller's label.
• Know the common mix-ups: citrine sold as topaz, topaz sold as yellow sapphire, glass sold as emerald, and cubic zirconia sold as zircon or diamond. The gemstone vs crystal explainer covers how these categories differ.

What a Birthstone Cannot Do

A birthstone is a symbol of the month you were born in. It does not bring guaranteed luck, money, love or health, and no gem treats an illness. A rashi ratna is a traditional astrological support, and it too comes with no guarantee. For medical, financial or legal problems, go to the qualified professional first.

[ { "question": "Which birthstone is for which month?", "answer": "January garnet, February amethyst, March aquamarine, April diamond, May emerald, June pearl, July ruby, August peridot, September sapphire, October opal, November topaz and December turquoise. Several months also have accepted alternatives, such as alexandrite for June and tanzanite for December." }, { "question": "Blue sapphire is the birthstone of which month?", "answer": "September. Sapphire is the modern birthstone for anyone born in September, and blue is its classic colour. In Vedic astrology, however, blue sapphire (neelam) is Saturn's gem and is chosen from the birth chart, not the birth month." }, { "question": "Who decided the birthstone list?", "answer": "The modern list was standardised by American jewellers in 1912 and has been revised since: alexandrite, citrine and zircon were added in 1952, tanzanite in 2002 and spinel in 2016. The idea of twelve stones is far older and goes back to the breastplate of Aaron in the Book of Exodus." }, { "question": "Is a birthstone the same as a rashi ratna?", "answer": "No. A birthstone follows the calendar month of birth and is a jewellery custom. A rashi ratna is chosen from the Moon sign and ascendant in the Vedic birth chart and is worn to strengthen a planet. The two often give different stones." }, { "question": "Can I wear my birthstone without checking my horoscope?", "answer": "Mild stones outside the navaratna, such as garnet, amethyst, peridot and turquoise, are worn freely as jewellery. Ruby, pearl, emerald, diamond and sapphire are also planetary gems, and tradition advises a chart check before wearing them daily. Blue sapphire needs the most care." }, { "question": "Why do some months have more than one birthstone?", "answer": "Alternatives were added for cost, supply and durability. Citrine sits beside topaz as an affordable option, and alexandrite and tourmaline give June and October a harder stone than pearl and opal. Older traditional stones such as bloodstone and sardonyx also remain on some lists." }, { "question": "Which gemstone suits my zodiac sign in Vedic astrology?", "answer": "By the ruling planet of the Moon sign: Aries and Scorpio red coral, Taurus and Libra diamond, Gemini and Virgo emerald, Cancer pearl, Leo ruby, Sagittarius and Pisces yellow sapphire, Capricorn and Aquarius blue sapphire. A full reading also checks the ascendant before a stone is advised." } ]
