Astrology Gemstones: Navaratna, Birthstones and Buying Tips
The nine Vedic gems, the Western birthstones, how astrologers choose a stone and how to buy one sensibly in the UK.
Astrology gemstones are stones worn to honour or strengthen a planet in your birth chart. Vedic astrology uses nine gems, the navaratna, one for each planet, while Western tradition gives a birthstone to each month. They are a cultural and spiritual tradition, not medicine, and no stone can guarantee any result.
What are the nine Vedic gemstones (navaratna)?
Navaratna is Sanskrit for “nine gems”. Vedic astrology, the tradition from India, works with nine planets called the navagraha: the Sun, the Moon, five visible planets, and the two lunar nodes, Rahu and Ketu. The nodes are points in the sky, not physical bodies, and you can read about them in our guide to Rahu and Ketu. Each of the nine is paired with one gemstone.
| Planet (Sanskrit name) | Gemstone | Common Hindi name | Lower-cost substitute often used |
|---|---|---|---|
| Sun (Surya) | Ruby | Manik | Red garnet or red spinel |
| Moon (Chandra) | Pearl | Moti | Moonstone |
| Mars (Mangal) | Red coral | Moonga | Carnelian |
| Mercury (Budh) | Emerald | Panna | Peridot or green tourmaline |
| Jupiter (Guru) | Yellow sapphire | Pukhraj | Citrine or yellow topaz |
| Venus (Shukra) | Diamond | Heera | White sapphire or white zircon |
| Saturn (Shani) | Blue sapphire | Neelam | Amethyst or iolite |
| Rahu (north node) | Hessonite garnet | Gomed | None in common use |
| Ketu (south node) | Cat’s eye chrysoberyl | Lehsunia | None in common use |
Some people wear all nine together in a single navaratna ring or pendant, which is treated as a general piece honouring every planet. More often an astrologer suggests one stone for one planet. For the meaning of each planet, see what each planet means in astrology.
What are the Western birthstones by month?
The Western system is simpler and has little to do with a birth chart. It gives a stone to each calendar month. The modern lists were drawn up by jewellery trade bodies during the twentieth century, and they have been revised since. That is why lists differ slightly from one jeweller to the next. The table shows the stones most widely used in the UK.
| Month | Main birthstone | Common alternative |
|---|---|---|
| January | Garnet | None in common use |
| February | Amethyst | None in common use |
| March | Aquamarine | Bloodstone |
| April | Diamond | Rock crystal |
| May | Emerald | Chrysoprase |
| June | Pearl | Moonstone |
| July | Ruby | Carnelian |
| August | Peridot | Sardonyx |
| September | Sapphire | Lapis lazuli |
| October | Opal | Tourmaline |
| November | Topaz | Citrine |
| December | Turquoise | Tanzanite |
A birthstone is a lovely basis for a gift. It is a calendar custom, though, not an astrological prescription.
How do astrologers choose a gemstone?
A careful Vedic astrologer never picks a stone from your sun sign or birth month alone. The choice comes from the whole birth chart, which needs your date, time and place of birth. In broad terms they look at:
- Your ascendant. This is your rising sign, called the lagna in Vedic astrology. It decides which planets are counted as helpful for you and which are not.
- The planet’s role and strength. The usual aim is to support a planet that is helpful for your chart but poorly placed. Stones are not normally suggested for planets that are already strong or that rule difficult houses.
- Your current planetary period. Vedic astrology divides life into periods called dashas, each ruled by a planet. A stone is often linked to the period you are in.
- Practical details. Tradition also sets out the metal, the finger and the weekday for first wearing the stone.
Remember that Vedic astrology uses the sidereal zodiac, so your signs may differ from the Western ones you know. Our guide to Vedic and Western astrology explains the difference. This is another reason a chart from a newspaper star sign cannot be used to choose a stone.
You may hear that the wrong stone, blue sapphire in particular, will bring disaster. This is scare-mongering. A gemstone is a piece of jewellery. If you do not enjoy wearing it, take it off. If a seller uses fear to push a purchase, walk away.
Gemstones are a tradition, not medicine: what are the free alternatives?
People wear planetary gems as an act of faith, a reminder of an intention or a link to family custom. Those are good reasons. There is no scientific evidence that gemstones treat, cure or prevent any illness or change events in your life. Never use a stone in place of seeing a GP, taking prescribed medicine or getting professional help.
The older texts do not treat gems as the only remedy, or even the main one. Classical remedies for a planet cost nothing:
- Mantra: repeating a short prayer or sound linked to the planet.
- Charity: giving time, food or money on the planet’s weekday.
- Conduct: living out the planet’s better qualities, such as keeping your word for Saturn or studying for Mercury.
- Fasting or simple observance on the planet’s day, if it suits you and your circumstances.
Our guide to simple astrological remedies covers these in detail. An astrologer who tells you that an expensive stone is your only option is selling, not advising.
How do you buy an astrological gemstone sensibly in the UK?
- Check the hallmark on the metal. In the UK, anything sold as gold, silver, platinum or palladium must carry a hallmark from one of the four assay offices in London, Birmingham, Sheffield and Edinburgh. The only exception is for very light items. Official hallmarking guidance sets the exemption weights at 1 gram for gold and palladium, 7.78 grams for silver and 0.5 grams for platinum.
- Know what a hallmark does not cover. It confirms the metal only. It says nothing about the stone.
- Ask about the stone in writing. Is it natural or made in a laboratory? Has it been heated, filled or dyed? Treatments are common and legal, but they affect the price and should be disclosed.
- For a costly stone, ask for an independent report. A report from a recognised gemmological laboratory is worth far more than a certificate printed by the seller.
- Set a budget first. Tradition does not say a dearer stone works better. A modest stone or a substitute is entirely acceptable.
- Keep the receipt and check the returns policy before you pay, especially when buying online or from abroad.
Frequently asked questions
Which gemstone should I wear for my star sign?
A gemstone should not be chosen from your star sign alone. Vedic astrologers work from the whole birth chart, including the rising sign, the strength of each planet and your current planetary period. If you simply like the idea of a birthstone, pick the one for your birth month.
Do astrological gemstones really work?
There is no scientific evidence that gemstones change health, luck or events. Their value is traditional, spiritual and personal. Many people find that wearing a stone helps them keep an intention in mind. Gemstones should never replace medical care, professional advice or practical action.
What is a navaratna ring?
A navaratna ring holds all nine Vedic gems together: ruby, pearl, red coral, emerald, yellow sapphire, diamond, blue sapphire, hessonite and cat’s eye. Each stone stands for one of the nine planets of Vedic astrology. It is worn as a general piece honouring all of them.
Does a hallmark prove a gemstone is genuine?
No. A UK hallmark confirms the precious metal content of the setting, such as gold or silver. It tells you nothing about the stone. For the gem itself, ask the seller to state in writing whether it is natural and whether it has been treated, and ask for an independent laboratory report.
The takeaway
Gemstones have a long and meaningful place in both Vedic and Western tradition. If you choose to wear one, base it on your full chart, buy it with the same care as any other jewellery, and treat it as a symbol of intention. The free remedies are just as respected.
