In Vedic astrology each of the nine planets (the navagraha) is paired with a gemstone. Together the nine are called the navaratna, and the tradition treats a stone as one optional remedy among several: it is said to carry something of its planet’s quality, and it is worn by people who, after a reading, wish to support that planet. It is never a requirement, and plenty of people live well without ever wearing one.
This section explains the nine stones, the classical background, and the usual method for narrowing the list by ascendant. It is written to help you ask better questions, not to sell anything. We sell nothing but the reading.
The nine ratnas and their planets
The table gives the pairings that are widely taught. Finger, metal and day vary by region, family and teacher, so treat the last three columns as common practice and not as a single rule.
| Planet | Stone | Hindi name | Finger often named | Metal often named | Day |
|---|---|---|---|---|---|
| Sun | Ruby | Manikya | Ring | Gold or copper | Sunday |
| Moon | Pearl | Moti | Little or ring | Silver | Monday |
| Mars | Red coral | Moonga | Ring | Gold or copper | Tuesday |
| Mercury | Emerald | Panna | Little | Gold | Wednesday |
| Jupiter | Yellow sapphire | Pukhraj | Index | Gold | Thursday |
| Venus | Diamond | Heera | Middle or ring | Silver, white gold or platinum | Friday |
| Saturn | Blue sapphire | Neelam | Middle | Silver or a mixed metal | Saturday |
| Rahu | Hessonite | Gomed | Middle | Silver or a mixed metal | Saturday in many traditions |
| Ketu | Cat’s eye | Lehsunia | Middle or ring | Silver or a mixed metal | Tuesday in many traditions |
Each stone will have its own page here: ruby, pearl, red coral, emerald, yellow sapphire, diamond, blue sapphire, hessonite and cat’s eye. Two practical guides sit beside them: substitute stones (the upratnas) and how to buy a gemstone.
The classical background, honestly stated
Gems have a long place in Indian texts. The Garuda Purana has a section on gems, and Varahamihira’s Brihat Samhita devotes chapters to gems and their examination, including how to judge quality. Those chapters are largely about the nature and grading of stones.
What they do not give, as far as we can say with confidence, is the modern rule of picking a stone by the lordship of the houses in a birth chart. That method, in which the stones of the lords of the 1st, 5th and 9th houses are considered and the stones of the lords of the 6th, 8th and 12th are usually avoided, is a later practice, taught widely by astrologers in recent centuries. It is a sensible piece of reasoning with a long following, and many astrologers use it, but it should not be presented as an ancient command. Schools and individual astrologers also disagree about details, and that is a good reason to treat any single list with some care.
How the ascendant method works
The idea is simple. Every ascendant gives each planet one or two house lordships. The 1st house is the self, and the 5th and 9th are the trine houses, which the tradition counts among the most supportive. So the stones of those three lords are the ones usually considered first. A planet that owns both an angle house and a trine house is called a yogakaraka, and its stone is added to the list. The lords of the 6th, 8th and 12th rule difficult houses, and astrologers usually avoid their stones, unless the planet also rules a good house, in which case it is called mixed and judged with more care. Rahu and Ketu rule no sign, so their stones are judged from their placement in the chart.
Reasoning like this is why the same planet’s stone can be advised for one ascendant and avoided for another. Ruby, for example, is the stone of the Sun, which is the lagna lord for Leo and a lord of a less welcome house for others. The twelve pages below set out the list for each ascendant, using the lordships exactly, along with the reasons.
Why the chart comes first
The list for an ascendant is a starting point and never the answer. A stone speaks for a planet, so the planet’s own condition in your chart matters more than the sign on your ascendant: the sign it occupies, the house it sits in, how close it is to the Sun, which planets aspect it, and which period of the Vimshottari dasha is running. A planet that is already strong may gain nothing from a stone. A planet in a difficult placement may be better supported by conduct, mantra and patience.
That is also why the remedies order on this site begins with behaviour, then mantra and giving, then temple visits, and only last a gemstone. If you do not yet know your ascendant, the free birth chart tool will find it, and the house lords guide shows where your lords sit. Nothing here replaces a conversation with a reader who can see the whole chart.

A note on health and promises
Gemstones are a devotional and astrological practice, and nothing on these pages is a medical claim. If you have a health concern, please see a doctor. No stone can promise a result, and any seller or adviser who guarantees one is promising more than the tradition does.
Frequently asked questions
↳ Which gemstone should I wear according to my ascendant?
The traditional starting point is the stone of your lagna lord, with those of the 5th and 9th lords and any yogakaraka also considered. Whether any of them suits you depends on how that planet stands in your own birth chart, so a reading should come first.
↳ Is it necessary to wear a gemstone in Vedic astrology?
No. A gemstone is one optional remedy, and most astrologers place behaviour, mantra and giving ahead of it. Many people never wear one.
↳ Are gemstones mentioned in the ancient texts?
Yes. The Garuda Purana and the Brihat Samhita both discuss gems at length, mainly their nature and quality. Choosing a stone by house lordship is a later practice that many astrologers follow, and it is not found in those chapters as a rule.
↳ Why do astrologers usually avoid some stones?
A gem is meant to strengthen its planet, so astrologers usually avoid the stones of planets that rule only difficult houses for your ascendant. This is a general tendency and not a prediction of harm, and an individual chart can change the judgement.
↳ Can I buy a gemstone from you?
We sell nothing but the reading, so the advice carries no interest in whether you buy a stone. If a stone suits your chart, the buying guide explains how to buy one with a laboratory certificate.
