Pukhraj: How Many Ratti Should You Wear?

⚡ Quick Answer — Nidhi Shrimali

Most astrologers suggest a pukhraj (yellow sapphire) of at least 3 ratti for an adult, and many settle on 5 to 7.5 ratti. One ratti is roughly 0.91 carat in the common Indian market convention, so 7 ratti is about 6.4 carats. The right weight depends on your chart and budget. Clarity and treatment matter more than an extra ratti, and the stone should be worn only after Jupiter is checked in your kundli.

What a Ratti Actually Is

The ratti is an old Indian unit of weight. It comes from the gunja seed (Abrus precatorius), the small red seed with a black spot that goldsmiths once used as a counterweight. Gunja seeds are fairly uniform in weight, which is why they became a standard long before anyone had a digital scale.

Today no jeweller weighs a stone against seeds. Every gemstone is weighed in carats on an electronic scale, and the ratti is worked out from that figure. So when someone asks "pukhraj kaise ratti milta hai", the honest answer is: the stone is weighed in carats, and the seller converts the carat weight into ratti using a fixed ratio.

The catch is that not every seller uses the same ratio. That is the first thing to understand before you compare a "7 ratti" stone at one shop with a "7 ratti" stone at another.

Ratti, Carat and Gram: The Conversion

The convention you will meet most often in Indian gem markets treats one ratti as about 0.91 carat. One carat is fixed internationally at 200 milligrams, so one ratti on this convention is roughly 0.18 gram. Some sellers use a different ratio, and older texts describe a lighter ratti, so always ask which conversion a shop is using. The carat weight on the lab certificate is the figure you can rely on.

Here is how common pukhraj weights work out on the 0.91 convention. These are approximate and rounded.

Notice how small the gram figures are. The gap between 5 and 7 ratti is well under half a gram. That is why a stone's quality, not one more ratti, decides most of what you are paying for.

How Many Ratti of Pukhraj Should You Wear?

There is no single number written in the classical texts that every astrologer follows. The texts on gems describe which stone belongs to which planet and what makes a stone flawed. The ratti counts you hear today come mostly from family and market practice.

In practice, I look at three things:

• How Jupiter sits in the chart. If Jupiter is a helpful planet for your lagna but weak by sign or house, a pukhraj may be suggested. The weaker the planet, the more some astrologers lean towards a slightly larger stone. If Jupiter is not helpful for your lagna, no weight is right.
• The quality you can afford. A clean, well-coloured 5 ratti stone is a better choice than a cloudy, cracked 8 ratti one. I would rather a client wear a smaller good stone than a bigger poor one.
• The hand and the ring. A 9 ratti pukhraj on a slim index finger can be awkward to wear every day. A stone you take off because it catches on things is doing nothing.

For most adults, 5 to 7.5 ratti is where the advice lands. If you were told a weight without anyone looking at your chart, ask why that weight. A good astrologer can explain it.

The Body-Weight Rule

You will often hear that you should wear one ratti for every ten kilograms of body weight, so a 60 kg person wears 6 ratti and an 80 kg person wears 8. It is easy to remember, which is why it spreads.

I do not know of any classical text that gives this rule, and it can mislead. It tells a heavier person with a well-placed Jupiter to buy an expensive large stone they may not need, and it tells nobody whether they should wear pukhraj at all. Treat it as a rough starting point at most, never as the reason to buy.

Is There a Minimum Weight?

Most astrologers will not suggest a pukhraj under about 3 ratti for an adult. The common view is that a very small stone is too slight to serve as a remedy. Many prefer 5 ratti or more where the budget allows.

For children the advice is different. I do not suggest gemstones for young children at all; the chart is still young, the habits of wearing a ring are unreliable, and other remedies are gentler. For a teenager, if a stone is suggested after a reading, a smaller weight is usual.

The 6, 11 and 15 Ratti Belief

Many families in North India avoid gemstones of exactly 6, 11 or 15 ratti. This is why you see sellers offering "sava chhah" (6.25) or a weight just above or below.

I cannot point you to a classical text that lays this down. It is a widely held custom, and if your family follows it, there is no harm in respecting it, because the difference between 6 and 6.25 ratti costs little. If your family does not follow it, there is no need to worry about a 6 ratti stone you already own.

5, 6, 7 or 7.5 Ratti: Choosing Between Them

These are the weights people search for most, so here is how I think about them.

• 5 ratti (about 4.55 ct). A sensible first pukhraj. It sits well in most rings, and you can afford better clarity at this size.
• 6 ratti (about 5.46 ct). Fine in itself. If your family avoids 6, choose 6.25.
• 7 ratti (about 6.37 ct). Common for men and for people whose chart calls for a firmer Jupiter remedy. Price per carat usually climbs here.
• 7.5 ratti (about 6.83 ct). Clearly larger to the eye. Worth it only if the quality holds up at this size.

If the choice is between a better 5 ratti stone and a weaker 7 ratti one at the same price, I suggest the 5. You can compare stones of different weights in our gemstone collection and ask about the certificate of any one before you decide.

What Decides the Price of a 5, 6 or 7 Ratti Pukhraj

People search for "pukhraj price 7 ratti" expecting one figure. There isn't one. Two 7 ratti yellow sapphires can differ in price many times over, and the weight is the least of the reasons. I do not quote prices in articles because they change with the market; a live listing is the only honest number.

Here is what moves the price:

• Price is per carat, and it rises with size. A 7 ratti stone usually costs more than 7/5 of a similar 5 ratti stone, because large clean crystals are rarer.
• Colour. A clear, even, medium yellow is valued most. Very pale stones and brownish ones cost less.
• Clarity. Inclusions visible to the eye, cracks and cloudiness all reduce value. Traditional texts also count some flaws as reasons not to wear a stone at all.
• Treatment. Unheated stones cost much more than heated ones of the same look.
• Origin. Sri Lankan (Ceylon) stones usually carry a premium.
• Cut. A well-cut stone shows more colour and life. A deep, heavy cut can add weight without adding beauty.

A very cheap "7 ratti natural pukhraj" is a warning sign. It is more likely to be treated heavily, a different mineral, or synthetic.

Ceylon, Bangkok and Other Origins

"Ceylon pukhraj" means a yellow sapphire mined in Sri Lanka. These stones are known for a lighter, bright yellow and are the ones most often recommended in Indian practice. "Bangkok pukhraj" usually refers to stones traded through Thailand, which can come from several countries, and these are often deeper or more golden. Stones from Australia and parts of Africa are also sold.

From a jyotish point of view, origin does not change which planet the stone belongs to. A clean natural yellow sapphire from any source is pukhraj. Origin matters mainly for price and appearance, and it should be stated on the certificate if the lab has assessed it.

Heated, Unheated and Glass-Filled Stones

Many sapphires on the market are heated to improve colour and clarity. Heating is a long-standing trade practice and the result is still natural sapphire. It should be disclosed, and it lowers the price compared with an unheated stone.

Some astrologers insist on unheated stones for remedial use; others accept heated ones. I prefer unheated where the budget allows, but I would not tell anyone that a disclosed, heated, natural sapphire is useless.

Lead-glass filling and beryllium diffusion are different. They change the stone far more and are much less durable. A glass-filled stone is not what a jyotish remedy calls for, and many traditional sellers would not offer it as pukhraj.

Yellow Topaz, Citrine and Synthetic Sapphire

Pukhraj is yellow sapphire, a variety of the mineral corundum. Confusion comes from the English word "topaz", which is a different mineral. Yellow topaz and citrine (sometimes sold as sunehla) look similar and cost much less. They are sold openly as substitutes (upratna) for Jupiter, and that is fine if you know what you are buying. The problem is when they are sold as pukhraj.

Lab-grown sapphire is real corundum made in a factory. It can be hard to tell from natural stone without testing. A gem lab can tell the difference; your eye usually cannot.

What the Lab Certificate Should Say

A certificate from a recognised gem lab is the only reliable check most buyers have. Before you pay, read it for these points:

• Identification: natural corundum, yellow sapphire. Not "yellow stone" or "topaz".
• Weight in carats, so you can check the ratti conversion yourself.
• Treatment: whether heat or any other treatment was found.
• Measurements and a photo that match the stone you are buying.
• A report number you can verify with the lab where it offers online lookup.

Who Should Wear Pukhraj, and Who Should Not

Pukhraj belongs to Jupiter (Guru). It is traditionally suggested where Jupiter rules good houses for your lagna and is weak or troubled in the chart, often for questions of children, education, marriage for women, teaching, law and counselling.

It is usually not suggested when Jupiter rules difficult houses for your lagna. Many astrologers are cautious with pukhraj for Taurus, Libra, Capricorn and Aquarius ascendants, though placement and dasha can change the answer. Pukhraj is also not normally combined with diamond or blue sapphire in the same ring or hand, because of the traditional relationships between the planets.

This is why a weight question cannot be answered on its own. The guide to choosing a gemstone from your kundli goes through the lagna logic in more detail, and the blue sapphire guide covers the stone people most often confuse it with. If you want to know whether Jupiter is a friend or a problem in your chart, a kundali analysis answers that before you spend anything.

Metal, Finger and Day

The usual practice for pukhraj:

• Metal: gold is traditional. Some wear it in panchdhatu or silver when gold is not practical.
• Finger: the index finger (tarjani) of the working hand, which is Jupiter's finger.
• Day and time: Thursday morning, preferably in the bright half of the lunar month (shukla paksha).
• Setting: an open back so the stone touches the skin, which most traditions prefer.
• Before wearing: wash the ring in raw milk or Ganga jal, light a lamp, and chant a Jupiter mantra such as "Om Brim Brihaspataye Namah" 108 times.

If the stone makes you uneasy after wearing it, take it off and have the chart rechecked. Do not keep wearing a stone out of fear of wasting the money.

What Pukhraj Cannot Do

A pukhraj is a traditional remedy for Jupiter. It does not guarantee marriage, children, a job or wealth. A heavier stone does not guarantee more of anything either.

Some sellers link pukhraj to cures for liver trouble, jaundice or infertility. Do not rely on that. For any health concern, see a doctor first; a gemstone can stay part of your faith alongside treatment, but it does not replace it. The same goes for money: no stone is a financial plan. Other gemstone posts on this blog, including gemstones for career, follow the same rule.

It is a custom rather than a rule from the classical texts. If your family follows it, choose 6.25; if not, a 6 ratti stone you already own need not worry you." }, { "question": "Is yellow topaz the same as pukhraj?", "answer": "No. Pukhraj is yellow sapphire, a variety of corundum. Yellow topaz and citrine are different minerals that look similar and cost much less. They are sold as substitutes (upratna) for Jupiter, which is fine if labelled honestly, but they are not pukhraj." }, { "question": "Can pukhraj cure illness or guarantee marriage?", "answer": "No. Pukhraj is a traditional remedy for Jupiter, not medicine and not a guarantee of marriage, children or wealth.
