Short answer: a good dur-e-najaf is natural colourless quartz (rock crystal) that is clear to the eye or shows only fine natural veils, is cut with crisp, even facets or a smooth dome, and is large enough to sit well in a ring, often somewhere around ten to twenty carats. It is normally untreated. The main risks are not poor quality but substitution: glass, cubic zirconia or synthetic quartz sold under the same name.
We have already covered how to tell real dur-e-najaf from glass and zircon and how it differs from moh-e-najaf. This guide assumes the stone is genuine and helps you choose a good one: what to look at, which questions to ask, and how to buy online in Pakistan with confidence. Dur-e-najaf has a special place in many Shia and Sufi households; we describe those customs as tradition, and for any religious question we suggest you ask a scholar you trust.
What you are buying
Dur-e-najaf, "the pearl of Najaf", is the name used in Pakistan, Iran and Iraq for clear rock crystal. Mineralogically it is quartz, the same mineral as amethyst and citrine, but without colour. It is 7 on the Mohs scale, which is hard enough for a daily ring, and it has no cleavage, so it rarely splits.
The name links the stone to Najaf in Iraq. In tradition, stones found near Najaf were especially valued. In the market, though, "dur-e-najaf" describes the material, not a proven source. Natural rock crystal is mined in many countries, including Pakistan's own northern areas, where fine clear quartz crystals are found; see gemstones of Gilgit-Baltistan. No lab can confirm that a particular piece of quartz came from Najaf.
The quick checklist
| Factor | What a good stone looks like | What to avoid |
|---|---|---|
| Colour | Water-clear, no tint, or a very faint natural tint you are told about | Grey, smoky or yellowish cast sold as top quality |
| Clarity | Eye-clean, or fine natural veils that do not cloud the stone | Large white cracks reaching the surface |
| Cut | Symmetrical facets or a smooth, even dome; good polish | Wavy facets, scratches, a lopsided dome |
| Size | Proportionate to the hand and the ring | A very large stone in a thin setting |
| Treatment | Untreated, stated by the seller | Coated or "aura" quartz sold as plain dur-e-najaf |
| Identity | Quartz, confirmed by seller or lab | Glass or cubic zirconia under the same name |
Colour: clear means clear
A fine dur-e-najaf has no colour at all. Look at it table-down on white paper in daylight. If the paper looks grey, brownish or yellow through the stone, there is a tint. Smoky quartz and very pale citrine are both quartz too, and a faint tint is not a fault in itself, but it should not be sold as top quality dur-e-najaf. If you like a grey-brown stone, look at smoky quartz instead, which is sold for what it is.
Avoid stones with a rainbow film on the surface. That is "aura" quartz, coated with a metal vapour, and it is not traditional dur-e-najaf.
Clarity: perfect is not always best
Clarity matters more for dur-e-najaf than for most stones, because there is no colour to distract the eye. There are two schools of thought among buyers.
- Eye-clean stones look like a drop of water and are the most sought-after for a formal ring.
- Stones with natural veils, wisps or tiny crystals are preferred by some buyers as visible proof that the stone is natural and not glass or a factory product. Fine inclusions do not weaken quartz.
What you should avoid is a crack that reaches the surface or a large white cloud in the centre. Surface-reaching cracks catch dirt, show up more after cleaning and can grow with a knock. An eye-clean stone that is very large and very cheap needs more questions, because synthetic quartz and glass are clean too.
Cut: faceted or cabochon
Dur-e-najaf is sold in two main styles.
Faceted
Faceted stones sparkle and catch light. Look along the facet edges with a loupe; they should be sharp and meet neatly at points. Symmetry matters: an oval should not be fatter on one side. A faceted stone with a shallow, wide back may look large from the top but has less sparkle, with a "window" in the middle where you can see straight through to the finger.
Cabochon (dome)
Smooth domed stones are the older, traditional style in many families and are often preferred for men's rings. The dome should be even, with no flat patches or ripples, and the polish should reflect a light bulb as a single clean image. A dome that is too low looks dull; a very high dome can catch on clothing.
Oval is the most popular shape in Pakistan for both styles. Rectangular cushions and octagons are also common for men's rings.
Size: carats, ratti and the ring
Quartz is a light stone, so dur-e-najaf is usually bought in larger weights than ruby or sapphire. Many men's rings use stones of roughly ten to twenty carats. Our dur-e-najaf collection lists each stone's exact weight, for example the 12.70-carat dur-e-najaf for a medium ring and the 17.25-carat dur-e-najaf for a bolder one.
If a seller quotes in ratti, ask which ratti. The gem ratti used in Pakistan is 0.91 carat; the jeweller's sunari ratti is about 0.61 carat. A "twenty ratti" stone could therefore be about 18.2 carats or about 12.2 carats. Use the carat to ratti converter before comparing two quotes.
Choose the size for the hand, not the number. Hold a coin of similar size against your finger; a stone wider than the finger looks heavy and knocks against things. For ring sizing, use the ring size guide.
Treatment: what is normal
Natural rock crystal is almost always sold untreated. It does not need heating to improve its colour, because it has none. The treatments to watch for are:
- Coating, which gives a rainbow or tinted film.
- Crackling and filling, rare in clear quartz, where cracks are deliberately created or filled for effect.
- Synthetic quartz, which is not a treatment but a lab-grown material; it is cheap to make and can be sold as natural.
Ask the seller in writing whether the stone is natural, untreated quartz. GemStore discloses known treatments on every listing, and our dur-e-najaf is natural.
What to ask the seller
- Is this natural quartz, or glass, cubic zirconia or synthetic quartz?
- Is it treated or coated in any way?
- What is the exact weight in carats, and the measurements in millimetres?
- Can you send a daylight photo and a short video, turning the stone?
- Where do you believe it was mined, and what is that based on?
- Is a certificate available, and can independent testing be arranged?
- What is the return policy if I am not satisfied?
A seller who answers all seven plainly is a good sign. Keep the answers in a WhatsApp chat or on the invoice, so you have them if you later have the stone tested. "Asli Najaf ka hai" with nothing behind it is not an answer to question five.
Choosing online in Pakistan
Buying a clear stone online is harder than buying a coloured one, because photos of colourless stones depend heavily on the background and light. A few habits help:
- Look for photos on a plain background. A dark background shows clarity; a white one shows any tint.
- Ask for a video. Clear stones show their facets and inclusions much better when they move.
- Compare carat weight with millimetres to check the stone is not unusually shallow or deep.
- Buy with cash on delivery where possible, so you can inspect the stone before paying.
- Use the return window to have the stone checked by a gemmologist if you wish.
For what to expect on price, see dur-e-najaf price in Pakistan and the monthly gemstone price guide.
Setting and wearing
Most dur-e-najaf in Pakistan is set in silver. A clear stone looks brightest in a setting with an open back, which lets light pass through. A closed back with a mirror-polished base is an older style that some families prefer. For a men's ring, choose a bezel or a strong four-claw setting; see chandi rings with stone and the stone setting service. Customs for which finger and hand to use are covered in how to wear dur-e-najaf.
Dur-e-najaf is also popular in tasbih strings and as a gift during Muharram and on religious occasions; see gemstone tasbih and Muharram and Islamic stones. Its place in Muslim tradition is described on our dur-e-najaf in tradition page.
