Yellow Topaz Buying Guide: Choosing a Golden Topaz in Pakistan

Yellow topaz is one of the most misunderstood stones in Pakistani markets. The name is used for genuine golden topaz, for citrine, for heated smoky quartz and sometimes for yellow glass, and the Urdu word sunehla is applied to more than one of them. Many buyers also come to it as a more affordable alternative to Pukhraj (yellow sapphire), which adds a further layer of confusion.

This guide is for anyone buying a yellow topaz, especially online. It explains how to judge colour, clarity, cut and size, what origin and treatment mean, how to make sure you are getting topaz rather than quartz, and the questions to put to any seller before you pay.

First, be sure it is topaz

Topaz is a silicate mineral of its own, hard at 8 on the Mohs scale and noticeably heavy for its size. Citrine is quartz, at 7 on the Mohs scale and lighter. Both can be the same golden yellow, and the trade has blurred them for a long time: names such as "golden topaz", "Madeira topaz" and "Brazilian topaz" have often been used for citrine. In Pakistan the name sunehla is used for citrine by many dealers and for topaz by others.

None of this is a reason to avoid either stone. Citrine is a fine, affordable gem. It is simply a different stone and should be priced as one. Ask any seller to write the mineral name, topaz or quartz, on the invoice. Our comparison of yellow sapphire and citrine and our guide to November's topaz and citrine explain how the three yellow stones differ.

Quick ways to separate topaz from citrine

• Weight in the hand. Topaz has a specific gravity of about 3.5 against quartz's 2.65. Two stones of the same face size will feel different, and on a scale the topaz weighs more.
• Cleavage marks. Under a loupe, topaz may show small flat, rainbow-like cleavage cracks. Quartz does not cleave this way.
• Polish and sharp edges. Topaz takes a slick, very bright polish and keeps sharp facet edges for years.
• Refractive index. A gem lab or a jeweller with a refractometer separates them in seconds. This is the reliable test.

Colour: the main factor in value

Yellow topaz ranges from pale lemon through golden yellow to deep orange-gold. The trade name imperial topaz is used for the most prized tones: a rich golden orange, often with a pinkish or reddish flash. These command a clear premium over plain yellow.

When judging colour, look for:

• Saturation. A clear, definite golden colour is better than a washed-out pale yellow.
• Tone. Medium to medium-dark is usually most attractive. Very dark brownish stones look muddy indoors.
• Evenness. Colour zoning, darker and lighter patches, can be visible face-up. Some is normal; strong patches lower value.
• Brown modifier. Many yellow topazes carry a brownish tint. The less brown, the cleaner and more valuable the colour.

Look at the stone under ordinary room light and daylight, not only under a jeweller's bright lamp, which flatters golden colours.

Clarity

Topaz is normally clean to the eye. Buyers can, and should, expect a yellow topaz to look clear without a loupe. Small crystals, liquid inclusions or fine feathers under magnification are normal and acceptable. Visible cracks, especially ones that reach the surface, are a concern because of topaz's cleavage: a crack along the cleavage plane can grow with a knock. A stone with eye-visible inclusions should be priced well below a clean one of the same colour.

Cut

A good cut makes the colour glow evenly across the stone. A poor cut leaves a dull, see-through "window" in the centre or dark, lifeless areas. Check:

• Brilliance. Tilt the stone. It should flash brightly from most of the face.
• Window. If you can read print through the centre of the stone, it is cut too shallow.
• Symmetry. The outline should be even, with a straight, even girdle.
• Shape. Topaz crystals are long, so oval, pear and emerald cuts are common and often give the best colour for the weight.

Size

Yellow topaz is available in large sizes, and price rises steadily with weight rather than in big jumps. A stone of 5 to 10 carats is very wearable in a ring; larger stones suit pendants. If you are buying by ratti, remember the standard gemstone ratti in Pakistan is 0.91 carat, while the jeweller's sunari ratti is about 0.61 carat. Our carat to ratti converter helps you compare.

Origin

The best-known source of imperial topaz is the Ouro Preto area of Brazil. Golden and yellow topaz also comes from Sri Lanka, Africa and elsewhere. Pakistan has its own topaz story: Katlang, near Mardan, is known for pink to peach and orange-tinted topaz, and the northern areas produce colourless and pale topaz. Our planned guide to Katlang pink topaz and the wider gemstone mines of Pakistan page tell that story. For most yellow topaz, origin matters less than colour; it is worth asking about, but only a laboratory can state it with confidence.

Treatment: what to ask about

Several treatments affect yellow and golden topaz:

• Irradiation. Colourless topaz can be irradiated to yellow or brown. Some of these colours are unstable and fade in sunlight.
• Heating. Some golden-orange topaz is heated to turn pink. Heat is less often used to improve yellow.
• Coating. A thin surface film can add colour. Coatings scratch and wear off at facet edges over time.

Natural, untreated golden topaz with stable colour is worth more. Ask the seller to state any known treatment in writing. Some natural brown and sherry-coloured topaz can also fade in strong sunlight; our topaz care guide explains how to protect it.

Yellow topaz as an alternative to Pukhraj

In Vedic practice yellow topaz is often suggested as an uparatna, a substitute stone for yellow sapphire, the gem of Jupiter. This is a belief, not a promise, and astrologers differ on whether a substitute carries the same weight; settle that with your own astrologer. On the practical side, yellow topaz is softer than sapphire (8 against 9), lighter in price, and easier to find in large clean sizes. If you have been advised to wear Pukhraj specifically, our guide to Pukhraj benefits and the planned yellow sapphire buying guide may help you compare.

Red flags when buying

• A very large, perfectly clean, deep orange stone at a low price. Fine imperial colour is scarce. A bargain of this kind is more likely to be citrine, coated topaz or glass.
• Colour that sits only on the surface. Look along the facet edges with a loupe. Worn spots where the colour is thinner suggest a coating.
• Round bubbles or swirl lines. These point to glass, not topaz.
• A seller who will not name the mineral. "Yellow stone", "sunehla" or "golden" on an invoice protects the seller, not you.
• Weight quoted for a mounted stone. The setting adds weight you should not pay stone prices for.

Setting and wearing yellow topaz

Topaz is hard enough to resist daily scratches, but its perfect cleavage means a sharp knock at the wrong angle can split it. Choose a setting that protects the girdle and corners: a bezel, a half bezel, or sturdy prongs with V-tips on pointed shapes. Yellow gold deepens the warm colour of golden topaz; silver and white gold make pale lemon stones look crisper. Take the ring off for the gym or heavy work, and ask the jeweller to remove the stone before any soldering. Our stone setting service page and the guide to silver and gold settings cover the options, and for size see the ring size guide.

What to ask the seller

1. Is this topaz or quartz? Please write the mineral name on the invoice.
2. Has the stone been irradiated, heated or coated?
3. Is the weight that of the loose, cut stone, in carats?
4. Can you send a video under ordinary room light, turning the stone?
5. Are there any cracks that reach the surface?
6. Is a certificate available, and can independent testing be arranged?
7. Can I inspect it before paying, and return it if it is not as described?

Choosing yellow topaz online in Pakistan

Buying a gemstone online is safe when you can see the exact stone and check it before paying. Look for a listing that shows the stone itself rather than a catalogue image, gives the weight in carats and names the mineral. Compare the photo with a video if you can; yellow stones photograph brighter than they look indoors.

GemStore photographs every stone on its own and prices it on its own. Our topaz collection includes stones such as this natural topaz, alongside blue stones like the 12.60 carat blue topaz. If you want the same golden colour at a lower price, compare a 4.85 carat citrine; if you want the harder, more traditional stone, see a 2.25 carat yellow sapphire. Our planned yellow topaz price guide covers what each level of quality costs, and the yellow gemstones page shows every yellow stone together.

We deliver across Pakistan with Cash on Delivery: open the parcel, check the stone and pay the rider only if you are satisfied. Returns are accepted within 7 days, and a certificate is available on request.
