Topaz Price in Pakistan: Colour, Treatment and Comparing Quotes

Few stones cover as wide a price spread as topaz. A big, clean blue topaz can cost less than a small natural pink from Katlang. A "golden topaz" in one shop turns out to be citrine or glass in the next. And some yellow topaz gets sold as pukhraj, a word that in Pakistan ought to mean yellow sapphire. So before you can make sense of a topaz price, you need to know exactly which topaz is on the table.

Below we cover how topaz is priced, why colour and treatment count for more than size, how per-ratti quotes fit in, and how to compare offers fairly. The figures come from the table that follows, which is built from our own topaz listings and refreshed every month.

What our topaz listings show

The table gives the lowest, typical and highest price per stone in our topaz category, plus the matching per-carat and per-ratti figures.

Topaz · October 2026 edition · PKR, from Authentic Gems listings. 1 ratti = 0.91 carat.

Weight	Weights	Stones	Per carat	Per ratti
3 – 6 carat	3.4 – 5.9 ct	9	Rs 2,200 – Rs 4,200	Rs 2,000 – Rs 3,800
6 – 10 carat	7.1 – 9.9 ct	4	Rs 1,100 – Rs 2,100	Rs 1,000 – Rs 1,900
Over 10 carat	12.6 – 19.0 ct	3	Rs 1,300 – Rs 4,200	Rs 1,200 – Rs 3,800

That category mixes several colours, so the spread is wide. We also keep separate blue topaz and white topaz categories. For other stones, see the monthly gemstone price guide.

Topaz colours and how each is priced

Colour drives topaz prices more than anything else, and the colours sort into fairly clear groups.

Imperial and pink

Natural golden-orange to pinkish-orange topaz, usually called imperial, and natural pink topaz sit at the top. Pakistan has a well-known source of natural pink to violet topaz at Katlang in Mardan district, Khyber Pakhtunkhwa, where the crystals grow in an unusual host rock. Good Katlang pink is scarce and people go looking for it. More on our planned Katlang pink topaz page and the planned pink topaz category.

Golden, sherry and brown

Natural yellow, golden and sherry-brown topaz turns up more often than imperial and costs much less, though a bright, clean golden stone still looks lovely. Some brown topaz fades if left in strong sun for long periods, and that affects its value.

Blue

Nearly every blue topaz you will see began life colourless and was irradiated and heated to give it a permanent blue. The trade names describe the shade: Sky blue is pale, Swiss blue is bright and mid-toned, London blue is deep with a touch of grey. Since the rough is plentiful and the treatment routine, blue topaz stays affordable even in big sizes. Our blue topaz post explains why it is treated.

White (colourless)

Colourless topaz is the cheapest per carat. People like it as an affordable, natural bright stone, but it shows dirt and grease quickly. Our white topaz care guide covers keeping it clean.

Coated

"Mystic" and other rainbow topaz carry a thin surface coating that wears away with time and cleaning. Such stones should always be described as coated and priced accordingly.

Where topaz is mined

For topaz, origin counts for less than colour and treatment, with one exception: natural pink from Katlang has its own name and standing in Pakistan. Brazil is the classic source of imperial topaz, especially around Ouro Preto, and also supplies a great deal of the colourless rough that ends up blue. Sri Lanka, Nigeria, Madagascar and other countries produce colourless, golden and pale blue stones. Peshawar has long been a trading hub for stones from Khyber Pakhtunkhwa and beyond, and Katlang topaz often goes through its markets before reaching Karachi and other cities.

As with any gem, an origin claim should only raise the price when a lab report or proper documentation supports it. "Katlang" or "Brazilian imperial" said across a counter, with nothing written, should not shift the number.

How treatment changes the price

• Untreated natural colour: the highest prices, for pink, imperial and fine golden stones.
• Heated: some pink topaz is made by heating certain golden stones. A lab can sometimes detect it; ask the seller to state it.
• Irradiated and heated: standard for blue topaz. Stable, permanent, and the reason blue topaz is affordable.
• Coated: colour on the surface only, the lowest value, and it must be declared.

Clarity, cut and size

Topaz often grows in large, clean crystals, so you can reasonably expect faceted stones, blue and white especially, to look clean to the eye. Visible inclusions bring the price down noticeably. Natural pink and imperial stones are judged a bit more kindly, because clean material is rarer.

Topaz has a bright lustre, and a good cut shows it as lively sparkle with no dark or glassy window in the middle. Topaz also has perfect cleavage, so a careful cutter orients the stone to reduce the chance of splitting. You cannot see that directly, but it shows in the quality of the finish.

With blue and white topaz, size pushes up the total but only nudges the per-carat rate, because big crystals are common. With natural pink and imperial, the per-carat rate rises steeply with size, since large, well-coloured crystals are hard to come by.

Topaz is not pukhraj

In the Pakistani trade, pukhraj means yellow sapphire: corundum, 9 on the Mohs scale. Yellow topaz sometimes gets sold under that name, out of confusion or on purpose, and at a pukhraj price. Topaz is a different mineral, softer at 8, and worth far less than fine yellow sapphire. If you are buying pukhraj for astrological reasons, make sure the invoice says yellow sapphire. Our guides to identifying original pukhraj and the planned yellow topaz buying guide explain the difference. Citrine is another frequent stand-in for golden topaz; see yellow sapphire vs citrine.

Carat and ratti

Labs record topaz in carats, a carat being 0.2 grams. Many buyers here ask in ratti. The standard gemstone ratti is 0.91 carat, so a 13.82 carat topaz comes to about 15.2 ratti. The jeweller's sunari ratti is smaller, about 0.61 carat, so always ask which is meant. Our carat to ratti converter handles both.

To turn a per-carat rate into a per-ratti rate on the standard ratti, multiply by 0.91. Topaz is dense, so it looks a little smaller than a quartz stone of the same weight. Compare face-up size in millimetres as well as carats.

Per-ratti quotes over the counter

When a shop quotes topaz per ratti, check the usual three things: which ratti, whether the weight is for the loose stone, and whether the rate belongs to the stone you are actually buying. Topaz adds a fourth. Get the variety and treatment in writing, because natural pink, heated pink, blue and coated stones are very different on paper but easy to mix up across a counter.

Comparing two topaz offers

1. Same variety: blue against blue, natural pink against natural pink.
2. Same treatment: untreated, heated, irradiated and coated stones are different products.
3. Same unit: bring both to a price per carat.
4. Clarity: check both are eye-clean, or note where they differ.
5. Colour indoors: ask for a video. London blue in particular goes much darker inside.
6. Returns: make sure you can send the stone back if a lab disagrees with the description.

What to ask before paying

Someone who knows topaz will answer these without fuss. Get the answers on WhatsApp so you have them in writing.

• Which variety is it: natural pink, imperial, golden, blue, white or coated?
• Has the colour been heated, irradiated or coated?
• Is it really topaz, or citrine, quartz or glass sold as topaz?
• What is the loose weight in carats, and the size in millimetres?
• Can I see a video in normal indoor light?
• Can I have it tested, and what happens if a lab disagrees?

The ring is priced separately

A loose topaz price does not include a setting. A big blue topaz usually looks best in silver, which keeps the total modest, while natural pink or imperial stones generally go into gold, which adds a fair amount. When comparing a ready-made ring with a loose stone, ask for stone and setting to be priced separately. Because topaz can split along its cleavage, ask the jeweller to set it carefully, with no heavy hammering or heat near the stone. Our planned stone setting service page explains how we can help.

Browsing by budget

Use the shop filters to see what each band holds across all categories, then compare topaz stones of a similar size:

• The lowest price band
• The second band
• The third band
• The top band

In the topaz category, look at stones like this 13.82 carat blue topaz and this natural topaz, and weigh their colour and clarity against the price per carat.

Caring for topaz

Topaz is hard, but its perfect cleavage means a sharp knock can split it. Pick a protective setting for a daily ring, skip ultrasonic and steam cleaners, and keep it apart from harder stones. Our topaz care guide explains why. Topaz is also a November birthstone; see the November birthstone page.
