Tanzanite Price in Pakistan: Colour, Size and How to Compare Quotes

Tanzanite is priced mainly on the depth of its blue-violet colour, and size has an unusually strong effect, because small tanzanites tend to look pale and only larger stones show a rich colour. Clarity, cut and whether the stone is coated come next. Since tanzanite is mined in only one small area of Tanzania, supply is limited, but the stone is still far more affordable than a blue sapphire of similar look.

This guide explains each price factor, how per-carat and per-ratti quotes work in Pakistan, and how to compare offers fairly. Rather than typing figures, we show a table built from our own listings and refreshed monthly. To see each stone photographed on its own, browse our tanzanite collection.

Tanzanite prices from our listings

The table gives the lowest, typical and highest price per stone in our tanzanite listings, plus the same figures per carat and per ratti.

Tanzanite · October 2026 edition · PKR, from GemStore listings. 1 ratti = 0.91 carat.

Weight	Weights	Stones	Per carat	Per ratti
3 – 6 carat	4.2 – 5.8 ct	6	Rs 1,900 – Rs 4,900	Rs 1,750 – Rs 4,500
6 – 10 carat	6.1 – 6.3 ct	2	Rs 2,000 – Rs 7,500	Rs 1,800 – Rs 6,800

The spread in the table is mostly a spread in colour and size. Two stones of the same weight can sit at opposite ends because one is a pale lilac and the other a deep violet-blue. For prices across all stones, see the monthly gemstone price guide.

Why tanzanite is priced the way it is

Tanzanite is a blue to violet variety of the mineral zoisite. It was discovered in the 1960s in a small area near Mount Kilimanjaro, and that area is still its only commercial source. A single source makes supply sensitive to mining conditions, so prices are less settled than for stones mined in many countries.

Almost all tanzanite is heated. Rough crystals come out of the ground with brown, yellow or greenish tones, and gentle heating removes them to leave the blue-violet. This is standard and stable, and it is priced in: an unheated tanzanite is not normally sold at a premium the way unheated sapphire is.

The factors that set a tanzanite's price

1. Colour depth

Saturation is the biggest single factor. The trade uses letter grades such as A, AA, AAA and AAAA to describe colour depth, but these labels are not standardised. One seller's AAA can be another's AA. Treat the letters as a seller's opinion and judge the colour from photos and video instead.

• Pale lilac or light lavender: the most affordable. Pretty in daylight, but can look washed out indoors.
• Medium blue-violet: the middle of the market and a good balance of colour and cost.
• Deep, saturated violet-blue: the most valued. The richest stones keep their colour in all lighting.

2. Blue versus violet

Tanzanite is strongly pleochroic: it shows blue, violet and a burgundy tone along different directions. The cutter chooses which colour faces up. Stones that face up more blue are often priced higher than those that face up more violet, because blue is in greater demand, though tastes vary. Look at the stone in daylight and under indoor bulbs: tanzanite tends to look bluer in daylight and more violet under warm light.

3. Size

Size affects tanzanite more than many stones. The colour of tanzanite depends on how much stone light travels through, so small stones tend to look paler. A deep colour is far easier to find above a few carats. That means the price per carat climbs with size, and a small stone with genuinely deep colour is uncommon. Convert sizes with our carat to ratti converter.

4. Clarity

Good tanzanite is usually eye-clean, and buyers expect it to be. Visible inclusions, cracks or cloudiness lower the price substantially. Feathers near the girdle matter more than for many stones, because tanzanite has cleavage and a crack there can spread.

5. Cut

A well-cut tanzanite is lively across the face with no dull window in the centre. Cutters sometimes leave a stone deep to keep weight and colour; this adds carats you pay for and can make the stone look darker but smaller face-up. Compare the face-up size, not only the weight.

6. Shape

Tanzanite rough often comes in long, flat crystals, so cushions, ovals and trillions are common, and cutters choose shapes that save the most weight. Rounds waste more rough and can cost a little more per carat. Shape choice also affects colour: a stone cut to face up along its blue direction may lose weight in the process, which is one reason the bluest stones carry a higher rate. For a ring, cushions and ovals with rounded corners are the safer choice, since sharp points chip more easily.

Coatings, look-alikes and synthetic stones

These are the main reasons a "tanzanite" quote can be too low:

• Coated tanzanite: a thin film on the surface, sometimes containing cobalt, deepens a pale stone. It can wear away with cleaning and everyday wear. Coated stones must be disclosed and should cost much less. Ask directly whether the stone is coated.
• Iolite: a cheaper violet-blue stone that also changes colour with angle, usually to grey or yellowish, without tanzanite's burgundy flash.
• Synthetic forsterite and glass: man-made stones that copy tanzanite's colour. Forsterite can fool buyers by eye; a lab separates it easily. Glass often shows bubbles and shows one colour from every angle.
• Blue topaz or treated quartz sold as tanzanite: wrong colour balance and different optics.

A vivid, flawless, large tanzanite at a low price is the classic warning sign. Get "natural tanzanite, heated, not coated" written on the invoice for anything costly. Our article on tanzanite in tradition and practice covers more on telling it from iolite and glass.

How per-ratti pricing works for tanzanite

Tanzanite is often quoted per carat by importers, but some Pakistani sellers quote per ratti, particularly when it is sold as an alternative to neelam for astrology. Before comparing quotes:

• Ask which ratti. The standard gemstone ratti is 0.91 carat (about 0.182 g); the jeweller's sunari ratti is about 0.1215 g, or 0.61 carat. A per-ratti price on the smaller ratti looks lower but buys less stone.
• Remember that rate rises with size. A flat per-ratti rate for all sizes usually means the colour is not consistent across them.
• Use loose stone weight only, never a ring weight.

How to compare two tanzanite quotes

1. Confirm in writing that each stone is natural tanzanite, heated, and not coated.
2. Get weight in carats, and the face-up dimensions in millimetres.
3. Ask for video in daylight and under indoor light, turning the stone.
4. Compare colour depth first, ignoring letter grades.
5. Check for a dull window or visible inclusions.
6. Compare face-up size, then price per carat.

If one quote is far below the others for a similar-looking stone, the reason is usually coating, a look-alike stone, or the smaller ratti.

Tanzanite against blue sapphire on price

Many buyers in Pakistan compare tanzanite with blue sapphire (neelam). Tanzanite gives a large, rich blue-violet stone for a much smaller budget than a neelam of the same size and colour. In exchange it is softer, at about 6 to 7 on the Mohs scale against sapphire's 9, and it has cleavage, so it needs more care in a ring. Some astrologers accept tanzanite as a Saturn alternative, many do not; these are beliefs, not promised results, so ask your adviser before choosing it on astrological grounds. For neelam, see blue sapphire prices.

Budget tiers by filter

These links show all stones in the shop; narrow them to tanzanite on the page that opens.

• Under 5,000 rupees: expect smaller or lighter stones in this band, if any are listed; check the table above.
• 5,000 to 20,000 rupees: compare colour depth closely here, since lilac and medium stones sit side by side.
• 20,000 to 50,000 rupees: larger stones where richer colour becomes easier to find.
• Over 50,000 rupees: the band for larger stones with deep, saturated colour and clean clarity.

Two stones from our collection show how size changes the look: a 2.18 carat natural tanzanite and a 4.70 carat natural tanzanite. Compare their photos to see how a larger stone carries deeper colour.

Protecting a tanzanite's value

A chipped or cracked tanzanite loses much of its value. Choose a protective setting such as a bezel for a ring, or wear it as a pendant or earrings. Remove a tanzanite ring for gym, sport and household work. Clean it with mild soapy water and a soft brush, never in an ultrasonic or steam cleaner, and avoid sudden heat. Store it away from harder stones.

Tanzanite is one of the modern December birthstones, alongside turquoise. Our December birthstones guide compares it with feroza and lajward, and our blue gemstones and purple gemstones pages show other stones in the same colours.

Does a certificate help?

For a costly tanzanite, yes. A lab can confirm the stone is natural zoisite, separate it from synthetic forsterite and glass, and detect surface coating. A certificate is available on request, and independent lab testing can be arranged. Our guide on reading a lab certificate explains what the report will show.
