Opal Buying Guide for Pakistan: How to Choose a Solid, Bright Opal

A good opal is one whose colour flashes are bright from most angles, whose body is solid natural opal rather than a glued layer, and which has no cracks. Brightness matters more than size, and the type of opal decides how carefully you must treat it. If you remember only that, you will avoid most bad buys.

Our opal benefits post covers tradition and everyday care. This guide is about choosing: how to read play-of-colour from photos and video, why Ethiopian and Australian opal behave differently, which treatments to ask about, and what to check when the parcel reaches you anywhere in Pakistan.

Know the main kinds of opal first

Opal is hydrated silica, and the word covers several quite different stones. Sellers in Pakistan do not always say which one they mean, so it helps to know the names.

• Precious opal: shows play-of-colour, the moving flashes of spectral colour. This is what most buyers want.
• Common opal: has body colour, such as pink, blue or green, but no flashes. It is pleasant and far cheaper.
• White or light opal: precious opal on a pale, milky body.
• Crystal opal: transparent to semi-transparent with flashes floating inside.
• Black or dark opal: precious opal on a dark body, which makes the colours look stronger. Fine black opal is the most valuable kind.
• Boulder opal: a thin seam of opal left on its natural ironstone backing.
• Fire opal: orange to red transparent opal, often faceted, with or without flashes.

When a listing just says "opal", ask which of these it is.

Ethiopian or Australian: why it matters to you

Most opal sold in Pakistan comes from Ethiopia or Australia, and the difference affects care as much as price.

Ethiopian (Welo) opal

Most Ethiopian opal is hydrophane, which means it can soak up water. When wet it may turn clearer, lose its flashes or change colour for a while, then return as it dries. That is normal for the material and not a fault, but it means you should keep it away from water, oil and soap. Ethiopian opal often shows bright, broad flashes at a friendlier price, which is why it dominates the Pakistani market. Several of our listings are Ethiopian, such as the 1.50 carat Ethiopian opal and the 1.90 carat Ethiopian opal.

Australian opal

Australian opal is usually non-hydrophane and more stable in daily wear. It includes the classic white, black and boulder types. Good Australian stones cost more for similar flash. Our planned Australian opal buying guide goes further.

Neither is "real" while the other is "fake"; both are natural. Choose by how you will wear it and what you can spend.

Play-of-colour: the heart of the value

Judge the flashes on four points.

Brightness

Brightness is the most important single factor. A bright opal shows strong colour even in ordinary room light. A dull one only lights up under a torch. Ask for a video under normal indoor light as well as the studio photo.

Colours present

Blue and green flashes are the most common. Orange and red are rarer, and a stone that shows red along with the others usually ranks higher.

Pattern

Pattern is the shape the flashes make: pinfire (tiny points), broad flash (large sheets), harlequin (a patchwork of squares) and many others. Pattern is partly personal taste. Large, well-defined patterns tend to be valued above a faint scatter.

Directionality

Turn the stone. Some opals flash from every angle; others only from one direction and look blank from the rest. An opal that shows colour all round is the better buy, especially for a ring that will be seen from many angles.

Body tone and transparency

Body tone is how light or dark the opal's background is, from white through grey to black. A darker body makes the same flashes look more intense, which is why dark opal is prized. Transparency matters too. Crystal opal glows from within; milky opal is softer in look. Neither is wrong. Decide which look you like, then compare stones of the same kind.

Clarity and cracks

Opal is judged for cracks more than inclusions. Look closely for:

• Crazing: a network of fine surface cracks, usually from drying or heat. A crazed opal has lost most of its value and may get worse.
• Potch lines: streaks of colourless common opal running through the precious opal. A little is fine; a lot breaks the pattern.
• Sand or matrix spots: small inclusions of host rock. They lower value if they sit in the middle of the face.

A crack can hide in a photo. Ask the seller directly whether the stone has any cracks or crazing, and look again in daylight when it arrives.

Cut, shape and size

Most opal is cut as a cabochon so the dome can show the flashes. Look for a smooth, even dome without flat spots, and a base that is not left very thick just to add weight. Ovals are the standard; free-form shapes are common because cutters follow the colour bar in the rough.

Size is the last thing to weigh. A bright 1.5 carat opal looks better on the hand than a dull 4 carat one. Our 1.60 carat opal shows how much presence a well-cut small stone can have. Opal is light for its size, so a given carat weight looks larger than a sapphire of the same weight.

If an astrologer has named a weight in ratti, check which ratti. The standard gem ratti in Pakistan is 0.91 carat; the sunari ratti is about 0.61 carat. Use the carat to ratti converter before you compare listings.

Treatments and assembled stones to ask about

Our planned posts on real and fake opal and Ethiopian opal fakes go deeper into each test.

Spending sensibly at each budget

Opal prices spread widely, so decide where your money goes before you start scrolling. At the lower end, spend on brightness and accept a smaller stone or a milky body; a lively little Ethiopian opal is a far better purchase than a large, sleepy one. In the middle, look for flashes from every angle and at least some orange or red. At the top, body tone, pattern and freedom from any crack start to separate one stone from the next, and a certificate becomes worth having. Our shop filters let you start with stones under 5,000 rupees or 5,000 to 20,000 rupees, and the monthly gemstone price guide shows current ranges.

Questions to send before you pay

1. Is it solid natural opal, not a doublet, triplet, synthetic or glass?
2. Is it Ethiopian or Australian, or from elsewhere, and how do you know?
3. Has it been smoked, dyed or otherwise treated?
4. Are there any cracks, crazing or potch lines?
5. Can I see a video in ordinary indoor light, turned slowly?
6. Is the weight that of the finished stone, in carats?
7. Is a certificate available, and can independent testing be arranged?

For GemStore opals the answer to the last question is yes. A certificate is available on request, and lab-certified opals are listed on their own page.

Buying opal online in Pakistan

Opal is the hardest stone to judge from a single photo, because its whole value is in movement. Ask for video, and buy from a seller who photographs the exact stone. Ours ship in 1 to 2 working days by insured, tracked courier and usually arrive in about 7 working days.

With Cash on Delivery you can open the parcel before paying the rider. When you do:

• Turn the stone slowly under a ceiling light and near a window; the flashes should match the video.
• Look at it from the side to make sure there is no glued layer.
• Check the surface for fine cracks.
• Do not wet an Ethiopian opal to test it.

If it is not as described, you have 7 days to return it under our returns policy.

After you buy: setting and care in a Pakistani climate

Opal is 5.5 to 6.5 on the Mohs scale, so it scratches more easily than quartz. Pendants and earrings are the easiest way to wear it. For a ring, a bezel setting protects the edges. Pakistani summers bring heat and very dry air in some cities, so do not leave an opal on a car dashboard or near a heater, and keep it out of hot water. Wipe it with a soft, slightly damp cloth; never use ultrasonic or steam cleaners. The planned how to wear opal post covers finger, metal and tradition.

In Vedic practice opal is associated with Shukra (Venus), and some families choose it for Libra or Taurus. It is also one of the October birthstones. These are traditions, not promises.
