Ethiopian opal changed the opal market. Before large deposits were found in Ethiopia's Welo region, a bright opal with strong colour flashes was beyond most Pakistani buyers. Ethiopian material made bright, transparent to milky opal with lively play-of-colour widely available, and much of the opal now offered in Pakistan comes from there.
That does not make every Ethiopian opal cheap. Prices still vary a great deal between stones of the same weight, and the reasons are mostly visible once you know where to look. This guide explains them, shows GemStore's own price range in the table below, and sets out how to compare per-carat and per-ratti quotes. For checking authenticity, read our Ethiopian opal real or fake guide.
GemStore's Ethiopian opal prices
The table is built from our own Ethiopian opal listings and refreshed monthly. It shows the lowest, typical and highest price per stone, and per carat and per ratti.
| Weight | Weights | Stones | Per carat | Per ratti |
|---|---|---|---|---|
| Under 3 carat | 1.5 – 2.7 ct | 4 | Rs 3,100 – Rs 5,000 | Rs 2,800 – Rs 4,600 |
| 3 – 6 carat | 3.0 – 5.4 ct | 12 | Rs 1,700 – Rs 8,300 | Rs 1,550 – Rs 7,600 |
| 6 – 10 carat | 6.1 – 8.7 ct | 5 | Rs 1,600 – Rs 2,500 | Rs 1,450 – Rs 2,300 |
The per-ratti column uses the standard gemstone ratti of 0.91 carat. Prices are for loose, solid opal; doublets, triplets and set rings are different products. For other opal types and other stones, see our monthly gemstone price guide and the general opal price guide.
What makes Ethiopian opal different
Most Ethiopian gem opal is hydrophane: it is slightly porous and can absorb water. When wet, a hydrophane opal may turn more transparent and its play-of-colour may fade for a while; as it dries over hours or days, it usually returns to its normal look. This is a natural property, not a defect, but it affects how you buy, clean and price the stone. A stone that has been well dried and has proved stable after cutting is worth more than freshly cut material that might still craze (develop fine surface cracks).
Compared with Australian opal, Ethiopian stones tend to be brighter for the money, more often light or crystal in body, and softer in feel, because of that porous structure. Our planned Australian opal price guide covers the other side of that comparison.
What sets the price
1. Brightness of the play-of-colour
This is the first thing any dealer looks at. Hold the stone under a single light, ideally daylight from a window, and tilt it. A top stone flashes strongly from almost every angle. A weaker stone shows colour only at certain angles, or only dimly. Brightness matters more than size: a small, very bright opal can be worth more than a large, sleepy one.
2. Colours present
Flashes of blue and green are the most common. Stones that show strong orange and red flashes as well, across the whole face, are scarcer and priced higher. A full spectrum of colours moving together is what buyers usually mean by a "fire" opal in the bazaar, although strictly that term means a different, orange-bodied opal.
3. Pattern
The way colour is arranged also affects value:
- Pinfire: many small points of colour. Common and attractive.
- Broad flash: large patches of colour that light up as you turn the stone.
- Honeycomb or cell pattern: colour arranged in small cells, a pattern closely associated with Ethiopian opal and sought after by collectors.
- Harlequin or mosaic: distinct, angular patches of colour. Rare and priced well above ordinary patterns.
4. Body tone and transparency
Ethiopian opal ranges from white (milky) through crystal (transparent) to darker browns. Crystal stones with bright colour are popular because the flashes seem to float inside the stone. Very milky stones can look flat. Natural dark-bodied Ethiopian opal exists but is less common; much "black Ethiopian opal" on the market has been smoked or dyed, which brings the next factor.
5. Treatment
Because hydrophane opal absorbs liquids, it can be treated easily:
- Smoking: heating the stone with smoke so carbon darkens the surface layers, giving a black body that makes colour stand out.
- Dyeing: soaking in dye or sugar-and-acid solutions to darken the body.
Treated stones should cost far less than natural ones of similar appearance, and the treatment must be disclosed. A dark Ethiopian opal at a low price is often treated. We disclose treatments where known.
6. Clarity and stability
Cracks, crazing, sand-like inclusions or patches of common (colourless) opal reduce value. Look across the surface under light for fine lines. A stone that has been stable for some time after cutting carries less risk.
7. Cut, shape and size
Most Ethiopian opal is cut as a cabochon, with a dome that shows colour from all sides. Faceted Ethiopian opal also exists, mostly in crystal material. A symmetrical shape and a good dome add value; a thin, flat stone or a lopsided outline lowers it. Size increases price, but less steeply than brightness. For a ring, many buyers choose stones of a few carats, such as our 1.50 carat Ethiopian opal or the 1.90 carat Ethiopian opal.
8. Solid or assembled
Doublets (a thin slice of opal on a backing) and triplets (with a clear cap on top) are made from Ethiopian material too. They are legitimate when sold as such, but they should cost a fraction of a solid opal of the same face size. Look at the stone from the side for a straight join line.
Per-ratti and per-carat pricing
Opal in Pakistan is often quoted per ratti, especially when bought on an astrologer's advice. The total is the weight in ratti multiplied by the rate. Two scales are in use:
- Standard gemstone ratti: 0.91 carat (about 0.182 g). GemStore uses this.
- Jeweller's sunari ratti: about 0.61 carat (0.1215 g).
A 1.82 carat opal is 2 standard ratti but about 3 sunari ratti, so a quote "per ratti" means little until you know which ratti. Ask for the weight in carats, then convert with our carat to ratti converter and work out the price per carat for every quote.
One extra point for hydrophane opal: a stone that has just been washed or soaked may weigh very slightly more than when dry. It is a small effect, but stones should be weighed dry.
How to compare quotes
- Ask for a video as well as a photo. Play-of-colour only shows when the stone moves. A still photo with flash can make any opal look bright.
- Confirm solid, natural and untreated in writing. Otherwise you are comparing different products.
- Compare similar brightness and pattern. A bright honeycomb stone and a faint pinfire stone are not alternatives at the same price.
- Compare similar sizes and convert everything to price per carat.
- Weigh the terms. Cash on Delivery with inspection before payment and a return window has real value for a stone you cannot fully judge from a screen.
Budget tiers
Our shop's price filters group all stones into four bands. Check the table above to see where our Ethiopian opal falls, then use the filters:
- under 5,000 rupees: smaller stones and gentler play-of-colour. Choose for even colour across the face rather than size.
- 5,000 to 20,000 rupees: ring-size stones with clear, lively flashes from several angles.
- 20,000 to 50,000 rupees: bright stones with strong colour across the face, better patterns and good size.
- over 50,000 rupees: exceptional brightness, rare patterns or large clean stones. Ask for a lab report at this level.
The filters cover every category, so choose opal from the list, or go straight to our opal collection, where the origin is given in each stone's name when known.
Reading a listing photo
Because opal is priced on what the play-of-colour does, photos matter more than for most stones. A few habits help when comparing listings online:
- Check the background. Opal photographed on black looks brighter than the same stone on white. Compare stones shown on similar backgrounds, or ask for both.
- Look for more than one angle. A single angle can catch the one bright flash a stone has. Several angles, or a short video, show how much of the face lights up.
- Ask about the light. Strong spotlights make opal flash; overcast daylight is a fairer test of how it will look on your hand.
Every GemStore opal is photographed on its own, and we are happy to send extra angles or a video before you order.
Looking after the value
Opal is about 5.5 to 6.5 on the Mohs scale, softer than most ring stones. Protect what you paid for:
- Do not soak an Ethiopian opal, and keep it away from oils, perfume and creams, which a hydrophane stone can absorb and which can discolour it.
- Clean it with a soft, slightly damp cloth only. No ultrasonic or steam cleaners.
- Avoid sudden heat and long hours in strong sun.
- A bezel setting protects the edges in a ring; pendants and earrings face less wear.

Opal and tradition
Many Pakistani buyers choose opal on an astrologer's advice, as a stone linked with Venus (Shukra) and often suggested in place of diamond. That is a belief, not a promised result. Our opal benefits article covers it, and opal is also a modern October birthstone, on our October birthstone page.
