Aqeeq in Every Colour: Carnelian, Black, Sulemani, Moss and More

Few stones are as close to everyday life in Pakistan as Aqeeq. It is set in rings, carved into seals, engraved with names and verses, and given as gifts. In English most of it is agate or carnelian. Both are forms of chalcedony, a fine-grained quartz around 6.5 to 7 in hardness, which makes Aqeeq a sturdy, practical ring stone.

Agate, carnelian and chalcedony

Chalcedony is the family name. When it is evenly coloured and translucent, it gets a name by colour, such as carnelian. When it shows bands or patterns, it is called agate. Chalcedony is slightly porous, which matters because it is what makes dyeing possible. Dyeing agate is an old craft, practised for centuries, and a dyed agate is still natural chalcedony underneath.

Carnelian (Aqeeq, Yemeni Aqeeq)

Carnelian is translucent orange to red chalcedony coloured by iron. Held to the light, a good carnelian glows like a coal. Much carnelian on the world market is ordinary chalcedony that has been heated to deepen its colour, since heat turns iron compounds redder. Some is also dyed. Natural colour tends to look slightly cloudy or uneven, with soft variations. Yemeni Aqeeq has long held a special place in Muslim tradition, and many people prefer it for rings. See carnelian Aqeeq.

Red Aqeeq (Surkh Aqeeq)

Red agate ranges from brick red to deep blood red, often with faint banding. Natural red agates exist, and many are also heated or dyed for depth and evenness. Strongly uniform crimson is often a sign of dye. See red agate, and our red stones guide for telling it from carnelian and coral.

Black Aqeeq (Kala Aqeeq)

Here is a fact many sellers skip: nearly all black agate on the market is dyed. Truly black natural chalcedony is rare. The traditional method soaks grey agate in a sugar solution and then treats it with acid, which carbonises the sugar inside the pores. The result is a deep, even, stable black. It is a long accepted treatment, but it should be stated. See black agate.

White Aqeeq (Safaid Aqeeq)

White to milky grey chalcedony, sometimes with faint bands. Most white agate is natural colour, though some is bleached to look cleaner. It is a quiet, elegant stone and pairs well with silver. We carry white agate in our collections too.

Green Aqeeq (Sabz Aqeeq)

Most bright green agate is dyed. Its colour often looks too vivid and even, and dye may gather along bands and fractures. Natural green chalcedony exists, chrysoprase being the best known, coloured by nickel, but it is a different and pricier material. Muted, earthy greens may be natural. See green agate.

Yellow Aqeeq (Zard Aqeeq)

Yellow to honey agate occurs naturally, often with soft banding. Very bright lemon or saturated orange-yellow may be dyed or heated. It is a warm, affordable stone. Our yellow agate sits alongside the other colours in the shop.

Sulemani Aqeeq

Sulemani agate shows bold, contrasting bands, usually black or dark brown with crisp white lines. It is essentially banded onyx. Natural examples exist, but strong black and white contrast is very often enhanced by the same sugar and acid process used for black agate. The name carries religious associations in local tradition, and many people wear it as a stone of protection by custom. Some prized pieces show eye-like rings. See Sulemani agate.

Moss Aqeeq

Moss agate looks as though tiny green plants are trapped inside clear or milky chalcedony. They are not plants. The "moss" is made of mineral inclusions, usually iron or manganese compounds, that grew in branching patterns. Every piece is different, and the colour is natural. See moss agate.

Is dyed Aqeeq a fake?

No. Dyed agate is real agate with added colour. The problem is only when dyed stones are sold as natural colour at natural-colour prices. You can learn the signs in our home checks guide:

• Colour concentrated in cracks and along band edges.
• Colours that are unusually bright or perfectly even.
• Colour lifting onto a cotton bud with acetone, though many dyes are stable and will not lift.

Glass and plastic imitations are a separate problem. Glass shows round bubbles under a loupe and has no banding structure.

Aqeeq in Pakistani tradition

Aqeeq rings are worn by many Muslims across Pakistan as a matter of Sunnah tradition and family custom. Engraved stones carrying names, prayers or verses are popular gifts, especially for weddings and for pilgrims returning from Hajj or Umrah. Many people wear Aqeeq in silver, following long custom. These are traditions, held with affection. We describe them as such and make no promises about effects.

Buying tips

• Agate is light, so large stones stay comfortable. A 10 to 15 ct cabochon is a normal men's ring size.
• Look for even polish without pits, and no cracks crossing the stone.
• For engraving, choose a flat or gently domed top with no surface-reaching cracks.
• Prices are modest compared with sapphire or ruby. Check our price list.
