Sabz Aqeeq: Green Agate

Sabz Aqeeq is chalcedony in shades of green. The colour can be pale mint, fresh leaf or a deep bottle green, sometimes with fine banding or cloudy patterns. It brings a bold green to a ring at a small fraction of the price of emerald.

The treatment question

Strong, even green rarely occurs naturally in agate. Most vivid green agate on the market has been dyed, often with chromium or nickel salts that give a stable colour. Naturally green chalcedony exists but is usually softer and more muted. Chrysoprase, an apple green chalcedony coloured by nickel, is a different material and priced higher. None of this makes a dyed stone bad; it simply should be priced as dyed. Our listings show what we know about each stone.

When you compare stones, check whether the colour is even or pools in cracks and bands, which can point to dye. Look at translucency too: a stone that glows when held to light looks livelier than an opaque one. Cut matters less than with faceted gems, but a smooth, symmetrical dome or a crisp flat top catches the eye.

Green is a colour with deep cultural meaning across Pakistan, and many people choose a green Aqeeq for that reason alone. Some wear it in place of emerald where tradition allows a substitute. Whether it suits that role is a question for the person who advised you.

Green agate rates 6.5 to 7 in hardness, so it is tough and ready for daily wear in silver or gold. Keep it out of strong sunlight for long periods and away from bleach and solvents, which can lighten dyed colour. Soap and water are enough.
