Yellow agate, which we sell as zard aqeeq, is one of the gentler aqeeq stones on the pocket. Even so, two stones that look similar in a photo can be priced quite differently. Almost all of that gap comes down to three questions: is the colour natural, how much does the stone glow, and how well was it finished? Here is how we answer them.
Is the colour natural or dyed?
This makes the biggest difference. Natural yellow agate is usually a soft honey, lemon or golden shade, often with gentle shifts in tone and faint banding. A very bright, flat, almost neon yellow is nearly always dyed. Dyed agate is common and is not a problem in itself, but it should cost less and be sold as dyed. Under a loupe, dye tends to gather along cracks and at the edges of bands.
Does it glow?
Hold the stone up to a light. Good yellow agate is translucent and lights up warmly from inside. Flat, opaque stones look lifeless once set, and they are priced lower.
Is the colour even?
An even colour across the face, or attractive banding sitting in the right place, adds value. Blotches, grey areas and dark spots take it away.
Finish and size
A symmetrical shape, a smooth glassy polish and clean, unchipped edges all count. Size matters too, but a big dull stone is usually worth less than a smaller bright one.
Do not get caught by glass
Yellow glass is the usual imitation. Under magnification it shows round bubbles, and it warms quickly in your palm while agate stays cool. A flawless, perfectly even and very cheap stone deserves a second look. Ask the seller to write that it is natural agate and whether it has been dyed.
Wearing it
Yellow agate is 6.5 to 7 on the Mohs scale, so it is fine in a ring worn daily. Clean it with mild soap and water and keep harsh chemicals away, as they can affect dyed stones.
Before you pay
Make sure the stone is natural, any treatment is in writing and the weight is the cut stone's weight. We check every stone and photograph each one on its own, so you can judge its colour and glow from the listing. Browse yellow agate, or compare bloodstone and jade.
