Real vs Fake Pukhraj (Yellow Sapphire): How to Spot a Fake

Q: How can I tell if a Pukhraj is real?

Check hardness and price together, look for gas bubbles that signal glass, rule out softer look-alikes like citrine, and buy with a certificate from a recognised lab.

Pukhraj (Yellow Sapphire) is one of the most widely worn jyotish stones, so it is also one of the most faked. Yellow glass, citrine and yellow topaz sold under the wrong name, and lab-grown sapphires are all passed off as natural Pukhraj, often at natural prices. A few simple checks, plus a proper certificate, will keep you safe. Here is how to tell a real Pukhraj from a fake before you buy.

The common fakes to watch for

Type	What it is	Tell-tale sign
Yellow glass	Coloured glass cut as a gem	Round gas bubbles inside, very clean, softer
Citrine or yellow topaz	Cheaper yellow stones sold as pukhraj	Softer than sapphire, certificate names the mineral
Lab-grown sapphire	Real chemistry, made in a lab	Very clean, cheap, certificate says synthetic or created
Diffusion-treated	Colour added to the surface	Colour concentrated at facet edges, noted by a lab

Simple checks you can do

Check hardness and price together. Real sapphire is very hard (9 on the Mohs scale) and never cheap. A soft, large, low-priced “pukhraj” is usually glass, citrine or topaz.
Look for bubbles. Round gas bubbles almost always mean glass. Natural inclusions look like fine threads or crystals, not perfect spheres.
Mind the look-alikes. Citrine and yellow topaz are different, softer stones. Only a certificate confirms true yellow sapphire.
Watch for too clean. A flawless, glassy stone at a low price is a warning sign.

The eye can be fooled, and a good fake looks convincing. The certificate is the one check that cannot be argued with.

The only sure test: a certificate

Home checks catch the obvious fakes, but they cannot confirm whether a stone is natural, synthetic or treated. For that you need a report from a recognised lab. A genuine certificate states that the stone is a natural yellow sapphire, notes any treatment, and carries a report number you can verify. When you buy by certificate, you are not relying on a photo or a promise.

Common questions

How can I tell if a Pukhraj is real?

Check hardness and price together (real sapphire is very hard and never cheap), look for gas bubbles that signal glass, rule out softer look-alikes like citrine, and above all buy with a certificate from a recognised lab.

Is citrine sold as pukhraj?

Yes, often. Citrine and yellow topaz are cheaper yellow stones sometimes sold as yellow sapphire. A certificate naming the mineral is the clear answer.

Is a cheap yellow sapphire always fake?

Not always, but be careful. Natural pukhraj is valuable, so a large, clean stone at a very low price is usually glass, a look-alike or lab-grown.

Does a lab-grown yellow sapphire work for astrology?

In Vedic tradition, no. Only a natural pukhraj is worn as a Jupiter (Guru) remedy. Lab-grown stones are treated as jewellery.

What hardness is real pukhraj?

Yellow sapphire is a corundum with a hardness of 9 on the Mohs scale, second only to diamond, which is far harder than glass, citrine or topaz.
