The Yellow Sapphire Stone, also known as the Pukhraj Stone (Hindi name), is a precious gemstone that represents Jupiter’s planet in Vedic Astrology. Jupiter, or Brihaspati, is the biggest planet in the solar system. In Hindu astrology, Brihaspati is responsible for wisdom, wealth, and knowledge. If Guru Graha is seated in a malefic position, it gives negative results. At the same time, if seated in an auspicious home, it will bless the bad with positive results.

The Pukhraj gemstone helps to reduce the bad effects of Brihaspati Graha. But it is not necessary that it be recommended for only those who have Jupiter in a malefic home. Sometimes it is also recommended for people to increase the good effects.

Yellow Sapphire Stone Identification

Some tests for Yellow Sapphire Stone Identification, which can be done by anyone,

1. The Touch Test

This gemstone is naturally cool. So place the stone on your skin. If it gives a cooler feeling, then it is original; if it gives the opposite feeling within a few seconds, then it is not original.

2. Physical examination

Through sunlight: Place a piece of white cloth over the Pukhraj and place it in the sun. If you notice a sharp yellow tint where the sunlight reflects, then it is original.

Sharp edges: It is one of the hardest gemstones; it is very hard to cut it. So, if a stone has an extremely sharp edge, then the chances of it being a natural gemstone are high.

Bubbles: If yellow sapphire stones were made of glass, then they would have air bubbles inside. On the contrary, an original yellow sapphire would not have any traces of bubbles.

3. Scratch Test

Yellow sapphire scales at 9.0 on the Mohs scale, which means it is very hard. If you rub the stone with some hard substance and it gets scratched, then surely the stone is not original.

4. The Milk Test

Keep the gem in a cup or glass of milk. If you see any colour change, then it is not original. The original gemstone will not show any colour change.

5. The Weight Test

A natural yellow sapphire is heavy. Hold the stone in your hand and try to measure its weight. If it doesn’t feel heavy and weighs less, it’s a fake stone.

6. Fingerprint Test

If you know how to hold a lens and use it to examine a gemstone, then it’s great for you. The pattern of fingerprints that we see inside the sapphire stone is not found in any other stone. Examining some stones will help you understand the pattern, and you will be able to tell the difference between real and fake.

7. Observe the pattern of inclusion

Use a magnifying glass to closely examine the gemstone for any inclusions, growth patterns, or irregularities. Most of the synthetic or fake stones contain inclusion which will be in patterns, which means they are made artificially not naturally. Genuine yellow sapphires have inclusions that would not be in any pattern.

8. UV light Test

Shine the UV light onto the yellow sapphire. If it’s genuine, it may exhibit a weak to moderate blue fluorescence. whether a normal stone especially one that is non-fluorescent, will typically not emit any visible fluorescence. This means the stone emits a bluish glow when exposed to UV light. However, remember that this is just a clue for yellow sapphire stone identification and not a definitive test. It’s best to combine it with other identification methods or consult a professional gemologist for a more accurate assessment.


The above tests can assist in determining originality, but they should not be considered the final test for YELLOW SAPPHIRE IDENTIFICATION. Furthermore, one cannot be sure whether the original gemstone is heat-treated or not. If pukhraj is heat treated, it will not give astrological benefits. So the best and last way to test originality and authenticity is to get it tested through a government-certified or trusted gemology lab. The gemological laboratory checks for originality and also checks if the gemstone has undergone any heat or color enhancement treatment.
