Tests To Identify That The Yellow Sapphire Report Is Real Or Fake?

Yellow Sapphire gemstone is emerging as a popular stone for engagement rings, wedding rings, bracelet and earrings. Its popularity is because of its impelling color that draws others attention. The stunning and appreciating color  of pukhraj stone makes this gemstone as one of the popular stone among the gem family.

Apart from this Yellow Sapphire stone is related to auspicious planet Jupiter, which is the other factor that make this gemstone as a valuable stone.

Since, its popularity is increasing, it is important for you to know that always buy a good quality yellow sapphire for both jewelry and astrological purpose. Only a good quality pukhraj stone can give you the maximum benefits.

Today, I would like to discuss with you some of the Gomological facts related to yellow sapphire stone. In this blog, I will tell you some of the tests that you can do to identify whether a yellow sapphire report is real or not. A few days ago, I came across one of the customers who bought a yellow sapphire from some gem dealer and discuss about his problem that yellow sapphire stone is not showing any effect on him.

When I just saw the yellow sapphire stone, I found something suspicious and I thought that yellow sapphire stone was not right. Although the gemstone have certification, but still didn’t convince with the quality of yellow sapphire. So, I perform some of my tests to check the authenticity of the stone.

1. Beneath The Microscope

This is dependably the fun part where you get the chance to see very close what is truly going on. The primary thing I saw was the inclusions inside the stone. A lot of fluid documented tubes within the stone which had my scrutinizing straight away the wrong gemstone report which says Sapphire. Fluid filled tubes are great incorporations inside stones that frame inside pegmatites (Beryl, Topaz, Quartz). Could the phony gemstone report truly get it so off-base.

Next up I begin to look once again the stone for any hints of whatever else suspicious. On the base of the stone I locate some yellow residue of what resembles dye. Clearly the greater part of the dye has rubbed off and just little sums remain This is what is giving this stone the yellow color.

2. Visual Check Test

These are tests that should be possible with no equipment. In many cases all that is required is your eyes and once in a while perhaps a loupe. So this stone was inadequately cut, nothing astounding there. The stone had a strange color, something that I would not anticipate from a yellow Sapphire.

Clearly by turning the stone, the shading was for the most part originating from the base of the stone and being reflected around. Typically the shading originates from inside the stone and turning it doesn’t change the color of the stone.

3.    Verify The Refractive Index(RI)

This is the nail in the pine box. Every mineral has its own refractive index that is one of a kind. It is one of the primary ways that Gemologists separate between minerals. I put some fluid on the refractive index reader and put the gemstone on the top. Amazingly the RI of this jewel is 1.61 – 1.62. The RI of Sapphire is 1.76 – 1.77 so it’s absolutely impossible this could be Sapphire.

Again  the gemstone report truly gets it so off-base. There is just a single gemstone who’s RI possesses all the necessary qualities, and that is Topaz. It is all becoming alright now, the RI is revealing to me it is Topaz, the incorporations are disclosing to me it is a stone framed in a pegmatite, for example, Topaz and it is colored yellow.

4.    Perform Acetone Test

Just to recheck my doubt, I place the stone in acetone. Then I use nail polish remover as it removes the coating on the stone. I wanted to remove the coating so that I can take again the RI reading. A few hours later, the acetone changed into yellow color and the stone was clear. Then I again take the RI and it was still same as that of Topaz.

5.    Verifying The Gemstone Report

The report was given to the customer with the stone. In this report some of the things were true, but the main component as false. Let me tell you in detail.

  • Firstly, there is no email, website details are given on the report.
  • The dimensions, weight and shape of the stone is fine.
  • The RI is given as 1.76-1.77, that is wrong. According to the above test, the RI of the stone is 1.61-1.62 that is of topaz.
  • The report says that species is Corundum, that is fake since corundum is sapphire or ruby and this stone is topaz.

In a nutshell, I would say that don’t just believe that if the seller is giving you the certification, then that doesn’t mean that this stone is for sure correct. As the above gemstone report that contain all the technical information was false, so just be careful.
