Trained eyes cannot always avoid error, particularly, if the gem has been manufactured in the laboratory. It becomes a challenging task. Earlier on a magnifying glass was good enough.

Now however, a host of instruments are used, especially if one wants to be absolutely certain of the gem, its history and pedigree.

It is tricky to test a gemstone. Some stones are soft, some are mounted while some can be coated, treated or easily scratched.

One has to be very careful while testing so as to not to damage the gemstone.

Let’s have a look at the different tools and techniques used by gemologist to test Gemstones:

1.LOUPE

Loupe is nothing but a sophisticated magnifying glass.

It magnifies the gemstone in reveal detail. The internal flaws, surface blemishes, cracks and any other cover ups are easily visible. It is a powerful convex lens that produces a magnified image of the gemstone.

The standard loupe that used is 10X, which magnifies the gem ten times its size.Although some gemologists use a 20X loupe as well

2.BINOCULAR MICROSCOPE

Binocular Microscope is equipped to spread light from the bottom and from the sides.

Its function is similar to the loupe. Presence of the lights and its superior optical strength provides excellent clarity.

It usually has 10X magnification power though 200X can be got. Most common ones are 10X to 40X. There are stages of adjusting the iris diaphragm. It also provides coarse to fine focusing

3.REFRACTOMETER

Refractometer measures the refractive index of the gemstone. This is needed in order to find out its composition and physical properties.

It measures the extent to which the light that passes through the gemstone from the air is bent. It helps identify the gem by comparing the refractive index thus got with the established values.

 It assesses the purity of the gem by comparing it to the value of a natural gemstone. It also determines the amount of solute that has been added to the gemstone by comparing the refractive index thus obtained with the standard curve that is established.  

4.SPECIFIC GRAVITY LIQUIDS

Specific gravity Liquids – this is important for identifying a number of gemstones. A carat scale also called hydrostatic balance is used.

For a person not acquainted with gemology the best way to test the authenticity of the gemstone is to go to any recognized laboratory, spend some money and be clear whether the gemstone is real or fake, treated or poor quality.

We would advise you not to follow the trending, try at home tests, available online as they may damage your gemstone and may cause unwarranted harm.
