Generally, the natural gemstones including diamond, opal, emerald, ruby, sapphire, etc., which are precious and valuable. The manmade gems look exquisite too, but they do belong to the fake gemstone category. Manmade gems can be divided into four types: the first one is the imitation which is made of plastic,glass; the second one is the imitation which used the fake stone that similar to the real gems; third one is the counterfeit diamond which is made from some chemical synthesis, such as the alumina; the last one is the transparent mineral which is added with pigment in order to pose as gems. These four categories may sound so confusing and next we will share some tips together, which will help us to identify the natural gemstone from the fake one.
1.Observe the appearance
The natural gems have clear and natural lines and can be characterized as cloud and crystal. The manmade gems have no natural lines. No clouds and crystal characteristics, either.
2.Judging from the ability of heat transfer
The heat transfer of the natural gemstone is slow after being heated. If you touch it,you still feel cool instead of thermal. And the fake one is just the opposite.
3. Take the rigidity into consideration
The rigidity of diamond is 10 degrees, ruby and sapphire is 9 degrees. Other's rigidity is little low than these two numbers. So here we can take the diamond as touchstone. Choose a site where it will not affect the whole appearance of the gems. Then use the diamond scratch on the site slightly. If there is scratch, then this stone is genuine.
4. Pay attention to the color and luster
The natural gemstones are various in the color, such as red, blue,green, orange, purple, yellow and other colors. Take the ruby for example; the best color for this gemstone is the Pigeon Blood.Examine the natural stone with a magnifying glass, you will find some inclusion and crack inside of the stone. The manmade gems look so pure and unadulterated. You will find bubbles and the trace of casting in it if you look carefully.
5. Take the pleochroism into account
The natural gems have pleochroism. When you overlook the sapphire in the sunshine, the color you will see is blue. When you observe it from the side view, the color will change into the blue-green. The fake one has no such features.
6. Using the fire cautiously
You can some extreme examine methods, such as the fire. The real gems will not fall apart when it is burned in the fire while the fake stone will when the temperature rise to 80 degrees Celsius.
No one wants to buy the fake gems as the fake one is valueless. As long as you keep these six tips in mind, next time when you need to choose the engagement ring or your grandma's birthday gift, you will be more confident in what you chose.
