1、 The simplest way to identify diamonds
1. Pencil identification method
Item Preparation: Pencil&Diamond&Pot of Water
Inspection process: Soak the diamond in water and create scratches on the surface of the diamond with a pencil.
Inspection standard: Genuine diamonds will not have pencil scratches in this situation, while diamonds made of other materials will leave corresponding marks.
2. White paper identification method
Item Preparation: Pencil&White Paper&Diamond
Inspection process: Draw a line with a pencil on a white paper, place the diamond on this line, and observe for the presence of the line.
Inspection standard: If you can see the line drawn on a white paper through a diamond, it proves that the diamond is fake; On the contrary, if you cannot see this line, it can prove that this diamond is real.
3. Oil pen identification method
Item Preparation: Oil Pen&Diamond
Inspection process: Use an oil pen to leave scratches on the surface of the diamond.
Inspection standard: If the scratch lines are smooth and clear, it proves that the diamond is genuine; If the scratch lines on the oil pen are intermittent or completely absent, it proves that the diamond is fake.
2、 Using the properties of diamonds to verify their authenticity
1. Testing the hardness of diamonds
Item Preparation: Diamonds&Knives
Inspection process: Pick up the small knife and conduct a scratch test on the diamond.
Inspection standard: If there are no small knife scratches left on the diamond, then the diamond is a genuine diamond; If there are small knife scratches left on the diamond, then the diamond is not a real diamond.
2. Testing the thermal conductivity of diamonds
Item Preparation: Diamonds&Glass
Inspection process: Place the diamond and glass in a common environment, and let two people breathe into both items at the same time, waiting for a few seconds.
Inspection standard: If the water vapor on the diamond dissipates faster than the water vapor on the glass, it proves that the diamond is a real diamond; If the water vapor on the diamond dissipates slower than the water vapor on the glass, it proves that it is not a real diamond ring.
3. Test the reflection quality of diamonds
Item Preparation: Magnifying Glass&Diamond
Inspection process: Observe the reflected light on the diamond waist circumference with a magnifying glass
Inspection standard: If the reflected light on the waist circumference of the diamond appears frosted and is accompanied by dazzling and shiny characteristics, it proves that the diamond is a real diamond; On the contrary, it is a fake diamond.
4. Test the color of diamond reflection light
Item Preparation: Artificial Zirconia Imitation&Diamond
Inspection process: Rotate two items simultaneously and observe the color of the reflected light
Inspection standard: The light reflected by the artificial zirconia replica during rotation is colorful; The color of light reflected by diamonds during rotation is only a faint yellow blue.
