2. Check the luster
Luster is the property or parameter that shows the reflection of light. The finest quality shows a very bright and strong luster, and it almost looks like the light is coming from them. In reality, one can see their reflection if they look closely, whereas this is not possible in a fake. This happens because natural pearl has Iridescence (A phenomena) In this method, real with low quality may be mistaken as fake ones.
3. Check Overtone
It shows a significant amount of overtone. Overtone is the color that appears on the outer surface when light is put on it. Fake ones do not display an overtone effect. It’s easy to tell the difference between a fake and a real one. Pass the light on your pearl stone and look for a slight shade of color when light strikes it. If it shows that little shade, it might be a real one.
4. Observe Near Drill Hole
It is drilled with holes to make necklaces. Carefully observe the whole of it. If you find the edge of a whole with perfectly rounded edges, it is a duplicate. Real ones have imperfectly round holes, and their boundaries are very well-defined. This test plays a prominent role in the identification of pearl stones.
5. Tooth Test
Alternatively, you can try scratching them gently and carefully with your teeth. The real one will make you feel rough, gritty, irregular, or uneven in your teeth. A fake will appear to have a smooth surface on the teeth. This test is a very good and easy test for pearl stone identification.
