Identification tips / how to check?

1. Look for some Imperfections

Natural pearl stone is usually not perfect. Tiny blemishes and irregular surfaces are very common in these. A natural pearl’s outer surface will reflect light differently in different parts of this gem when light passes on it. Also, a fake one will look perfectly spherical.

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. On looking closely, one can see their reflection in reality, whereas it’s not possible in a fake. In this method, Real with low quality may be mistaken as fake ones.

3. Overtone Test

It shows a significant amount of overtone. Overtone is the color on the outer surface that shows up when light is passed on it. Fake ones do not display an overtone effect. It’s easy to differentiate 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. Drill Holes Test

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.

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 give a feeling of a smooth surface on the teeth.
