How to spot fake pearls by simply looking at them?


When you are at a jewellery store and you spot a pearl necklace, the first thing to do is to have a simple observation. Place the pearl necklace on a white sheet of paper and start examining it inch-by-inch. As a student of a jewellery design course would know, you will have to check

  • If they have variations in shape.
  • Look out for any inclusions or blemishes on the surface.
  • Notice if can spot any lighter or darker areas visible just underneath the surface when you hold the pearls up against a strong light source.
  • Look out for subtle variations in body colour or overtone within the necklace layout.


Ask yourself these questions, but remember that cultured pearls are nothing but natural pearls. The mollusks will always leave its mark in the form of a fingerprint on the gem during its creation.

During the tooth test, If it is a natural pearl, you will feel a gritty texture, something like fine-grain sandpaper. The gritty texture feel is due to the microscopic layers of aragonite (crystalline) platelets layered on the top of each other. If it is a synthetic pearl, it feels smooth, like plastic. This happens because man-made gems lack crystalline plates.  These measures are part of training in jewellery designing courses.
