Pearl jewelry has always been very popular. They set off female beauty, add sophistication and nobility to it. But manufacturers often pass off artificial pearls as natural, hoping for the ignorance of the buyer.
Instructions
Step 1
The surface of natural pearls is not very smooth, because in the shell each layer of the pearl grows unevenly. During a tooth check, when trying to bite a bead from an imitation pearl, the tooth slips off. It is too slippery and smooth. The natural surface is somewhat rough, the tooth clings to it.
Step 2
Natural pearls differ from each other in size, shape and shade. They grow inside mother-of-pearl shells in natural conditions, so they cannot be exactly the same. Artificial beads are absolutely indistinguishable from one another, since they are produced in factories.
Step 3
You can check the naturalness by rubbing. Take two pearls and rub them together with a little effort. The finest dust will appear between the authentic ones. After wetting, there will be no traces of friction.
Step 4
You can use a special jewelry tomograph. To do this, you will have to contact a laboratory or jewelry workshop. The device will illuminate the bead. In cultured pearls, a clear, rounded nucleus is visible. Naturally, the contours of the nucleus are blurred and do not have a spherical shape. The imitation has a thin and very clear layer on the surface. The tomograph will be able to determine the origin of pearls - in the sea there is a higher content of manganese in comparison with the river one.
Step 5
If you bought expensive jewelry, you can test the naturalness of the jewelry with a nail file. Select the bead next to the clasp and rub it with a nail file. The mother-of-pearl dyed faux pearl will wear off the top coat to reveal the base.
