Pearl jewelry has always been a favorite of many girls, regardless of age, whether they are dressed elegantly or simply.
Pearl makes women gentler and more elegant. With the growing popularity of pearls, there are an increasing number of pearl ornaments and products on the market.
Fake pearls appear in an infinite number, and distinguishing between true and false is difficult. If you are not cautious, you will purchase fake pearls.
So, what is a quick way to identify pearls?
First and foremost, we must understand the various types of fake pearls on the market in order to quickly identify which are genuine.
The term “fake pearl” refers to all or part of the synthetic imitations and substitutes. Because of its strong simulation, it frequently causes confusion between the true and false.
Wax filled glass imitation pearls, solid glass imitation pearls, plastic coating imitation pearls, mother of pearl imitation pearls, and shell powder synthetic pearls are the most common fake pearls on the market today.
1.The visual method
The visual method is the most basic and straightforward way to observe and distinguish pearls by their color, shape, size, and luster.
Real pearls do not all have the same color, shape, or size. Pearl is the world’s only living organic gem.
It is a natural product. It cannot be cast in the same way that a machine mold can， Every pearl is identical to the next.
If every pearl is exactly the same size as two peas, it is very likely that it is a fake pearl.
Even if a real natural pearl is chosen, its size and color will never be exactly the same, whereas a fake pearl, on the other hand, can do this because it is manufactured by machine.
2.Determining the weight of a pearl
The manual method of distinguishing between genuine and fake pearls.
Natural pearls are difficult to make completely round and smooth.
If the surface of the pearls is smooth，you can assume they are fake pearls.
Another method is to assess the weight of pearls using the sensation of the hands to determine the true and false.
Natural pearls are heavier than pure glass imitation pearls. The weight of wax filled glass imitation pearls is roughly half that of natural pearls.
3.Using a magnifying glass
A magnifying glass has always been one of the most effective tools for telling the difference between genuine and fake pearls.
When viewed through a 10x magnifying glass, the surface of a natural pearl resembles a sand dune, with its surface shape formed by the growth texture and calcium crystals of a natural pearl.
The surface of artificial pearls, on the other hand, is uneven, similar to the surface of an eggshell. Simultaneously, there is the phenomenon of coating peeling off.
4.Observe the rebound height
Because of the differences in density, weight and elasticity between natural and man-made pearls, the height of rebound when they are dropped at the same height will be different.
The rebound height of natural pearls falling from a height of 60 cm onto a glass plate is about 35 cm.
5.Hydrochloric acid reaction method
The hardness of pearls is 2.5-4.5 and the relative density is 2.72-2.78.
Hydrochloric acid will react when dropped on the surface of natural pearls.
Artificial pearls, on the other hand, do not react with acid.
6.Use a knife to scrape the surface
Some powder will fall off the surface of natural pearls if you scratch it with a knife.
And if you scrape the surface of artificially coated pearls with a knife, some of the coating will come off.
7.Using ultraviolet light
Ultraviolet light also has its own unique role in identifying genuine and fake pearls.
When UV light hits a pearl, natural pearls produce a yellowish or whitish reflection.
Because natural pearls are caused by the secretions of shellfish, natural pearls contain a large amount of protein.
Fake pearls, on the other hand, do not have this reflection.
