Amber is often confused with the digging

It is very difficult to understand a piece of amber origin. This is because the market is filled with a few imitation amber, to confuse the buyer.

One of his numerous imitations called Amberdan. It has properties very similar to natural stone. The road to originality test, when the stone is heated and has a certain smell. If you smell a mixture of plastic and amber fragrance, it suggests that natural resin mixed with a polymer binder was.

Amber is often confused with the digging. These two stones are composed of materials very similar to the history of almost identical, and it is difficult to determine the origin of amber. The main difference is that while digging only some 100.000 years, Amber, a few million years.

Another simulation, freshwater pearl jewelry, which is on the market, up or pressed amber "ambroid. It is created by the merger of small pieces of stone in the heat. It can be distinguished from the original stone examine under a microscope.

old techniques to identify this little gem is still useful. If rubbed vigorously on a piece of cotton wool, it creates a static charge, which is sufficient to obtain a small piece of ash. If the stone is hot enough, it tends to smell characteristic. These techniques are made of a plastic imitation of the individual, but does not differ from Kopal.

To distinguish this gem dug hard. They have the same refractive index, density, and most other features. However, as a rule, whiter Copal fluorescence under UV light yellow color. Thus, it is called the view that we need to make after consideration of a sufficient number of samples The main difference between this recognition.

If you are unable to distinguish on the basis of fluorescence, we shall resort to the chemical. On an inconspicuous area of stone, a drop of acetone. Let stand for three seconds, then wipe dry. Kopal damage the surface with acetone, and Bernstein show virtually no change in exposure to short.

Another simple method, which differs from its plastic imitation stones with the decision of density. Water to a boil and dissolve as much salt as you can create a practical test of liquid to add. Most simulations will sink in that decision. This is because some plastics with a density as low as 1.05 and may be much smaller than the amber, if they have air bubbles. So if your sample falls, you can be sure that it is not realistic. If it floats, you must determine if it is plastic or yellow.

There is another destructive tests on real Amber to separate from fiction. This should be done with great caution. The best part is that it can be done almost invisibly. Find a place on the rock where the sign is as unobtrusive as possible. This could be on the verge, pearl strand, below or on the surface is scratched. Then, the heat of the red tip of the needle until it lights up. Press release in the correct position, enough to make a small cloud of smoke. Now, the smell of smoke. If it is real amber, incense fine. It's plastic, chemicals, and if it is offensive. This is another reason to check on a small scale to make it possible!

Another test opening fake identification insect inclusions in the stone. If this stone, which has a representation of, say, stealing a modern house that could easily be that the stone is a fake. This is because the house does not fly there for millions of years, which means that the images were combined into a stone and it is not genuine.

With these tips and techniques so that it will be easier for you to identify and find the real jewels of amber in the wrong.
