Fakes do not possess the properties of amber, but successfully imitating its appearance, occur very often. To distinguish natural amber in color, form and transparency. Amber is of three types: opaque (this includes foam and bone amber), translucent (in this category amber there are concentrations of voids, giving a cloud of turbidity) and completely transparent. Forge with equal success all three categories.

If natural amber is to RUB pure wool, it will get electrified. exactly and will attract pieces of thread, dust, paper. With fake the effect will be much weaker. Simulation can be defined with the help of saline solution, but this method is only suitable for loose amber. Stone put in a salt solution, the fake will sink, while amber rests on the surface. Determine the authenticity, by using the magnifying glass, the power needs to be at least tenfold. Wavy formation that appears when the sintering of the particles, are fake. Thus it is possible to distinguish amber from various types of polymers and plastics.

Much more difficult is to distinguish amber from Copal, with which they are similar in color and form. The Kopal call used in the manufacture of varnishes fossil resin. When heated, the smell of digging unpleasant, and amber highlights like the clove flavor. Copal melts more easily and is not electrified by friction. In essence he is an immature resin and its composition is identical to natural amber, but it is very soft, the dent it can leave sometimes even with a fingernail. If you put on a stone a drop of alcohol and the surface becomes sticky is dug. The Kopal stains from acetone, amber no. If digging is treated in an autoclave, it acquires all the properties of natural amber and to distinguish a fake is even more difficult.

Pressed amber is another common alternative to amber. The product is obtained by processing small pieces of amber with amber flour adding color. At a temperature of 200-250oC and high pressure amber melts and becomes a homogeneous mass, retaining virtually all of the properties of amber. The microscope experts note the changing shape of the bubbles and overall character structure, now resembling a mosaic or a patchwork quilt. This amber, in contrast to the natural, softened under the influence of ether - the surface becomes sticky. It is believed that after heating special natural sequence and polarity of the molecules is lost, and it is characterized by the ability to cure many diseases.

Look closely at amber. You should know that in fakes, as a rule, are present in abundance air bubbles, and the color of the product uniform throughout its length. Natural gem, especially if it is not subjected to heat treatment, has an interesting color transitions between shades.
2
Weigh the piece of amber. Amber is one of the lightest semi-precious stones. The weight of large amber beads may only be 50 g. Glass and plastic imitation much harder. Besides, it feels colder than natural stone.
3
RUB the piece of amber on cloth. Natural stone in this case becomes negatively charged and begins to attract finely cut paper or a hair. If the electrification happens, before you fake.
4
Attach to the surface of the stone a red-hot needle. If you felt a specific smell of rosin is a natural gem. The sharp smell of burning plastic will point you to the artificial origin of the "stone". Also be aware that when involved in a fire , the amber comes on for three seconds and continues to burn strong flame after it recovered from the fire.
5
Make a saline solution. To do this, dissolve in a glass of water 10 teaspoons of salt. Immerse amber in the liquid. Natural stone will float to the surface, the forgery will lie on the bottom of the glass. Be sure to rinse the gem in running water after this experiment, otherwise it produces a salt crust.
6
Cut a small strip of the products from behind or just in an inconspicuous place. It is recommended to do this with a sharp knife or razor. Natural stone will slightly crumble. Artificial likely to srazhatsya soft shavings.

If you see in amber is quite a modern fly can be assured of forging.

Advice 3: How to identify amber

How to identify amber
Instruction
1
Imitations of amber are usually made from Copal, plastic, celluloid, glass and synthetic resins. Often a fake put internal inclusion, simulating a fossil of an insect or a leaf of an ancient fern, which should increase the value of the stone.
2
To identify a fake note not the product (for example, in place of the holes of amber beads). Fake amber is easily crumbles and breaks off. If you heat the crumbs the product of artificial material at the tip of a knife, they will emit the unpleasant characteristic odor.
3
Another way to check the authenticity of amber is to put it in strong brine, where it needs to stay on the surface, while in pure water it sinks.
4
A professional with special equipment, will reveal the imitation is even easier – natural amber under UV light, emits blue light.
5
Young or "immature" amber called Kopal. Age digging is usually not millions of years, but only a few tens of thousands. Modern technologies allow to dig, identical to natural stone, resin trees.
6
In order to distinguish Copal from full amber in an inconspicuous area of the product, apply a drop of alcohol and apply to this place the finger. The sticky surface will give digging. The second method of detecting dig – apply for a couple of seconds a drop of acetone on the surface of the inspected material. If in this place there is a spot, we are dealing with Kopal. This method should be used with caution as prolonged exposure to acetone even natural amber can remain the spot (it is removed by polishing).
7
Keep in mind that counterfeiting of plastics should be distinguished from natural pressed amber. Only a small fraction of produced natural stone has large dimensions; a large part is a small pieces of stone, were treated by extrusion. Upon closer examination, this amber seems composed of small pieces, but it's still a natural material with inherent natural properties.
