How to tell genuine Baltic amber from imitations?

In the jewellery market, it is not uncommon to find amber imitations made of plastic, synthetic resins or copal. For distributors and lovers of this stone, the ability to verify its authenticity is crucial. Although our workshop uses only certified raw materials, it is worth knowing the basic identification methods.

One of the best known and simplest tests is the saline test. Genuine amber floats on the surface of salt water (about 3 tablespoons of salt per glass of water), while most plastic imitations sink to the bottom. However, it should be remembered that copal (young resin) can also float, so this test does not provide absolute certainty.

Another method is the electrostatic test. When genuine amber is rubbed vigorously against a natural material, such as wool or silk, it becomes negatively charged and attracts tiny pieces of paper. Most modern plastic fakes do not exhibit these electrostatic properties.

The ultimate confirmation of authenticity lies in inclusions and examination under ultraviolet light. Under UV rays, real amber shows specific fluorescence in shades ranging from blue to yellow-green. For valuable and unique specimens, especially those with inclusions, it is always best to rely on certificates issued by accredited organisations, such as the International Amber Association.
