Featured Red Baltic Amber - a few words about modification

Written by 

Juicy red colors of amber have not been delighting with its clarity and saturated color since today. Some people says that it looks like rubies, other that garnets one thing is certain: jewelry with cherry amber looks very elegant. But why are they red? You will find the answer in this article!


The richness of the color varieties and the degrees of transparency of natural succinite make each of the stones different and unique a mysterious amber with inclusions, contaminated with organic matter, or mosaic with pictures that resemble landscapes.

However, in Poland there is still a myth about the fact that amber is not a stone for young people, that jewelry with "Baltic Gold" can not be fashionable and modern. Fortunately, eminent Polish amber artists are refuting this myth with their unique modernist projects.

Producers to attract clientele with an amber make the nuggets more attractive by changing their color or the degree of transparency. Modifications are a response to the needs of the jewelry market. It is worth noting that they do not lower the value of amber, they only make it more attractive to recipients. The nuggets are visually prettier - more clear, with trolls or in intense colors not found in nature.

The most popular colored versions of amber resulting from the modification are red and cherry colors. The change in the color of succinite caused by human influence leads to the formation of amber known as "dyed".

The modification allowing to obtain a red amber color takes place in an autoclave - in a high temperature (up to 250 ° C) and pressure (25-40 atmospheres) conditions and in the presence of oxygen and mixed proportions of inert gases (nitrogen, noble gases), which are process inhibitors [1]. The change in color occurs due to the conditions prevailing in the autoclave on the surface of natural amber. If the modified body was previously pressed (reconstructed), then the change of color takes place in the entire volume of amber [1].

Amber beautifying treatments sometimes change its properties to a small extent (eg, loosing the smell after rubbing or their luminescence), however, it is still Baltic Amber [2].

The leading producer of jewelry with red amber is Progres run by Mr. Janusz Pawlik (company from Gdańsk, whose collections are available in Boruni Gallery on Grodzka Street 60 and at the Amber Museum on St. Jana Street 2.
