Dominican Amber, genuine and natural stone.

Many ambers present in the market are treated with a process to improve their appearance. This is not necessary in Dominican amber.

The inclusions in the Dominican amber are natural, since the Dominican amber is naturally beautiful and does not need any treatment as in the case of baltic amber.

 

Some amber treated as for example the baltic amber have round and flat inclusions, irregularly distributed by their mass, called sequins, which are internal fractures produced during the treatment to improve the appearance.

The treatment is done by heating to produce aging and eliminate the turbidity, and to change the color. Clarifying, heating it in rapeseed oil, the transparency of Amber is produced and also special effects such as "sequins".

It is also heated to melt and produce larger pieces.

 

As already explained, these treatments are not made in the Dominican amber, which is of high quality and does not need any process to improve its appearance.


The blue colour is confined exclusively to the surface because does not result from pigmentation in which case colour would be reflected in any light, regardless of the colour of the background being used. Instead, blue is due to a fluorescence phenomenon which refract blue light.   

This phenomenon is best prized in natural light or direct sunlight, or white LED light, preferably on a dark background. Thus, the light passing  directly through amber produces the peculiarity blue glow which characterizes Dominican Blue Amber.

Authentic Dominican Blue Amber

Recently, optical absorption, fluorescence and time-resolved fluorescence measurements in Dominican ambers have been reported.

These studies show that the "blue" variety reveals an intense fluorescence emission in the visible wavelength region, between 430 and 530 nm, with spectral features typical of aromatic hydrocarbons.

On the contrary, the Dominican "red" and "yellow" amber varieties have a much weaker and featureless emission, although still do have a certain fluorescence. The process in blue amber is surprisingly similar to phosphor. Although there are several theories about the origin of Dominican blue amber, there is a great probability that it owes its existence to ingredients such as anthracene as a result of 'incomplete combustion' due to forest fires among the extinct species Hymenaea protera trees about 25 to 40 million years ago.

* Vittorio Bellani and Enrico Giulotto at the University of Pavia, Italy studied several amber specimens by means of optical absorption, fluorescence spectroscopy, and
time-resolved fluorescence measurements. The resulting spectral analysis revealed that the spectra of the hydrocarbons are very similar in shape to those of diluted solutions of anthracene, perylene, and tetracene, and suggest that the fluorescent hydrocarbon responsible for the blueness is most likely perylene.
