Blue Amber Info

Dominican blue amber – is mined through a foxhole dug with all the tools are available. Machetes at the beginning, some short-handled picks, and hammers can participate over time.

The pit itself goes as deep as possible or safe, sometimes vertical, sometimes horizontal.

There are little to no safety measures. Candles are the only source of light.  

The holes are located on top of the mountain and deep within the mountains, and this allows the temperature is cool. Obviously, after many hours of work, the air becomes unhealthy.

Humidity inside the mines is at 100%.

During rain, the mines are forced to close because the walls may crumble.

Dominican Amber, genuine and natural stone.

 

Blue amber is the fossil resin of the Hamenaea Protera tree, a leguminous 25 to 40 million years ago on the island of Quisqueya (now the Dominican Republic) and extinct for millions of years.

Amber is extremely important to modern science because it provides the only truly worthy window into a past when exotic insects and other strange creatures roamed an ancient world, most of which have been extinct now for millions of years. 

 

Many ambers present in the market are treated with a process to improve their appearance. This is not necessary for 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 the baltic amber has 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 color is confined exclusively to the surface because does not result from pigmentation in which case color would be reflected in any light, regardless of the color of the background being used. Instead, blue is due to a fluorescence phenomenon which refracts 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.

 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 the 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 protea 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.
