different amber dice
more informations in the Wikipedia article amber
Amber is basically a petrified resin.
It can occur in different colors. Mostly yellow, clear to opaque. But there are also ambers with white inclusions or green shimmer.
Best known is the origin of amber from the Baltic Sea region. However, there are different occurrences worldwide.
pressed amber with fly
Press amber is not like some think, a plastic, but it consists of remnants of real amber.
Around 1870 this method was developed in Königsberg. Small pieces of waste are pressed together under pressure and heated to a new piece.
Bakelite later replaced the press amber because it was cheaper to manufacture.
Of course you can also make dice from amber.
The price makes these dice more of a gem than a utility object.
