According to what I could glean from a Google Search, "green amber"
(the one frequently seen on the market)has been treated by heating
the back side of the cab. True green amber does exist, however, it is
not what is commonly seen in the market place. It is recognized by
the International Amber Association as an acceptable treatment much
like the heat treating, etc. done on numerous
I found numerous references when I did a 'net search. This site was
the most succinct. (little amber humor, Baltic amber is referred to
as succinite): http://www.amberjewelry.com/Amber_Reading_Room_p1.htm
While on the subject, I'm looking for larger pieces of raw amber for
my "Viking hobby". I would like it to be Baltic amber, don't care
about the color , don't need it to be "buggy", just solid material
that I can carve. Any help would be appreciated.
