I am no expert on Amber,but I do know that the difference
between Amber and Copal is in age of the material.The Amber is
much older and has had more time to petrify.The only
identification I know,having worked the two,is that Copal is
very brittle and unsuitable for lapidary work.There are several
good books on Amber that could give you a more gemoligical
answer.
