What kinds of amber are there? Who can tell me which amber is in the picture below?

Hope. Haiper on the market is basically optimized manually, so don't worry, because this optimization process is recognized by the European jewelry industry. But personally, I think this kind of amber has no collection value and can only be used as a handicraft. If you want to collect, you should pay attention to the mines, especially those in Fushun, China, so as to have real collection value.
