GREEN_AMBER
GREEN_AMBERShort answer
Green material sold by amber dealers under names such as “natural green Caribbean amber” or “very rare Baltic amber”. Gemmological study records it as copal treated with heat and pressure; the qualifier “natural” is not supported by the source.

Before heating, all copal samples reacted to alcohol by losing their polish luster. Their surfaces became sticky and showed a fingerprint after being pressed with a fingertip.
