This is a polished specimen of fossil Dominican Amber. This amber comes from mines in the Dominican Republic and is approx. 25 million years old.
This piece has multiple small insect inclusions. I am not an expert in paleo-insects, so I cannot identify what exact species is present, but I do see what appears to be small ants or flie larvae.
This piece would be ideal for study with a loupe or microscope. It would also make a good pendant or ring in the right mounting.
