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 inclusions which include insects and plants. I am not an expert in paleo-insects, so I cannot identify what exact species is present in some of these pieces, but I do see what appears to be small ants or flie larvae. There are also two large prominent plant inclusions that appear to be leaves.
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.
