During the process of fossilization, a variety of flora and fauna tend to remain trapped in the amber resin and eventually become an integral part of the final gem i.e. amber. Over the centuries fauna like larvae, caterpillars, bees, flies, butter flies, spiders and even land snails have been discovered in amber.
Flora like wood fragments, leaves, flowers, other plant parts and ferns are also found in the gem. The more unique the fossils in amber, the higher its value. Other trapped flora and fauna, dust, small pyrite crystals and other minerals may also be found in amber.
