Amber drops are the overdose of resins that broke away from the streams, which used to flow through icicles and trunk. They could be different size; their conservation is dissimilar and their structure is usually deformed. Drops flattened by falling are most frequently found (about 30%).
Regular shape drops are very rare – they could be formed when resins flowed from slits of wood or when they fell into the water.
Drops weight from 5,4 - 10 g.
