Uses & applications
Used primarily in jewelry, decorative carvings, and occasionally for scientific preservation of ancient insects and plant inclusions.
Geological facts
Amber floats in saltwater and can produce static electricity when rubbed with cloth. Famous deposits are found in the Baltic region and the Dominican Republic.
Field identification & locations
