Physical properties
Hardness: 2-2.5 (Amber), 8-8.5 (CZ); Color: Honey yellow/orange; Luster: Resinous to Adamantine; Crystal Structure: Amorphous (Amber), Cubic (CZ)
Formation & geological history
Amber is formed through the fossilization of tree resin over millions of years (typically 30-90 million years old), often found in sedimentary deposits.
Uses & applications
Used primarily in jewelry, decorative arts, and as a scientific medium for preserving prehistoric inclusions (insects/plants).
Geological facts
Amber is one of the few organic gemstones. It is known to build up a static charge when rubbed and can float in salt water.
Field identification & locations
Identify by its weight (very light) and warmth to the touch; amber is often paired with synthetic stones like CZ in commercial silver jewelry.
