• Yellow, orange and brown are the most common colors for amber, though rare blue amber is found in the Dominican Republic.
• The resin produced by most plants is composed mainly of terpenes and derivatives. The most common terpenes in resin are the bicyclic terpenes alpha-pinene, beta-pinene, delta-3 carene and sabinene.
• Typical rosin is a transparent or translucent mass, with a vitreous fracture and a faintly yellow or brown colour, non-odorous or having only a slight turpentine odor and taste.
• Baltic amber was called Freyas tears by the Norse and the tears of the Heliades by the ancient Greeks.
• Subfossil copal can be distinguished from genuine fossil amber because it becomes tacky when a drop of a solvent such as acetone or chloroform is placed on it.
• The monocyclic terpenes limonene and terpinolene and smaller amounts of the tricyclic sesquiterpenes, longifolene, caryophyllene and delta-cadinene.
