Amber, once thought to be ancient petrified sunlight

Amber is the hardened sap of ancient trees. The majority of amber is younger than 90 million years old, but a 320-million-year-old piece of amber in an Illinois coal mine. This organic substance is most well-known for the incredible inclusions that can be found within it. People have been making amber jewelry since 10,000 BCE, which could make it the first gem material ever used .Amber has been found throughout the world, but the largest deposits occur along the shores of the Baltic Sea. Amber occurs as irregular nodules, rods, or drop like shapes in all shades of transparent or opaque colors:  yellow, orange, brown, and rarely, red. Milky-white opaque varieties are called bone amber. Green and Blue amber are rare and can occur int the Dominican Republic and Indonesia.
