Amber is any natural fossilized tree resin dating back to the Carboniferous, roughly 320 million years. Since around 3000 BCE it has been considered a precious material, used for adornment, fragrance, medicine and trade. Rarely, an insect or plant matter can be seen trapped inside the amber, and these pieces are highly sought after by collectors. Amber is commonly found along the shores of the Baltic Sea in northwestern Europe, the Dominican Republic, and Chiapas, Mexico.
Ordovician period – approximately 490- 445 million years old. Orthoceras was an uncoiled or “straight” Ammonite- and extinct relative of the well-known Chambered Nautilus. The soft-tissue creature would have lived in the last open segment on the wide end of the shell. As the body outgrew the segment, a dividing wall, called the septa, grew to separate the old home segment from the new. A small tube, known as the siphuncle, runs the entire length of the shell and was used for propulsion and buoyancy. These fossils are found in the Sahara Desert of Morocco.
Chalcedony is a variety of microcrystalline quartz that forms in the cavities and cracks of pre-existing rock. While white in its pure state, most chalcedonies contain trace elements and other mineral inclusions that give them a range of colors and patterns. Chalcedony that shows distinct banding, for example, is called agate. Other forms of chalcedony include chrysoprase, bloodstone, and jasper. Fine chalcedonies are found worldwide, including the U.S.A., Brazil, and India. Chalcedony is a nurturing stone that promotes peace and harmony.
