FOSSIL AMMONITES SAWN 1
Ammonites in the broad sense, or Ammonoidea, are an extinct subclass of cephalopod molluscs. They appear in the fossil record during the Devonian and disappear shortly after the Cretaceous-Paleocene crisis. They were characterized by a univalve shell more or less coiled of which only the last lodge was occupied by the animal, the other lodges being used to control its flotation; the siphon connecting them is in the external (ventral) position, along the wall, whereas it is axial in the nautiluses. Their fossil shells are excellent chronological markers. Their size ranges from a few millimetres to more than 2 meters in diameter.

ROUGH ST AAA CORUNDUM BLUE-ISH
Corundum is best known for its gem varieties, Ruby and Sapphire. Ruby and Sapphire are scientifically the same mineral, but just differ in color. Ruby is the red variety, and Sapphire is the variety that encompasses all other colors, although the most popular and valued color of Sapphire is blue. Sapphire is also only used to describe the gem variety; otherwise it is simply called Corundum.
Corundum is a very hard, tough, and stable mineral. For all practical purposes, it is the hardest mineral after Diamond, making it the second hardest mineral. It is also unaffected by acids and most environments. Translucent brown Corundum and Emery are the most common forms of Corundum. These are fairly common forms, and due to their great hardness and prevalence are the most favorable abrasives. The industrial term “emery” describing Corundum abrasives is derived from the variety Emery which is mined specifically for its use as an abrasive. Erosion may cause Emery to crumble and form sand, which are sometimes called “black sands.”
Chemical Formula Al2O3

ROUGH ST AAA QUARTZ AMETHYST CLUSTERS
Amethyst is a well known mineral and gemstone. It is the purple variety of the mineral Quartz, and its most valuable and prized variety. Its name derives from the Greek “amethystos”, which means “not drunken”, as Amethyst in antiquity was thought to ward off drunkenness. The color of some Amethyst specimens from certain localities slowly fade upon prolonged exposure to light. When used as a gemstone, Amethyst is often heat treated to deepen the color, or to transform it into Citrine.
Chemical Formula SiO2
Composition Silicon dioxide. Its purple coloring is usually caused by impurities of iron or manganese compounds.
Color Light to dark purple. Sometimes banded with purple and whitish lines. May also be mixed together with Citrine.
Streak White
Hardness 7
