Gypsum is a very common mineral in sedimentary environments. It is found as massive material ( Alabaster ), clear crystals ( Selenite ) and parallel fibrous variety ( Satin spar ). Gypsum is very soft and very difficult to facet because of its perfect cleavage, therefore faceted stones are quite rare.
Hardness is one of the better properties of minerals to use for identifying a mineral. Hardness is a measure of the mineral's resistance to scratching. The Mohs scale is a set of 10 minerals whose hardness is known. The softest mineral, talc, has a Mohs scale rating of one. Diamond is the hardest mineral and has a rating of ten.

The key difference between gypsum and limestone is that the calcium sulfate is the main constituent in gypsum whereas calcium carbonate is the main constituent of limestone.. Limestone and gypsum are minerals that form from calcium salts; limestone contains calcium carbonate while gypsum contains CaSO 4 ·2H 2 O. However, their properties and usages are different from each other.

MINERALOGY, PROPERTIES, OCCURRENCE: The selenite variety of gypsum [hydrous calcium sulfate, CaSO 4 ·2H 2 O] crystallizes in the monoclinic system as prismatic or bladed crystals with distinct rhombic form, and as arrowhead-shaped twins with beveled edges. Pure selenite is colorless or white, but impurities create a range of pale grays, yellows, reds, and browns.
• Identify several common minerals based on their physical properties LAB 3 Minerals INTRODUCTION Minerals are the foundation of our planet and our society (we use minerals every day!). Minerals are used to make items like cars (Figure 1), smartphones, building materials, and pencils. They are also essential components of many foods we eat.

102 Gypsum is the most common sulfate mineral and has been known since the time of the 103 Greeks (e.g. Bromehead 1943). Gypsum occurs as clear crystals called selenite or as 104 massive material called alabaster. Anhydrite was named after the Greek word for "without 105 water" (Ludwig 1804) and can be vitreous, greasy and pearly.
Properties of Gypsum Plaster. Gypsum forms as mineral deposits when sea water evaporates. These deposits are composed of calcium sulphate and water.
