Mohs Hardness Scale
any mineral with a greater hardness than another mineral will scratch a softer mineral
Gem
valuable minerals that are prized for their rariety and beauty
Fracture
minerals that break with rough or jagged edges


uneven
conchoidal
hackly
splintery
Cleavage
minerals break along planes where atomic bonds are weak; formed by number of cleaved planes

perfect
distinct
indistinct
absent
Transparency
a function of the way light interacts with the surface of a substance.

transparent
transluscent
opaque
Streak
color the mineral is when broken down to powder; rarely changes even if the color of the mineral changes; one of the main tests used to distinguish between minerals; does not alwalys match with color
Color
Color is the first thing someone notices when they view a mineral. Color is also one of the big reasons that attract people to minerals. Generally speaking, color is not a good property to be used in the identification of minerals. It is usually the first property to confuse a novice collector into makingone of the most noticible characteristics of a mineral; sometimes caused by trace elements; one of the least reliable clues to the minerals identity
Specific Gravity
reflects atomic weight and structure of a mineral; ratio of the weight of a substance to the weight of an euql volume of water at 4 Celcuis

light
average
heavy
very heavy
Luster
the way a mineral reflects light from a surface


Adamantine - very gemmy crystals
Dull - just a non-reflective surface of any kind
Earthy - the look of dirt or dried mud
Fibrous - the look of fibers
Greasy - the look of grease
Gumdrop - the look a sucked on hard candy
Metallic - the look of metals
Pearly - the look of a pearl
Pitchy - the look of tar
Resinous - the look of resins such as dried glue or chewing gum
Silky - the look of silk, similar to fibrous but more compact
Submetallic - a poor metallic luster, opaque but reflecting little light
Vitreous - the most common luster, it simply means the look of glass
Waxy - the look of wax
Hardness
the measure of how easily a mineral can be scratched; measured with the mohs hardness scale

1 - Talc
2 - Gypsum
3 - Calcite
4 - Fluorite
5 - Apatite
6 - Orthoclase
7 - Quartz
8 - Topaz
9 - Corundum
10 - Diamond
Ore
a mineral that conatains a substance that can be mined for profit
Mineral Characteristics/ Mineral Identification
criteria defining if a substance is a mineral
Crystal Structure
geometic repeating structure of the crystals in a mineral

monoclinic
cubic
tetragonal
orthorhombic
triclinic
trigonal
hexagonal
