The mineral hardness scale was established by the German mineralogist Friedrich Mohs in the early 1800’s. He based the scale on ten common minerals ranging from talc, the softest mineral on the scale, to diamond, the hardest. Each mineral on the scale will scratch the mineral below it and will be scratched by the mineral above it.

Fingernails have a hardness of about 2.5. Steel knife blades rate a 6.5 and glass shows up on the scale at about 5.5. Metal files have a hardness of about 6.5. Quartz stands at 7 on the scale.

The topaz gemstone has a hardness of 8, which makes it quite suitable for use as gemstones in topaz gemstone earrings, topaz gemstone necklaces, topaz gemstone bracelets, and even in topaz gemstone rings.

Hardness	Material	Absolute Hardness
1	Talc (Mg3Si4O10(OH)2)	1
2	Gypsum (CaSO4·2H2O)	3
3	Calcite (CaCO3)	9
4	Fluorite (CaF2)	21
5	Apatite (Ca5(PO4)3(OH-,Cl-,F-))	48
6	Orthoclase (KAlSi3O8)	72
7	Quartz (SiO2)	100
8	Topaz (Al2SiO4(OH-,F-)2)	200
9	Corundum (Al2O3)	400
10	Diamond (C)	1500

Topaz Gemstone Necklaces have a long and storied tradition.

During the Middle Ages topaz was thought to heal both physical and mental disorders and prevent death.

The Greeks believed it had power to increase strength and to make its wearer invisible while the Romans believed it had power to improve eyesight.

The Egyptians wore it as an amulet to protect them from injury.

Yellow is the colour generally associated with the topaz, yet topaz is sometimes colorless, or may present almost any color, and beautiful specimens of other colors have sometimes been thought to be some other mineral, so thoroughly identified is this stone with the color yellow.

Whether worn as amulets or just beautiful accessories, topaz gemstone necklaces are as great a choice as ever!

There a a number of things to consider as you choose your Topaz Gemstone Rings and other jewelry. One of these is hardness of stone.

A mineral’s hardness is determined by scratching it with an object or another mineral of known hardness. Mineralogist Friedrick Mohs (1773-1839) developed a set of reference minerals ranging from hardness 1 (talc) to hardness 10 (diamond). Some everyday objects can also be used aas references: a fingernail (2.5), copper coin (3.5), glass (5.5), or a steel knife (6.5). Hardness is a destructive test, as it leaves a scratch. Minerals below a hardness of 7 are unsuitable for everyday wear as gemstone jewelry.

The topaz gemstone has a hardness of 8 according to Moh’s scale.
