Hardness : 7 ''Golden Crystal quartz'' is a variety of quartz and gets its name from its colours which range from whitish pale gold to dark orange golden colours with streaks of dark pink to red. Its vibrant colour conveys positive energy.
Hardness can be measured on the Mohs scale of hardness. This scale, with a range from 1 to 10, designates harder materials with higher numbers. Quartzite offers an approximate value of 7 on the Mohs scale while granite offers a hardness value of between 6 and on the Mohs scale.
What is quartz made of? Quartz is an igneous rock made out of molecules of silicon and oxygen atoms held together in a crystal pattern. All of the silica and oxygen that make quartz came originally from the insides of stars, and it shot out of the stars when the stars exploded as the silica formed part of a nebula, a dust cloud floating in space.

The Mohs scale of mineral hardness (/ m oʊ z /) is a qualitative ordinal scale characterizing scratch resistance of various minerals through the ability of harder material to scratch softer material. Created in 1812 by German geologist and mineralogist Friedrich Mohs, it is one of several definitions of hardness in materials science, some of which are more quantitative.
Mohs scale of mineral hardness – Wikipedia, the free encyclopedia. The Mohs scale of mineral hardness is based on the ability of one natural sample of matter to scratch another mineral. . osmium, quartz, rhenium, vanadium: »More detailed

Diopside is a monoclinic pyroxene mineral with composition MgCaSi 2 O forms complete solid solution series with hedenbergite (FeCaSi 2 O 6) and augite, and partial solid solutions with orthopyroxene and forms variably colored, but typically dull green crystals in the monoclinic prismatic class. It has two distinct prismatic cleavages at 87 and 93° typical of the pyroxene series.
Also known as indigo copper. Chalcopyrite is a major ore mineral of copper; crystallizes in the tetragonal crystal system, but crystals are generally small with diphenoidal faces resembling the tetredron; usually massive with a metallic luster and brassyellow color; hardness is –4 on Mohs scale, and specific gravity is –
