Chapter 22: Minerals and Igneous Rocks

All Minerals are NOT Created Equal!



As a metal, gold is commonly prized for its long association with stature and wealth. Although these few pieces of shredded gold are not as prized as the Queen’s gold bars might be, gold as a precious metal is still one of the world’s most prized minerals. Because all minerals have unique properties that differentiate them from others, gold cannot be mistaken for diamond or even quartzite. Not only do the colours, hardness, lustre, streak and cleavage differ, but their very chemical compositions set them apart. In this way, two different minerals are most certainly not created equal. 



Still referred to, to this day, the Mohs Hardness scale lists diamonds as being the hardest mineral. These rings can cut!
