MINERALS 



A collection of genuine minerals and 

 semi-precious stones so complete 

 you'd expect to find it in a museum. 



M 



ANY THOUSANDS OF YEARS AGO, when 

 man first walked the Earth, it was very 

 useful for him to understand the differences 

 between the minerals that nature offered. 

 There were hard materials from which he 

 fashioned his tools and hunting weapons. And 

 others, which were softer, could be ground to 

 make pigments and he used those for his cave 

 paintings. 



Thousands of years later, less common min- 

 erals were sought after for making decorative 

 items like jewelry as was the case with gold 

 and silver. 



Then, later still, someone discovered that, 

 by mixing metals like copper with tin, you 

 could create an alloy which was even harder - 

 and more useful - bronze. 



Now, you can acquire many of Earth's 

 fascinating treasures - Minerals of the Earth 

 -in a collection so complete that you'd only 

 expect to find it in a museum. 



Collected for you by experts 



Minerals of the Earth have been collected from 

 important geological sites on five continents. 

 Delicately colored Rose Quartz found in Brazil 

 and Madagascar. Clusters of Amethyst crystals 

 (geodes) from Uruguay. Iron Pyrites, with their 

 metallic luster, from Europe. Each specimen 

 hand picked for your collection. 



Each specimen comes with a colorful fact 

 sheet containing scientific data about its 

 formation, origins and uses. 

 To house these fact sheets, an attractive 

 binder is provided free for subscribers.
