A car, a telephone, even a refrigerator - all this equipment is made of iron, the production of which is a very complex process. The main raw materials for obtaining this valuable material are minerals, which contain particles of the necessary metal. In simple words, it is a rock containing alloys. There is a huge amount of this resource in the world, the methods of processing it and obtaining minerals from it can be very diverse, but it all starts in the mines. What mining ore is, how it is mined and processed will be discussed in this article.
Gemstock collection from Gemstock
In our work, we prefer not to divide stones into precious and semi-precious, because the trends of the modern world market dictate a completely different approach. A precious stone is a type of natural mineral for which there is a constant annual increase in value and demand. At the same time, deposits of such stones are not large or numerous, which creates a shortage of high-quality jewelry stones on the market. Sometimes the political situation in mining countries also affects the pace of deposit development and the volume of stones supplied, and this, in turn, also affects pricing. Along with the generally accepted big three colored stones (sapphires, rubies, emeralds), the last decade has also brought forward new favorites, such rapidly growing in price stones as Paraiba tourmaline, red spinel and spinel of other rare colors (pink, blue, light blue, violet), tsavorites ( tsavorites), spessartines, rubellites, etc. Many of the listed gems can easily compete in cost per carat with diamonds, and in some cases even outperform them.
Minerals for collection - lists
I am publishing lists of minerals, ore and non-metallic rocks - for collection, options for collecting samples. Such collections are great to make and collect with schoolchildren of all ages. In general, all children love to sort through stones. And adults too. 
This information will help you position your mineral collection specimens correctly. And it is better for those who collect partworks with stones from De Agostini to understand their collection. As you can see, the list of stones is large, so even if you have collected all of DeAgostini’s issues, you can continue to collect them yourself.
