But to know the characteristics of what is the most rare and noble material, platinum, could lead to making a different choice.

For this, for example, it is very appreciated in jewelry to containing precious stones: the jaws platinum are more secure than those in gold. Also, the color goes well with the purity of diamonds. It’s often used in alloys with other metals, such as iridium, osmium, palladium, rhodium and ruthenium, but in this case should be reported. If you buy a platinum jewel beware that has the symbol ‘Plat’: means that platinum is a purity of 95%.
History. Platinum was already known by the ancient Egyptians: historians have established that a priestess commissioned a craftsman platinum hieroglyphics on her sarcophagus.

And some of the most famous diamonds in the world were placed in a platinum structure, such as the Hope diamond.
