Tungsten is not man made but comes from nature.Tungsten is one of the main elements we have used in the development of our civilization.In 1922 the Germans developed tungsten carbide as the material used in making better cutting tool bits for precision milling and for the cutting of steel parts.
Tungsten has the highest metlting point of all the elements.It melts at 3,420 degrees centigrade or 6,700 degrees fahrenheit and boils at 5,700 degrees centigrade or 10,300 degrees fahrenheit.What this means in layman terms is that on the surface of the sun, tungsten would become liquid, but if you dropped a piece of tungsten from outer space, it would enter the earth's atmosphere glowing to red and land on the earth in one solid piece.
In order to manufacture a perfectly crafted piece of tungsten magnum jewelry, it takes the skill and knowledge that only a handful of companies have mastered.It cannot be carved from a wax or simply machined from metal tubing.To make a ring that is virtually indestructible, tungsten is processed with carbon and ground into powder.The mixed metal powder is then compressed into high pressure molds, at extremely high temperatures, to form a ring (a new mold needs to be made for each finger size).The ring is then fired in an oxygen-free oven at an astounding 2400 degrees.The ring now has to be ground, cut and shaped using very expensive diamond tooling.This process is similar to the one used in cutting and polishing of rough diamonds.The result is a solid metal of extraordinary hardness and durability.
