The extreme hardness and density of tungsten has given rise to modern jewelers to use this largely unusual metal in the manufacture of various jewelry. With a small addition of tungsten to the melt, its carbidization occurs and the refractory metal acquires a new property - malleability.
Jewelry made from tungsten is ten times stronger than similar items made from 18-karat gold and four times stronger than the "space metal" - titanium. Tungsten products are practically impossible to destroy under normal conditions. The hardness of tungsten is comparable to that of diamond, so a tungsten ring can only be scratched with a diamond.
If you have seen a movie about the hapless Hobbits "The Lord of the Rings", then probably the following fact will cause a smile: tungsten cannot be melted in basalt lava formed during a volcanic eruption, since its melting temperature is twice the melting point of basalt and is 2780 degrees Celsius.
On Earth, rarely, but there are people with an allergy to gold or silver. No one is allergic to tungsten products.
