Ruthenium is a hard and brittle light gray multi-valence rare metal element, the element symbol is Ru, is a member of the platinum group of metals, very rare, the global annual production of Ruthenium is 12 to 20 tons, the content in the earth's crust is only one billion, is one of the rarest metals, and gold production is more than 3000 tons. Ruthenium has very stable properties and strong corrosion resistance. It can resist the corrosion of hydrochloric acid, sulfuric acid, nitric acid and aqua regia at normal temperature. Its alloy has superconductivity. It also has other unusual and unique properties that have applications in the electronics, chemical and solar industries.
Traditionally, wedding rings have been made of gold, most commonly 18 karat (75 percent pure) and 24 karat (99.9 percent or more).
There are many alternatives to gold, including silver, platinum, palladium, iridium, tungsten, cobalt and stainless steel.
Hardness, corrosion resistance, durability, purity, beauty and price are all factors to be considered.
But ruthenium, just as brittle and hard as tungsten, is also difficult to work with, so you are advised to keep the ring safe and remove it before any heavy work or weightlifting. If you press 300 pounds on a bench, pound a brick wall, or you drop it from a height onto a hard floor, there's no guarantee it won't break. This is your chance to wear a ring of such high purity made from one of the rarest metals in the universe. Wear it with pride and caution.
