Is a platinum ring better than gold?
A platinum ring is considered more expensive, refined, and unique. Such jewelry is made of pure metal.
The platinum content reaches 90 percent in the alloy. For wedding rings, it's original, and men like to have a platinum ring.
There are two types of white gold rings. The cheaper 14 carats and the more expensive 18 carats.
Rings of 14 carats in their composition have nickel-metal, which can cause allergies. It is nickel that makes the gold alloy white. The more expensive 18-carat rings in their design contain a platinum group metal - palladium. It is palladium that makes the color of gold white. This is a more noble alloy for wedding rings.
White gold rings are often covered with rhodium. Such rings shine more, and there are no scratches on them. Before choosing platinum or white gold ring, you need to read about the features of the platinum group metals. It is always exciting and valuable to tell your man and show your intelligence.
Along with gold, platinum is widely used in jewelry. The history of its application is fascinating. After Columbus discovered America, ships loaded with jewels sailed from a new continent to Europe: gold, silver, unique stones. But among these jewels, there was one previously unknown metal. Outwardly, it was similar to silver but heavier and denser. And not only silver but also gold. The metal was dubbed "platinum," which means a disparaging "silver" in Spanish for its resemblance to silver.
Platinum at first seemed to jewelers to be a metal of little use. Silver is soft, malleable, and platinum is brittle. It was impossible to flatten or melt it, and it was impossible to dissolve it in any acid. Meanwhile, in the mines of South America, platinum has always been found together with gold. Sometimes, when washing gold sands, platinum was obtained even more than gold. It was complicated to separate them because of their almost identical weight.
Counterfeiters were the first to find a use for platinum. In Spain, gold coins with an admixture of platinum began to spread very quickly. Such gold was called "rotten" or "Spanish." The ducats of the Spanish state fell in price very quickly, and in some countries, they stopped accepting them altogether. The royal order of 1743 was obliged to carefully look through all the extracted gold, platinum to separate and flood in rivers. Platinum has been banned for three years. The Spaniards attacked about 4 tons of it.
But it was not possible to completely ban platinum. It continued to arrive in Europe and finally found a use. In 1776, jewelry made of a previously unknown metal - platinum - appeared in the windows of jewelry stores in Paris, the world trendsetter. The advertising of the products was organized very skillfully. Equally cut diamonds in gold and platinum frames were displayed in the window. Gold gave the stones their usual yellowish hue, while platinum enhanced their whiteness. In platinum, the diamonds looked larger. At the same time, advertising began to report that platinum is a symbol of wealth, that this metal is unique and challenging to access, it is not easy to get it, and few people know the secret of its processing.
The popularity of platinum was growing every day. And in 1815, the London Stock Exchange registered an incredible fact: platinum began to cost much more than gold. Since then, platinum jewelry has quickly become fashionable.
Every day the popularity of platinum products increases. This metal has unique properties: resistance to aggressive chemical compounds, extraordinary plasticity, high melting point.
Platinum has a white-gray color similar to steel, practically insoluble in water and acids, except hot "royal vodka." It is plastic, highly polished, has high reflectivity, has low thermal and electrical conductivity, low specific heat capacity.
An alloy of platinum with 10% iridium is known because in 1870, it was selected by the International Committee of Weights and Measures in Paris as a material for the manufacture of a standard meter.
Palladium is a silver-white metal, ductile and malleable, quickly rolled into foil and stretched into a thin wire. In the air at average temperature, it does not oxidize. It is resistant to a humid environment. Palladium is inferior in its properties to all metals of the platinum group. It dissolves in nitric and hot sulfuric acids, as well as in "royal vodka." Palladium is not yet considered a generally accepted independent metal for the production of jewelry. Most often, it is an additive for obtaining white gold.
Rhodium -bluish-white metal resembling aluminum, hard and brittle. It has a high reflectivity. Chemically resistant. Under normal conditions, it does not oxidize in air and water. It is resistant to acids (except concentrated sulfuric acid) and "royal vodka." It is used as a decorative protective coating of a jewelry and as a coating of diamond frames to increase their luster and protect against tarnishing.
