The Difference Between White Gold and Platinum

     

 

Metal

 

Platinum is an ideal metal for use in jewelry. In 1790 French king Louis XVI called platinum “the only metal fit for a king”. Although platinum was discovered relatively recently, it quickly gained the status of prestigious metal for expensive jewelry. It is also widely used in industry and for medical purposes. Platinum was already known in Antiquity, but for the first time in pure form it received only in 1735, because unlike gold it the isolation and identification require substantial effort. The platinum grains are usually too small to be seen without a microscope.

Platinum occurs in the form of scattered granules in sulfide ores contained in igneous rocks. There are also several small alluvial deposits, in which platinum is more common in the form of grains than in the form of large nuggets. Extraction and isolation of platinum — a time-consuming process: to get 30 g of pure metal need to process 10 tons of ore, which takes at least 5 months. Platinum is a refractory metal, and suitable technology of its selection was developed only in the 1920s, and this means that the pure platinum became available. Most platinum jewelry is made of alloy of copper and platinum is 90-95% platinum, the rest is copper.

For making jewelry platinum has been used for thousands of years. In Ancient Egypt, platinum was ornamented sarcophagi. The Spanish conquistadors engaged in South America looking for gold, and found platinum. Believing that they are dealing with “unripe silver,” they called previously unknown metal platina, meaning “little silver” and threw it back into the river. Malleable platinum appeared only in 1789, and soon this rare and expensive metal interested in all the European monarchs.

In 1824, a large Deposit of platinum was discovered in Russia, in the Urals. The price of platinum reached a peak in 1912, when it appeared a cheaper substitute for white gold. In 1924, Hans Merensky (1871-1952), opened the world’s largest Deposit of platinum in the Transvaal in South Africa. In 1939, the U.S. government declared platinum a strategic commodity, and its use in jewelry was banned until the end of the Second world war.

The jewelry industry consumes only 40% of all mined platinum. About the same is spent for the production of catalysts, and the rest is used in industry, particularly in computers, LCD monitors, and drugs to treat cancer. Glitter of platinum and its high specific weight makes it an excellent material for fastening the precious stones. Platinum is a hard metal that does not cause allergies. Over time replaced its bright Shine comes light patina — patina.

The difference between platinum white gold. Jewelry platinum is a precious metal natural white color, while white gold “bleached” due to the impurities added to the alloy (see the composition of white gold), or the procedure Radiomania. Platinum is considered more precious metal, and therefore its cost is higher. Platinum products are made from virtually pure alloy (95% platinum per thousand units of alloy or 950 test). White gold highest of 750 contains 75% pure gold at the same a thousand pieces of alloy. This is the most important factor influencing the difference in the price of platinum and gold products. Other criteria is the rarity of the platinum distribution in nature and complexity in production and we should not forget that the production of platinum jewelry requires a higher level of skill because of the physical properties of the metal.

Platinum is heavier than gold due to its density. So, if you take two the same wedding ring, platinum 11.4% will weigh more than a ring of white gold. Due to the purity of the platinum products do not cause allergies and is ideal for people with sensitive skin. Platinum is the most reliable material in all faceted gemstones: white gold may be damaged or deformed, because it is inferior to platinum in hardness. And, of course, referring to the strength of the metal, platinum jewelry scratch less gold and therefore more durable.
