Since the early 1900's, white golds popularity has soared. The trend merging from platinum to white gold happened because although platinum was a popular choice, alot of people found it over priced and could simply not afford it due to its rarity.
As the second world war progressed, platinum was banned from use by the government for any non-military functions. Due to the already existing rarity for platinum, and then a ban, this made the demand for white gold sky-rocket.
White gold is not a pure form of gold. To get this material you have to add an alloy. The common alloys used in this process are nickel, palladium and silver. One this process is completed, the white gold is often applied an electroplated rhodium coating to give it an extra clean white finish. This also helps prevents any wear and tear, and to cap any allergies that some people may have.
Throughout the whole of this process, the white gold maintains many of its great benefits. Because of the added alloys, it gains strength, and has a rejuvenated wear-tear factor and in comparison to the traditional white gold it is undoubtedly stronger.
In recent times the usual alloy used to make white gold has changed from nickel, to the new replacement that is palladium. The main reason for this is because around 12-15% of the population have an allergic reaction to nickel, which causes rash and skin irritation. Due to this high percentage, law now states that any jewelry which contains nickel, now has to be labeled "nickel-containing."
