One hundred years ago, gold was produced for the first time when it was looking for an equivalent for the expensive Platinum. There are white gold in the most diverse compositions, since the title is not protected. Often, pieces of jewelry as white gold be sold, which bright were dyed in reality only through a surface treatment, which again takes time.
White Gold is not so equal to white gold. What you should know as a buyer of this precious metal, the following information articles:
White gold – the development of a replacement for Platinum
The history of white gold is only comparatively short compared to those of other precious metals. 1912 developed an alloy of gold, that Platinum very came close in their grey white shiny color in Pforzheim, Germany. There was the need for a cheaper alternative to the Platinum expensive due to its rarity. Various experiments aimed to get a precious metal Platinum confusingly resembling in its colour – a precious metal that is popular then and now of very popular, because it highlights the sparkle of diamonds very well. The classic engagement ring, for example, a Diamond Solitaire ring is traditionally made of Platinum. Learn more about the precious metal Platinum you way, in our blog article about Platinum.
The result of the research was an alloy of gold, where the gold was amended by Feingold by certain colour nuance shiny alloy partner to a bright metallic white. You came also the advantage that it was softer than Platinum and therefore to make from their lighter pieces of jewellery made. Against silver white gold distinguished this way, that’s not oxidized and thus not unattractive dark runs over the course of time.
The popularity of white gold has increased in the hundred years of its existence constantly and it has established itself as one of the most sought after precious metals along with yellow gold and Platinum. However, white gold is still not a clearly defined term and there exist no precise rules which alloys must bear this name so far.
The name White Gold alloys of very varying quality
White Gold is not itself to a protected designation, so many different gold alloys on the market are. Alloy partners are silver, zinc and manganese that weak entfärbend Act, or the heavily entfärbenden metals nickel, Palladium, Platinum, iron or chrome in question. The majority of these components has proved over the years not suitable; with silver, a Platinum-like hue can be made difficult, manganese white gold is negatively striking by its yellowish glow, nickel is incompatible for many, Platinum white gold is too dark and chrome white gold is not well formed.
Please note that it’s in under the name White Gold has to do traded jewellery very often not with white gold in the strict sense, but the bright metallic colour is produced only by a rhodium plating – a chemical coating -. The downside of it is that this outer layer slowly wears off and that material over time is revealed below. Since there is no relevant legal regulations, this “fake” white gold may be referred to and sold as such. You should enquire so definitely whether a rhodium plating is present or not.
White Gold – decoloration of Feingold by palladium
Long time, nickel was used by default to obtain a white colouring of yellow gold. The metal was very popular, since it works more entfärbend compared to silver. After however in the 1990s in Germany was, started to introduce stricter guidelines regarding the use of nickel in jewelry, you had to look for alternatives. The disadvantage of nickel is that many people are allergic to this metal. In the year 2000, the EU also dealt with the subject of the nickel and adopted a directive for all Member States.
Looking for an alternative to nickel the best results were achieved when Palladium has been used as an alloy partner in white gold. This fine gold-Palladium alloys contain usually silver and copper shares.
Try a quality backup for white gold – white gold task force
Due to the visible for the consumer variety of different white gold alloys, which was by the MJSA (Manufacturing Jewelers and suppliers of America) in collaboration with the World Gold Council in 2003 in New York City White Gold task force founded. She classified white gold in three grades: premium, standard , and Off-white. It is based on the ASTM yellowness index, which is measured using a densitometer, a device for determining the color density.
White Gold alloys which have a beautiful metallic shimmering colours and therefore require no surface treatment in the form of a rhodium plating – yellowness index located here under 19 receive the title Premium White .
Alloys, the yellowness index moving between 19 and 24.5 fall under the category of Standard White .
The lowest class of white gold with a yellowness index from 24.5 to 32 is Off-white and is provided with a rhodium plating to cover the unfavourable hue.
