We are fascinated by gold and its derivations. The jewels in this material are exclusive and mesmerize anyone for its beauty and shine. Generally, when we think of gold we visualize the intense and real yellow color of the metal, but today there are variations of gold in terms of color, such as rose gold, red gold, blue gold, black gold and white gold.
What is white gold?
White gold is a mix of yellow gold with other metals. Pure yellow gold is too inconsistent and for jewelry it is usually mixed in a proportion usually ranging from 10 kt (10 parts of gold and 14 parts of other metals) to 18 kt (18 parts of gold and just 6 parts of other metals).
To simplify to the extreme, if gold is mixed with palladium or platinum it acquires an almost white tone. But if it’s mixed with copper or silver, it keeps its yellow color. Palladium is a new element discovered on 1803 and it’s a pure periodic elements, as silver or gold. On the other hand, fingers are different. Gold can be mixed also with with the expensive and hard to work platinum to obtain a white tone gold.
How to identify white gold?
It’s extremely difficult to differentiate with the naked eye an alloy of white gold from another gold alloy. In fact, the latter are often superficially treated with rhodium and in fact their color is slightly modified, they can take on the appearance of other white metals, such as silver, platinum, palladium, and even metal. It is therefore necessary to investigate thoroughly.
A more in-depth laboratory analysis is necessary to accurately determine the composition of an alloy.
It should be mentioned that the regulation on white gold doesn’t take into account the quantity of other materials, but only the weight in gold.
In order to allow consumers who don’t have the necessary scientific means, most objects in white gold have a mark that allows to identify the amount of gold present in the alloy.
What is rhodium and why it is associated with white gold?
Rhodium is a pure precious metal, like gold or silver, but its price is at least 10 times that of gold. It has the property of having a bright white unalterable, although it is too inconsistent to make pieces of this material alone.
In contrast, when talking about white gold is a great ally for its exceptional brilliance, bigger and more durable than silver. Its brilliance, which is usually present in most of the high quality jewelry, and also usually coated the pieces of white gold with a rhodium bath. This brightness has a great inconvenience, and is that with time disappears. The good news is that with a simple new batting, which is not excessively expensive, the piece recovers its mirror-like brightness again.
How were done gold rings before and why they were probably better?
Before the white gold rings were not rhodium plated to get the mirror white shine they have today. Therefore they were produced to keep just white as the resulting mix of metals. Now some jewelers might consider that it is not worth to make them white if anyway they are going to be rhodium plated and look the same. Without considering that soon the plating will disappear and the base color will shine.
The conclusion here is that before buying a white gold plated ring, as your jeweler to make sure that the base ring is white and not just yellow rhodium plated.
The white gold jewelry is beautiful. You can match it with precious stones like emerald, ruby and sapphire, and the combination will be shocking because of its bright colors, but white gold can go with any stone.
