1. How Gold purity is measured
The content of chemically pure gold in a metal alloy can be determined by gold fineness. It indicates how many units of mass of pure metal are in 1000 units of mass of an alloy. For example, if an alloy contains 58.5% of the pure element, it would be 585 gold, etc.
2. What is the meaning of ‘KARAT’?
The term “karat” comes from the Arabic word “qirat” and refers to the proportion of pure gold in the alloy. One carat of gold is equal to 1/24 part of pure gold in the alloy. Therefore, 24-carat gold is pure gold, while 18-carat gold contains 75% gold (18/24). Carat values can vary, and what a carat is can be understood as a measure of the gold content in an alloy. The carat allows us to assess the value and quality of gold. The higher the carat number, the higher the gold content. This translates into investment and aesthetic value. Higher carat content also means higher resistance to corrosion and abrasion.
3. Gold colors.
– yellow gold – with the addition of silver, copper and zinc. The percentage of each ingredient affects the final color.
– However, nickel is an allergen, and EU law limits the use of nickel in items that come into direct contact with the skin, including jewelry. In white gold, where over 60% of the alloy is yellow gold, it’s hard to get a uniform white color, so white gold will always have a yellow tint. Most jewelry companies use white gold rhodium plating technology, which covers jewelry with a thin layer of rhodium. The resulting effect is a snow-white color, which is commonly known in the trade as white gold
– red gold – an alloy of gold with silver and the addition of copper. The intensity of the color depends on the proportion of silver and copper. The more silver present, the more delicate the hue (pink), whereas the more copper present, the more intense the hue (red)
– Pink gold is gold with an alloy of silver, copper, or zinc and palladium
– green gold – with the addition of silver, copper and cadmium
There are also colors: purple with aluminum and blue with iron, but they are less popular.
4. What quality of gold should I choose?
Frequently, a lesser grade of gold is referred to as “bad quality”. The more fine the metal is, the more valuable it is. But we shouldn’t leave out the less fine metal, especially if we plan to wear gold jewelry every day and don’t want it to get damaged easily. Fineness of gold affects the properties of jewelry made of this metal. The finer the material, the softer it becomes, affecting its durability and resistance to nicks. Lower purity gold, such as 9k gold, is more resistant to damage, but contains less pure gold. This may affect the appearance and value of the jewelry. Choosing the right sample depends on your individual preferences, the intended use of the jewelry, and your budget.
