Collection: 14 Karat Gold Bangle Bracelet

Why gold carat is so important when choosing your 14 Karat Gold Bangle Bracelet?

"Aurum" is the Latin word for gold, the chemical symbol for gold is "Au" in reference to it.
Gold is a precious metal and as such is characterized by high chemical resistance to its environment. It is very inert and resistant to corrosion, only a few chemicals are able to dissolve or dissolve it.

The melting point of gold is 1065 ° C. Compared to platinum (1772 ° C), this is a moderate melting point, which results in a comparatively easier processability of gold over platinum.
Pure gold is soft. Pure gold and gold alloys with high gold content are therefore only partially suitable as a material for jewelery production.

The jewelry made from it scratched, bends and deforms quickly. Gems can not be captured safely.

Gold is a heavy metal and as such has a very high density, namely 19.32 g / cm3. The density of gold is thus 19.32 times greater than that of water (density is the ratio of mass to volume). The ductility of gold is very high (ductility translates roughly as "ductility"). For example, gold has the greatest extensibility of all metals and can be hammered into extremely thin gold leaf (see Section 3: Gold in Comparisons).

What is a gold alloy?

If two or more metals are mixed by melting, it is called an alloy. When gold is alloyed with one or more other metals, a gold alloy is formed. It is important that in everyday language with gold not only pure gold is meant, but also its gold alloys.


Why are gold alloys used?

By alloying other metals to gold, its properties change and its processability can be optimized. For example, one obtains changes in hardness (generally increased by alloying), melting point, density, color, and more. Gold is also alloyed for cost reasons.

Why is there gold in other colors than yellow?

Pure gold is always shiny yellow. However, gold alloys (which are simply called gold in everyday language) can have different colors and shades - depending on which other metals are settled in the gold in which proportions.

Which gold colors are there?

The most important gold colors are yellow, red and white. One then speaks of yellow gold, rose gold and white gold. In addition, it is also possible, for example, to produce green gold alloys.

For a 75% gold alloy (i.e., 18 carat gold 750 gold), adding 25% other metals will result in the following colors:

Yellow: The gold is mainly copper and silver settled in equal parts.
Red: The gold is mainly copper settled. The more copper is settled, the more intense the coloring becomes.
White: The gold is settled as a coloring metals either palladium or nickel. Accordingly, one differentiates between palladium and nickel white gold. Palladium white gold is largely composed of gold, palladium and silver in addition - nickel white gold mostly of gold, nickel and copper.
Green: The gold is settled in front of all silver. Green gold is used in jewelry processing, for example, to imitate the most lifelike leaves.

What do the following terms mean on gold jewelery:
750, 585 and 375?

The three-digit numbers indicate how many parts by weight of a gold alloy - of a total of a thousand parts - consist of pure gold. One speaks then of the so-called fineness or simply of the fineness of the gold.

The hallmarking of a 750, 585 or 375 piece of jewelery means that it has a gold content of 750/1000, 585/1000 or 375/1000, i. 75%, 58.5% or 37.5%.

What do the following terms mean on gold jewelery:
18K, 14K and 9K?

The K stands for Karat. Karat is the percentage by weight of pure gold in a gold alloy. The designation 24K stands for pure gold, 1K stands for a gold portion of 1/24.

The hallmark of a piece of jewelery with 18K, 14K or 9K means that it has a weight percent gold content of 75% (18/24), 58.5% (14/24) or 37.5% (9/24).

Comparison of the carat specification and the specification of the fineness of gold
Gold content (%) Carat statement Specification of fineness
In Switzerland, the indication of the gold content in Karat is outdated, it is done by specifying the Feinghaltes.
100% 24K 999.9
91.6% 22K 916
75% 18K 750
58.5% 14K 585
37.5% 9K 375
Karat has a second meaning next to it. The carat is also a unit of measurement for gemstones.
