What does au750YCM jewelry mean

The "AU" in "AU750" is the chemical element symbol of "gold", which indicates that this jewelry contains **. "750" is the gold content expressed in thousands, that is, the gold content is 750 thousandths (i.e. 75%).

The gold content of 1k gold is, multiplied by 18, which is 75%. Therefore, "AU750" means that the jewelry is "18K gold".

On 18K gold jewelry, there are also marks such as "750", "18K", and "G18K", all of which indicate that "the jewelry is made of 18K gold".

18k gold, in addition to 75% **, contains 25% of other metals. These 25% of other metals, due to the different types of metals used and the different content ratios between various metals, can be smelted into 18K gold of different colors. For example:

18k yellow gold with copper, silver ---.

Contains silver, copper--- pink 18k gold (more silver than copper).

18k gold with aluminium --- red.

Silver, zinc, nickel --- silvery-white 18k gold.

18k gold with silver, cadmium, copper --- green.

Iron-bearing --- blue 18k gold.

The "jackpot" that is common in the market today is actually a combination of 18k gold of various colors.

18K gold jewelry not only has the most precious value, but also has the advantages of strong ductility, high hardness and changeable color because of its perfect composition.

The gold content of 18K gold is the general specification of jewelry, and the state stipulates that ** jewelry below 9K cannot be called ** jewelry.

Its provisions are: pure gold - gold content is not less than 99%, 1,000 pure gold - gold content is greater than China has regulations on the first product imprint and identification plate, generally requires the manufacturer code, material name, content imprint, etc., no imprint for unqualified products.
