Gambar What is the 24 Karat Gold Code? A Complete Guide to Grades & Standards

Jakarta, Pintu News – 24-karat gold is the highest purity form of gold most recognized in the global precious metals market. It has a pure gold content of close to 99.9 percent with no admixture of other metals, so it is often the top choice for investment bars or coins, not just as everyday jewelry due to its relatively soft nature.

The code standards for 24-karat gold also distinguish it from other types of gold such as 22K or 18K, making it easier to identify quality and value. The following is a complete explanation of the meaning, code, and function of the 24 karat gold grade based on technical references and industry practices.

Meaning & Grade of 24 Karat Gold

24-karat gold (24K) is the highest purity gold, meaning that all of its components are almost entirely gold with no alloys of other metals. In the grade standard, the number “24” indicates the total gold part out of a total of 24 parts, so the purity is calculated as 24/24 x 100% or about 99.9 percent gold purity.

Due to such a high level of purity, 24-karat gold tends to be very bright yellow in color and has a stronger luster than lower grades. However, its malleable physical properties make it less ideal for jewelry that is often worn on a daily basis as it is easily scratched or deformed.

24 Karat Gold Code & Marking System

In gold marking practice, the coding system usually uses numbers that indicate the grade or percentage of gold in millesimal or carat form. 24-karat gold is generally coded 999 or 999.9, which technically means 999 parts pure gold out of 1000 total parts, or about 99.9 percent purity.

This code is the industry standard for indicating near full purity, as opposed to the 916 code for 22K gold (91.6%) or 750 for 18K gold (75%). This code system helps buyers and sellers quickly identify and compare gold grades when buying and selling.

Code Function & How to Verify Gold Content

Codes such as “999” on 24-karat gold are not just numbers, but part of the hallmarks of authenticity that are mandatory on certified precious metals. In addition to the grade number, certified gold products often come with hallmarking that includes the certification body’s logo, carat value, fineness (millessimal) value, and a unique identification code (HUID) that indicates that the gold has been officially tested.

This process is important because it ensures that the gold purchased is of the right quality and purity according to the code, thus protecting consumers from fraudulent practices.

Conclusion

24-karat gold is the purest form of gold with a purity level of almost 99.9 percent, marked by the code 999 or 999.9 which indicates almost entirely gold with no other metals mixed in. This code makes it easier to identify the grade when buying or selling gold as a precious metal.

Due to its extremely high purity, 24 karat gold is often chosen as an investment instrument such as bars or coins rather than everyday jewelry. Understand the codes and hallmarks on 24-karat gold to ensure quality and avoid risks when dealing in precious metals.

Gold-Based Crypto: When Physical Assets Meet Crypto Technology

As blockchain technology develops, gold can now be owned not only in physical form such as jewelry or bars, but also in digital form through gold-based crypto assets.

One of the most popular is Tether Gold (XAUt), a physical gold-backed ERC-20-based stablecoin, where 1 token represents 1 troy ounce of pure gold. The gold is stored in vaults in Switzerland and each token is directly linked to certified gold bullion. The system uses automated algorithms to efficiently manage the allocation of gold and Ethereum addresses.

XAUt tokens are available and traded on various crypto exchanges. XAUt is also an attractive alternative for those looking to hedge against inflation or global economic uncertainty, while remaining within the digital asset ecosystem.
