Uncovering the Secrets of Gold karat: A Complete Guide for Beginners

Jakarta, Pintu News – Choosing gold jewelry can often be confusing, especially when it comes to karat. The term “karat” often appears in descriptions of gold quality, but not everyone understands what it actually is. This article will explain everything you need to know about gold karat, from its definition, its use in jewelry, to how to verify its authenticity.

What is rust?

Carat is a unit used to measure the purity of gold. Gold purity is measured by a total of 24 parts, where pure gold has a carat of 24 (24k). This means that there is no mixture of other metals in the gold. Pure gold is very rarely used in jewelry making because it is very soft and scratches easily.

To increase strength and durability, gold is often alloyed with other metals such as silver or copper. This process results in gold that is harder and more suitable for everyday jewelry, but with a lower karat content. For example, 18 karat gold means that 18 out of 24 parts are pure gold, while the rest are mixed metals.

Which Rust is Best?

Choosing the karat of gold depends on personal needs and preferences. 24-karat gold is the purest, but due to its softness, it is not ideal for jewelry that is used frequently. Lower karat gold is stronger and more durable, making it a more practical choice for everyday jewelry.

18-karat gold is a popular choice as it offers a balance between purity and strength. It contains 75% pure gold, which still provides a rich golden color while being strong enough for regular use. 14-karat and 10-karat gold offer higher durability at a more affordable price, making them a good choice for many buyers.

How do you know the authenticity of gold?

Every piece of genuine gold jewelry usually has a stamp or mark of authenticity called a “hallmark”. This stamp indicates the purity level of gold in the jewelry. For example, a 750 stamp indicates that the jewelry contains 75% gold, which is equivalent to 18 carats.

To test the authenticity of gold, one method is to immerse it in water. Gold is a heavy metal, so it should sink. If the jewelry floats, chances are it’s not real gold. Also, check the stamp on the jewelry, which is usually located on the clasp of the necklace or bracelet, or on the inside of the ring.

Conclusion

Understanding the karat in gold is essential when choosing the right jewelry. With the knowledge of what karat is, how to choose a karat that suits one’s needs, and how to verify the authenticity of gold, one can make a more informed decision when buying gold. Always remember to check the authenticity stamp on gold jewelry before making a purchase.
