Understanding the purity of gold: the mystery of 10K, 14K and 24K

Understanding the concept of “Karat” (K for short) is a crucial first step when choosing a gold bracelet. Karat is the international standard for measuring the purity of gold, which indicates the proportion of gold in an alloy.

Pure gold is defined as 24K, which means that it contains 99.9% or more pure gold. When gold is mixed with other metals (e.g. silver, copper, zinc, etc.) to form an alloy, its purity decreases and is expressed as a value lower than 24K.

The percentage relation between Karat and pure gold content is as follows:

• 24K gold: Theoretically 100% pure gold (actually 99.9% or more).
• 18K gold: contains 75% gold (18/24 = 0.75);
• 14K gold: contains 58.3% gold (14/24 ≈ 0.583).
• 10K gold: 41.7% gold (10/24 ≈ 0.417)

Different karat values not only represent differences in gold content, but also have a direct impact on the physical properties, appearance and value of gold bracelets.

The higher the purity of gold, the more golden its color, the softer is the texture, but also the higher the value retention; while the purity of the lower K gold, due to the addition of other metals, the hardness will be higher, wear resistance is better, the color may also present a more diverse range of shades (eg, rose gold, platinum) but the value retention attributes of gold itself will be relatively weaker.

In addition, different alloy compositions may also affect the wearer’s allergic reaction; the purer the gold, the lower the risk of triggering allergies is usually.

Authoritative quote:

* According to the Gemological Institute of America (GIA), a krat is a measure used to express the purity of gold, with 24 karat representing pure gold. The lower the karat number, the less gold there is, but usually the harder it is.” (Source: GIA official website Jewelry Encyclopedia)

Question 2: “Are gold bracelets allergic?”

Answer: Pure gold (24K gold) is an inert metal and rarely causes allergies.

However, K gold (such as 10K and 14K gold) is an alloy of gold and other metals, and the nickel, copper and other components in it may cause allergic reactions such as redness and itching of the skin in a few people who are allergic to these metals.

If you have sensitive skin, it is recommended to choose high karat gold (such as 18K or 24K) or alloys that are clearly labeled as “nickel-free”.

Question 3: “Will gold bracelets lose their color?”

Answer: Pure gold (24K gold) will not lose its color, because it is golden yellow.

k gold (such as 10K, 14K) will not lose its color, but the non-gold components may have chemical reactions with sulfur, chlorine and other substances in the air resulting in oxidation of the surface darkening or loss of the original luster.

In addition, some K gold products (especially white K gold) surface may be rhodium-plated if the plating wears may reveal the color of K gold itself, but these cases can be restored or even re-plated by professional cleaning and polishing.
