The most common rare metal used for jewelry mounting we could see on the market is 18K gold.
However, there are also many other options like platinum (PT950), 14K and 9K gold. When choosing what to buy, countless consumers would probably run into a question concerning the metals: what are the differences between them?
Therefore, it is a good idea for us to first understand the properties of these metals, and then we can choose the material for our jewelries based on our needs and preferences.
5 strengths of 18K gold
1. Diamond protection
Gold is a stable and corrosion-resistance material which can maintain its luster for years and thus is popular, but jewelries using pure gold (999 gold or 24K gold) are too soft and can deform easily. Using that for diamond ring could mean insufficient protection to the diamond.
18K gold means when the gold is divided into 24 servings, and 18 of them (75%) are pure gold. Then 25% of other metals are added in to create this high purity metal. Mixing with other metals can increase the hardness of 18K gold and this solve the issue of the metal deforming easily. This helps a lot in protecting the diamond, so different kind of gems can also be mounted.
With precise mounting technique, diamond could be securely mounted on the ring and the risk of it falling off could be minimized.
2. Exquisiteness
The decent versatility of 18K gold means that it is suitable for making into different jewelries.
