Platinum is very different from 18k gold.

The difference between the two materials themselves; I. Platinum

Platinum (Pt for short) will also be marked as Pt*** on ring jewelry, such as pt900/950/990, indicating that the content of platinum is 90%, 95% and 99%. What is the remaining 100%? The remaining 10% is palladium, rhodium, iridium and other elements, which are not garbage impurities, but a blessing to make platinum jewelry "harder" and "more durable".

The characteristic of platinum is that a small piece of platinum with high ductility can be drawn for a long time. Secondly, it is not easy to be corroded and has strong corrosion resistance. After being made into jewelry, it will hardly change color and will not be oxidized at any temperature. The most important thing is that it belongs to a natural white metal, and its comprehensive characteristics such as "naturalness", "corrosion resistance and no discoloration" and "good ductility suitable for making jewelry" just meet everyone's expectations for loyal love, so it was used as a spokesperson for loyal love for a time.

Second, 18K gold

18K The "gold" of gold is gold. Why is it called 18K? The purity calculation method of K gold is to divide completely pure gold into 24 parts. 18K means that 18 is pure gold, that is, 75% is gold, and the remaining 25% is other precious metals, including platinum, nickel, silver and copper. It is usually marked as "AU750" on jewelry, which also means 18K gold.

K gold is characterized by inheriting the precious metal value of gold, and because other components are added, the proportion control is perfect, the ductility is good, and the hardness is greatly improved. Because other metals are added, it can present various colors (18K white, 18K rose gold, 18K yellow, 18K dichroic gold).

It is best to buy 18k gold wedding ring.

Platinum is mostly used as a diamond ring holder, without broken diamonds, and it is a relatively simple couple ring.

18K gold has high hardness and high plasticity, so many high-tech styles can be designed and produced, such as ring arm hollowed out and carved broken diamonds, or ring arm inlaid diamonds, which makes the styles of diamond rings blossom, instead of the fixed style with four claws and six claws, and many stylized design products are also derived, such as rococo style, European retro style, Chinese style and so on.
