The numbers after Pt represent the purity of platinum!

The [900/950] after Pt indicates the purity of platinum.

[Pt900] means that 90% is platinum.

[Pt950] means that 95% is platinum.

The remaining 10% and 5% are other metals known as "alloys." Palladium and ruthenium are used.

It's not that impurities are mixed in to save costs; platinum is soft, so it needs to be mixed with alloys to enhance its strength.

Also, while platinum has a slightly dark tint, mixing it with alloys can remove this darkness.

By the way, the purity of platinum can be raised to 99.95% with modern technology, indicated as [Pt1000].

Since [Pt1000] has no alloys, it is weaker and has a dark tint, so it is rarely used in jewelry.

It is mostly used for storing assets, such as coins or ingots.

Which is better, [Pt900] or [Pt950]?

When choosing a platinum ring, it is important to understand the differences in characteristics, advantages, and disadvantages of [Pt900] and [Pt950].

Compare that with what you desire from a bridal ring and choose which one is better for you.
