Understanding Platinum Purity: What the Marks Mean

When it comes to purchasing jewelry, understanding the purity of precious metals is essential. Among the most popular metals used in jewelry is platinum, known for its rarity, durability, and stunning beauty. However, many shoppers may not be familiar with platinum purity marks and what they signify. In this article, we will delve into the world of platinum purity and shed light on the various marks you may come across when shopping for platinum jewelry.

What is Platinum Purity?

Platinum purity refers to the percentage of pure platinum in a piece of jewelry. The most common purity levels are 950, 900, and 850. These numbers indicate the parts per thousand of platinum in the alloy. For example, 950 platinum means that 95% of the metal is pure platinum, while the remaining 5% consists of other metals to enhance its strength and durability.

The Platinum Hallmark

The purity of platinum is typically marked on jewelry pieces to indicate its authenticity. The most common hallmark for platinum is “PT” or “PLAT,” which stands for platinum. This mark assures buyers that they are purchasing genuine platinum jewelry.

Understanding the Numbers: 950, 900, and 850

The three most commonly used purity marks for platinum are 950, 900, and 850. Let’s explore what each of these numbers means:

  • 950 Platinum: Also known as “Platinum 950,” this mark indicates a purity of 95% platinum. It is the highest level of purity commonly used in jewelry and is considered the most valuable.
  • 900 Platinum: “Platinum 900” signifies a purity of 90% platinum. It is slightly less pure than 950 platinum but still of high quality.
  • 850 Platinum: With a purity of 85% platinum, “Platinum 850” is the lowest level of purity commonly used in jewelry. While it contains less pure platinum, it is still considered a valuable choice.

Platinum Alloys

Platinum is often alloyed with other metals to enhance its durability and strength. Some common metals used in platinum alloys include iridium, ruthenium, and cobalt. These alloys not only improve the metal’s physical properties but also enhance its resistance to scratches and wear.

The Importance of Platinum Purity

Understanding platinum purity is crucial when purchasing jewelry. Higher purity levels, such as 950 platinum, indicate a higher value and a more precious metal. However, lower purity levels like 850 platinum can still be an excellent choice, especially if durability and affordability are key factors.

Caring for Platinum Jewelry

Platinum jewelry is known for its durability, but proper care is still necessary to maintain its lustrous appearance. To keep your platinum jewelry looking its best, consider the following tips:

  • Store your platinum jewelry separately to avoid scratching.
  • Regularly clean your platinum pieces using mild soap and warm water.
  • Have your platinum jewelry professionally polished to restore its shine.

A Timeless Investment

Platinum jewelry is not only a beautiful accessory but also a valuable investment. Its rarity and enduring appeal make it a timeless choice that can be passed down through generations. Whether you opt for 950, 900, or 850 platinum, understanding the purity marks ensures that you make an informed decision when purchasing platinum jewelry.

Summary

In conclusion, understanding platinum purity is crucial when shopping for jewelry. The purity marks, such as 950, 900, and 850, indicate the percentage of pure platinum in the alloy. Higher purity levels generally indicate a higher value, but lower purity levels can still be valuable and affordable options.
