Understanding Platinum Purity

Platinum is a highly sought-after precious metal that is prized for its beauty, durability, and rarity. It is a popular choice for jewelry, particularly engagement rings and wedding bands. However, like gold, platinum jewelry can vary in purity, which can impact its value and appearance. In this blog post, we'll explore the concept of platinum purity in jewelry and why it matters.

 

Understanding Platinum Purity


Platinum is a naturally occurring metal that is mined from the earth. It is typically mixed with other metals to create an alloy that is suitable for use in jewelry. The purity of platinum is measured in parts per thousand, also known as "fineness." For example, 950 platinum is 95% pure, while 900 platinum is 90% pure.


In the United States, platinum jewelry must be at least 50% pure to be considered "real" platinum. However, higher fineness values are typically preferred for their greater value and durability.


Hériter Gems only utilizes a 95% pure (950/1000) alloy in its fine platinum jewelry to provide our clients with the most durable product with the best value retention.


Platinum Purity and Appearance


The purity of platinum has a significant impact on its appearance. Higher fineness values result in a brighter, whiter color that is highly prized in jewelry. However, pure platinum is also softer and more malleable than lower-purity alloys, which can make it less suitable for certain types of jewelry.

Lower-purity alloys are often used for jewelry that requires greater durability, such as engagement rings or wedding bands. However, these alloys may have a darker color and lower value than higher-purity platinum.

 

Platinum Purity and Value


The purity of platinum also affects its value. Pure platinum is more valuable than lower-purity alloys, and the value of platinum jewelry is typically based on its weight and purity. This means that higher-fineness platinum jewelry is generally more valuable than lower-purity pieces of the same weight. However, other factors also come into play when determining the value of platinum jewelry, such as its design, rarity, and historical significance.


Platinum purity is an important factor to consider when purchasing platinum jewelry. It affects both the appearance and value of the piece, and higher-fineness platinum is generally more prized than lower-purity alloys. If you're in the market for platinum jewelry, be sure to consider the fineness value and choose a reputable jeweler who can provide you with accurate information about the piece.
