The “950” mark on platinum jewelry indicates that it is made with 95% pure platinum and 5% other metal alloys. This means the piece is highly pure, durable, and resistant to tarnishing and wear.
Platinum jewelry is typically marked with a hallmark to indicate the purity of the metal. The most common marks used for platinum are “PT” or “PLAT,” but some manufacturers may use “950” or “900” to indicate the purity of the platinum.
The use of platinum in jewelry has a long history and is highly valued for its lustrous white color, durability, and hypoallergenic properties. It is a popular choice for wedding and engagement rings and other fine jewelry pieces due to its rarity and the difficulty in mining and refining the metal.
