When you start looking for wedding or engagement rings, you’ll often come across the material designation “Pt900.”
But many people probably wonder, “What does that number mean?” or “How is platinum different from other materials?”
Here, we’ll explain the characteristics and appeal of Pt900 in a way that’s easy to understand, even for first-time ring shoppers.
What is Pt900?
・A material made from platinum with a purity of 90%
・The remaining 10% consists of an alloy of palladium, ruthenium, and other metals to enhance its strength
・A well-balanced platinum alloy that combines a “beautiful white luster” with “high durability”
Why Pt900 is chosen for engagement and wedding rings
1. Resistant to discoloration and deterioration
Compared to gold and silver, it is more resistant to air and sweat, so it is less likely to change color during daily use.
2. Hard and durable
It is harder than pure platinum (Pt999), making it a reliable choice for wedding rings worn every day.
3. A material that symbolizes eternity
As a “symbol of everlasting love,” it is a classic choice for engagement and wedding rings.
The Difference Between Pt900 and Other Materials
・18K Gold: Available in a wide range of colors and has a lustrous appearance, but compared to platinum, care must be taken regarding its hardness and susceptibility to discoloration.
・Pt950: Has a high purity and a more striking whiteness, but because it is slightly softer, it may be prone to scratches depending on the design.
・Pt900: Offers a good balance of hardness, durability, and luster, making it a reliable choice for everyday wear.
Pt900 is a material that combines a beautiful white luster with exceptional strength, making it the perfect choice for engagement and wedding rings.
It continues to be chosen by couples who want peace of mind when selecting a ring they will wear every day for years to come.
