Analysis of 18K white gold and PT950 platinum ring materials
When choosing a wedding ring or engagement ring , the material of the ring is very important. Among many materials, 18K white gold and PT950 platinum have always been the most popular choices. This article will give you a detailed introduction to the characteristics and differences of these two ring materials to help you find the most suitable option.
1. Ingredient Differences
First, let’s understand the main differences in composition between 18K white gold and PT950 platinum:
- 18K white gold: It is made of 75% gold and 25% other white metals (such as silver, palladium, etc.). The surface is usually rhodium-plated to show a bright white luster.
- PT950 platinum: contains 95% platinum and the remaining 5% is other metals (such as rhodium or copper). Platinum's rarity and corrosion resistance make it a high-value and durable material.
2. Weight and hardness differences
18K white gold and PT950 platinum also differ in weight and hardness:
- 18K white gold: It has a lower density and is therefore lighter, making it suitable for those who prefer a lightweight ring. It has moderate hardness, is easy to process, and can be used to create a variety of exquisite styles.
- PT950 platinum: higher density, heavier weight, and more "quality feel" when worn. However, platinum has a lower hardness and is easily scratched or deformed, so it requires more careful protection.
3. Antioxidant
There are also obvious differences in the oxidation resistance of these two materials:
- 18K white gold: Because it contains other metal components, the surface may turn yellow due to oxidation after long-term wear.
- PT950 Platinum: Platinum has extremely high antioxidant properties and can maintain its original luster even when worn for a long time without turning yellow.
4. Price Difference
There is also a clear price gap between 18K white gold and PT950 platinum:
- 18K white gold: Due to its lower gold content, it is more affordable than platinum and is an ideal choice for consumers with limited budgets.
- PT950 Platinum: The rarity and high purity of platinum make it more expensive, and it is the first choice for consumers who pursue high quality and luxury.
