The hallmark "950" on jewelry signifies that the piece is made of platinum, specifically 95% pure platinum. The remaining 5% consists of other metals, typically harder alloys like iridium, ruthenium, or palladium. These alloying metals are added to increase the platinum's durability and hardness, making it better suited for everyday wear and resisting scratches and wear. Pure platinum, while beautiful, is too soft for most jewelry applications.
Why is 950 Platinum Used?
Platinum's inherent properties make it a highly desirable metal for jewelry. It's:
- Rare and Precious: Platinum is rarer than gold, making it a more exclusive and valuable choice.
- Naturally White: Unlike white gold, which requires rhodium plating to maintain its color, platinum retains its naturally brilliant white shine over time.
- Hypoallergenic: Platinum is exceptionally well-tolerated by most people with sensitive skin, making it an excellent choice for those prone to metal allergies.
- Durable: While pure platinum is soft, the 950 alloy is much stronger and more resistant to scratches and damage, ensuring your jewelry will last for generations.
How to Identify Genuine 950 Platinum Jewelry
Several factors help authenticate 950 platinum jewelry:
- Hallmark: The presence of the "950" hallmark is the primary indicator. This hallmark should be clearly visible and stamped on the piece, often accompanied by other manufacturer or country markings.
- Weight: Platinum is significantly denser than gold, so a piece of platinum jewelry will feel heavier than a gold piece of similar size.
- Appearance: Genuine platinum has a naturally bright white luster that doesn't tarnish or require rhodium plating. It has a slightly grayish hue compared to the bright white of rhodium-plated white gold.
- Magnet Test: Platinum is not magnetic, unlike many other metals. However, this test should be used cautiously, as it is not foolproof.
What are other Platinum Hallmarks?
While 950 is the most common hallmark for platinum jewelry, you might sometimes encounter other markings, though these are less common:
- PLAT: This abbreviation often appears alongside the 950 hallmark, indicating that the piece is made of platinum.
- PT: A shorter abbreviation for Platinum.
- Country Specific Marks: Many countries have their own additional hallmarks or assay marks that accompany the 950.
What's the difference between 950 Platinum and other metals?
Here’s a quick comparison:
| Metal | Purity Mark | Color | Durability | Hypoallergenic | Cost |
|---|---|---|---|---|---|
| 950 Platinum | 950 | White | High | Yes | High |
| 18k White Gold | 750 | White (rhodium-plated) | Moderate | Usually | Moderate |
| Sterling Silver | 925 | White | Low | Usually | Low |
Is 950 Platinum Jewelry Worth the Investment?
Yes, 950 platinum jewelry is generally considered a worthwhile investment for several reasons. Its rarity, durability, hypoallergenic nature, and timeless elegance make it a treasured piece that can last a lifetime and even be passed down through generations. The initial cost is higher than other metals, but the long-term value and lasting quality often justify the expense.
Remember, always purchase platinum jewelry from reputable jewelers to ensure authenticity and quality. If you have any doubts about the authenticity of a piece, have it assessed by a qualified gemologist or jeweler.
