Platinum is one of the world's most precious metals. Used in jewelry, this metal was already known to pre-Columbian civilizations many centuries ago. Platinum is renowned for its brilliance and strength. To help you find out if it's platinum, GOLDMARKET shares a few tips with you. Don't make any more mistakes about the nature of your jewel!

What is platinum made of?

To find out if your jewelry is made of platinum, you first need to know what platinum actually is. Contrary to popular belief, platinum is not an alloy. More accurately, platinum is considered a raw metal. Most platinum jewelry can contain up to 95% of this precious metal. The remaining 5% is made up of other metals that reinforce the jewel's solidity. This is your first clue to recognizing platinum. Because of its mix of metals, platinum jewelry is often heavier than, say, gold.

Knowing if it's platinum: a question of properties

Platinum has many qualities, not least of which are its hypoallergenic properties. By definition, this metal is resistant to its environment. This means it will not oxidize in contact with air. This is a notable difference from silver. In terms of color, platinum can be recognized by its gray appearance. But an expert eye won't mistake it for white gold. 

This is because platinum is anthracite-grey, slightly darker than silver. What's more, platinum is not easily deformed. Even when the metal is scratched, it is sometimes difficult to notice. The signs are often limited to small ridges on the surface.

To find out if it's platinum, the GOLDMARKET team invites you to carry out a little test at home. Place a drop of acid on the metal. This should not affect the quality or appearance of the platinum. Another clue: identify the platinum hallmark. It takes the form of a dog's head.
