Choosing materials for diamond rings: platinum!

Platinum is the hardest material used to make diamond engagement rings. This alloy consists of 95% pure platinum, mixed with Ruthenium. Some diamond jewellery brands speak of a content of as little as 50% platinum mixed with cobalt, but we strongly advise against this choice in order to ensure the resistance and durability of the material.

Platinum is a rare material and has a substantially higher melting point that makes it more difficult to process. Thus it is purer when used. The main advantage of this material is that your platinum diamond engagement ring cannot lose its metallic lustre and perfect white colour. These attributes make platinum more expensive than gold .

At first glance it is very difficult to distinguish between a platinum diamond engagement ring and white gold diamond engagement rings, but thanks to the hexagonal hallmark for platinum content on the inside, the difference is easy to spot.
