When buying such a thing, it is intended that the item will be a lasting symbol of an eternal sentiment.
One thing to look for in such an item is the use of rhodium as a plating.
Rhodium is a precious white metal from the platinum family. It costs roughly 8 times more than pure gold, and 4 times more than platinum.
The main benefit of plating an item with rhodium, is the extra durability it provides. In fact, it is now a common practice to plate fine white gold with rhodium.
And let's not forget the gorgeousness factor. The appearance of rhodium is arguably even more beautiful than white gold.
And that is why modern quality items, like the one pictured above are more and more likely to feature rhodium as an add on.
Now you know.
