Platinum is extremely dense, and remarkably heavy. Much more so than silver or gold. This property of platinum enhances and ennobles the quality of the jewelry from which it is created.
I might be sidetracking a bit, but I think this is interesting. Everyone knows alchemy, right? mixing of different (cheap) materials to create something more valuable, like gold. There is one successful way using alchemy to create gold, but it requires platinum. Which is more expensive than gold. Guess there is no such thing as free lunch.
Understood to some extent. But I think gold cannot be adulterated in any way. The advance testing technology will find out everything.
