Platinum: What exactly is it?

Platinum is a chemical element with the atomic symbol Pt and an atomic number of 78. It is in group 10 of the Periodic Table of Elements.

Its nearest stimulant 18karat purity white gold is often rhodium plated (it is a technical misnomer to be called white gold anyway), and as such, after a period of wear, the plating would yield to scratches and might reveal a pale yellow layer, which is really the alloyed gold, beneath the coating.

During periods of sustained economic stability and growth, the price of platinum tends to be as much as twice as the price of gold. Platinum is an extremely rare metal, occurring as only 0.003 ppb in the Earth's crust, and is 30 times rarer than gold which is why it is more expensive. It is sometimes mistaken for silver (Ag) but platinum is whiter in appearance. Also, silver tends to oxidise easily on exposure to air and sulphur and readily turns a blackish colour!

With so many advantages over metals like gold and silver, it therefore makes sense to get a ring out of platinum. After all, a ring is meant to evoke all the precious and wonderful memories, so what could be more appropriate other then a platinum engagement ring?
Doesn't that just reminds you of my precioussssss in the movie "Lord of the Rings"?
