| platinum |
A metal element whose rarity and unusual tensile strength make it extremely valuable, with a price exceeding even that of gold. It is a heavy, silver-white element that is malleable and ductile and does not corrode. Nor does it tarnish. It needs great heat to fuse, and this durability -- coupled with its harmonious color -- make it ideal as a diamond setting. When employed for jewelry, it is used in the form of a platinum alloy.

Therefore platinum that is 95% pure is generally softer than 90% pure platinum. (See Frequently asked questions)

Platinum is very hard and is extremely long wearing and is very white, so it does not need to be Rhodium plated like white gold. Platinum is very dense making it much heavier than 18k gold. Because Platinum is hard it is best suited for setting the large, valuable stones. ...
