platinum shades?

[Cehrabehra]

You all know there are different colors of gold - yellow, white, rose or red, not to mention green and purple LOL

Why AREN''T there different shades of platinum? No one uses 100% platinum... and you see plat up NEXT to shades of gold sometimes in a ring... so it bonds with gold... but why don''t you see yellowish platinum or pinkish platinum?

Is there a chemical reason or has no one experimented?

For the same reason you don't see 23K white gold, pink gold, etc.

95% pure makes it almost impossible to color.... unless you plate it. A lot of pink gold for example is plated pinker, because 18K pink gold alloy is still somewhat yellowish looking (looks kind of orange actually).

The best colors in white and pink gold are actually 10K, but of course they get dirty a little quicker then 14K and need to be cleaned more often.

I suppose you could make a 14K (58.3% pure) platinum mixed with 10K (41.7% pure) alloying metals like copper to make "pink platinum"

Yes, I always thought this was because PT was usually 95% pure, and you usually don''t see white or pink gold at such high kt weight either.
