Platinum Polishing - No loss of metal

[Jeffreyc87]

There has been a lot of back and forth about polishing gold vs platinum.

Platinum takes more effort to polish, for the simple reason that it does not wear as other precious metals do; consequently, it doesn’t follow the same metallurgical rules.

Platinum has a “liquid” surface. Other metals lose mass over time – prongs wear thin, shanks get thinner, decorations such as Florentine or engravings wear down. All of these deterioration take a lot longer with platinum. The metal even scratches differently.

When you scratch platinum, you are actually just moving the metal aside, whereas other precious metals lose surface area.
