All gold plating used on our pens is 24K “upgrade gold”. Upgrade means that the parts are plated using the rack method and that small amounts of cobalt or palladium are added to the plating chemicals. This enhances the durability of the gold plating. The tumbled method, which we do not use, produces an inferior gold plating and is less costly.
This is an extremely durable plating. Under normal use this plating should hold up for many years.
A more attractive finish that is slightly more durable than the 24k gold.
This a very durable hard plating. We use real platinum rather than rhodium and it should be expected to hold up under normal careful use for many years.
This is titanium oxide molecularly bonded (PVD). This plating is unbelievably hard and durable. It will last for many, many years.
This method produces extremely durable and the most durable plating. The process used is called PVD (particle vapor deposition). Titanium nitride matched to the color of gold is molecularly bonded to the part and then 24K gold is bonded (sputtered) on the part to achieve a color match to our other gold parts. The parts are again re-plated after this. The final result is that the parts will virtually never show wear.
This a very rare and unusual plating. Copper and gold are combined in such a way that they both plate with their atoms equally mixed together. The parts are specially treated before plating and the plating is deposited in a very thick layer. Not only does this produce a beautiful sumptuous look but is very durable. It has been indicted to us that there are only two companies in the world able to do this plating and that under regular careful use the plating should hold up for several years.
