1. Look at the back of the nib first to see if there is an obvious gold-bearing stamp, that is, the words 12K (50%) or 14K (58.3 Gym or 58.5%) and the brand (including imported gold pens).

2. Observe the welding place between the iridium particles on the nib and the gold and alloy nib from the side of the nib to see whether the arc between them is clear and yellow. If the yellow and white are unclear or the iridium particles in the tip are yellow or slightly yellow, it can be judged that this gold pen must be a fake gold-plated pen or a fake gold-plated pen imitating titanium.

The pen tip is made of gold and alloy sheets, and the fountain pen with iridium particles spot-welded at the top of the pen tip is called a gold pen. Gold nib is divided into 12K, 14k and 18k according to the gold content (composition). Famous brand gold pens have obvious trademark numbers and models on the mouth of the pen or the surface of the pen tip. There are signs and signs such as quality inspection certificate, manufacturer's name, place of origin, inspector's name or code on the commodity package. There is obvious gold content steel seal on the back of the tip of the golden pen (i.e. 12K or 14K).

Gold, platinum, platinum, rhodium plating, ruthenium plating and platinum plating are different.

If it's a stainless steel nib and some are gold plated, it won't be marked 14K or 18K or 585 or 750.

Many sellers often mislead buyers that this is a gold nib. Actually, it's just gold plating. It's important to look at the logo of the pen tip. There is also a misunderstanding that iridium pens are not gold. It's just that the nib has iridium metal. It has good wear resistance and is a good material for making pen tips.

Not the golden pen that many sellers say.
