Hi I've got an Imperial 777 and I couldn't see what the difference was between that and the 727. According to Sheaffer guide the 727 is gold plated and the 777 is gold filled. I didn't understand the difference so I looked it up and this is what I found on a jewelry web site https://www.tiffanya...ges/metal-guide The author gives a good explanation of the difference between plated and filled gold .
"Gold filled is the next level and is an amazing, quality alternative to solid gold. Gold plating or vermeil is the lower level and these items tend to tarnish and can often times turn the skin green. I never use anything less the gold-fill or solid gold in my designs.
What is Gold Fill?
It's an actual layer of gold-pressure bonded to another metal. Gold filled is not to be confused with gold plating as filled literally has 100% more gold than gold plating. Gold filled is much more valuable and tarnish resistant. It does not flake off, rub off or turn colors. As a matter of fact, anyone who can wear gold can wear gold filled without worries of any allergic reaction to the jewelry. Gold filled jewelry is an economical alternative to solid gold."
