Any Gold Jewellers On This Forum

[SpitShine]

As the title suggests, i'm after someone who's relatively familiar with gold jewellery. my gf brought me back a gold ring from asia and is concerned as to whether its real gold or not because she paid quite a bit of $$ for it. There's a stamp imprinted on the inside but even with a magnifying glass i can't make it out. I know that in australia they use the metric % to distinguish real gold using these stamps:

10 kt is 375
14 kt is 485
18 kt is 750

Some people are telling me that if you scrape off a bit and it peels then Wallah! its plated or the way it shines... but i'd rather some1 who knows their stuff to analyze it..
