I have an 18" gold chain necklace, on the clasps link it has 585 on the opposite side there is a star with 763VI, what does that mean?

"On a gold ring the stamp 585 is meant to indicate that it is 58.5%, or 14 karat gold. However, I urge anyone wishing to buy jewelry to be very careful when judging gold by the marking. If you are dealing with a reputable jewelry store or jeweler, you are probably safe but remember, if you stamp 14 k on a pile of dog poop, it's still a pile of dog poop. Stamps are easy to get and it's better to insist that the gold be tested while you watch or test it yourself before you buy than to realize you have been taken later."
