If it's British gold or silver, the symbols all mean something pretty specific. They should tell when, where, and what it's made out of (the metal--not the stone). The anchor I think means it was marked in Birmingham and the rest um oh I can't find the chart.

Doesn't tell you what it's worth of course. I think it's classy, paste or not! And yeah, get a second opinion. :)
