How To Tell If It Is Real Opal?
How To Tell If It Is Real Opal & Gold Question: I have just purchased a brooch from a flea market of all places, it caught my eye and I really liked it.
Opal: The Phenomenal Gemstone
Price: $40.00
It is pretty simple gold in colour with what looks like an opal in the middle but I would like to know what the markings on the back mean..... K T G F and what looks like a 'Y' attached to an upside down 'T' and the remains of 2 backwards 'S' joined together.
The opal looks red/dark pink when held up to artificial light?
I would just like to know how I can tell if it is a real opal and what the metal is?
I hope that I have the correct place to ask this question, if not I apologize.
Many thanks for your time.
