Hi Sunshine,
Just saw your this query while generally going thru this sub-forum though i go thru other forums quite occassionslly
This may be helpful for you.
You can't distinguisn about this differene between the fake(mae artificially)and real(original) ones with your naked wyes(though very experienced people MAy but im sure u r not that experienced with Gems

)
so you need to go to eomone or yuo may goto Government gemology centers where you cna get them tested.
I hop this will be useful
Regards,
Raman
