When in Brighton, i bought an Opal ring, although i originally wanted a turquoise stoned ring, my eyes caught a blue opal ring. Turned off by the negative attachments to Opal, being unlucky, i bought the ring due to the draw it had to me. Looking and researching the stone i found out this amazing fact: That being aware that there are such things as synthetic opals, i decided to take this test- real Opals turn florescent under a black light, unlike synthetic ones, just as well i have one- and- YES it is real 
My engagement ring is Opal, and I am very lucky in love! Opals are quite brittle and they hate getting wet so they can break easily and that seems to be the reason they got an ‘unlucky’ reputation. They like being in contact with he oils on your skin and prefer to be worn, rather than kept in a box.
In case you didn’t guess they are my favourite stone! The synthetic ones look synthetic in the daylight and at night with the lights off, but I didn’t realise they were luminous, that is really interesting. So appropriate for you too.
