Smokey quartz, Pearl, 14k necklace hallmark help

[navdoch2o]

I picked this up for $15 today. I'm pretty sure it's smokey quartz and golden south sea pearls, the clasp is marked 585 and a hallmark that I'm not familiar with. I think it was a good buy and worth more than 15. If anyone know this makers mark I would appreciate the help. I tried to zoom in as close and clean as i could get on the mark.

It's most likely the mark for the clasp manufacturer - not the necklace. Probably an italian manufacturer.
