Need Help with Arabic or Iran Silver Marks

Can someone help translate these silver marks from a 3" tall silver vase that I believe to be from Iran? I’ve learned the pic is upside down and the top mark is arabic for the 84 silver standard. Does anyone have a source of info for Arabic silver marks, or, for that matter, Arabic silver in general? Thank you.

your silver piece is made in Iran in Isfahan city.
the purity is 84%
marked by parvaresh( i think reza parvaresh)
parvaresh is greatest family in Isfahan in making handcrafted silver.
