Please help identify makers mark

[need2know0821]

Hi all! 
 

First post on this forum so hoping this is in the right place. I have a pair of silver earrings with a makers mark that I cannot identify. I’ve tried lots of googling, I’ve image searched using Google Lens but I’ve come up with diddly squat. I believe it to say Haro Bosch but also it could be Hard? If anybody who recognises this mark could let me know more about it I would be very appreciative! 
 

thanks in advance to any and all,

A quick Google found him right away. He's a modern Jeweller in barcelona - he's even on Facebook.
