Hallmarks on gold bracelet bought in Saudi Arabia

I have been asked to research what the marks mean on this gold bracelet.

The full list of marks as they appear is

5 pointed star 255 VI 875

Looking on this site I have found the following info from other posts.

"21 carat gold, fineness of 875 is the recognized standard in Arabic countries."

And

"VI is the abbreviation for the Italian province of - Vicenza."

Can anyone fill in the gaps?

Thanks
