If you are still wondering about the hallmark on your Gold Hand of Fatima Pendant, I can tell you that the mark is actually a maker's mark. It is Tunisian and comprised of the registered number of the maker in the center and the point have 2 Arabic letters. This style of mark began in 1955 and has been in use since. The Tunisian Assay Offices would be the only location that the list of makers could be identified.
Hope that helps and sorry that I did not see this post sooner.
