Hi,
Welcome to the Forum.
The script mark appears to be in Jawi, an Arabic script used in Malaysia, the script appears to translate to the word Kelantan, a state in northern Malaysia which has a tradition of silverwork.
In future posts please refrain from using Photobucket, as they put advertising banners over the detail we need to see.
