That would be the hallmark, which is usually the initials of the designer. i.e: "ALE" on Pandora bracelets stand for the founder of Pandora jewelery.
DBJ on a 925 bracelet typically stands for the initials of the designer or brand associated with the piece. The "925" indicates that the bracelet is made of sterling silver, which contains 92.5% silver and 7.5% other metals, usually copper, to enhance durability. If you're looking for specific information about the designer or brand, further research may be needed based on the context of the bracelet.
Sorry to say, but it most likely means it is fake. Google DBJ on ebay and you will see that they produce silver or gold overlay (so gold plated over silver) cubic zirconia items. Sorry about that.
"DBJ" is likely the initials of the person who crafted the piece. It is common for jewelers to use three initials to mark their work. The number 925 is a bit unusual to see on gold jewelry. Numbers such as 916 or 917 (22-karat gold) and 999 (24-karat gold) are more common. If the 925 is inside an oval, the ring is more likely to be sterling silver.

It means u were taken. put a magnet to it ,if it is drawn to it it is metal, but not silver. my wife got rooked on about 10 pieces from a well known on line store.
It's probably a maker's mark indicating who manufactured it (or who the person who counterfeited the item wants you to thinkmanufactured it).Since they're so easy to forge, it doesn't really "mean" anything.
