Its the details of the piece of jewelry.
The "SU" is the maker's mark, which is Silver Unlimited,http://www.silverunlimitedinc.com/aboutus.aspx.
The 925 means 925 parts out of 1000 are silver, and 75 parts are some other kind of metal, usually copper, sometimes nickel. This grade if silver is very stable and not easily broken or bent. It is considered the ideal silver grade for making jewelry and in the US and some other countries is called "sterling." It is also often denoted as .925 or Sterling.
The CZ CH probably stands for CZECH, the marking for things made in the Czech Republic, but when the mark was struck the "E" didn't print. It is not unusual, especially on curved surfaces such as rings and bracelets, since not all the letters in a stamp may have good contact with the surface when it is struck.
So, it looks like your item was made in the Czech Republic of sterling silver for a company called Silver Unlimited.
