This just means the percentage of a particular metal in the jewelry piece, usually silver or platinum. Marked 900 means there is 90% pure silver or platinum mixed with other alloys, as pure silver is very soft, and cannot be used for making jewelry pieces or anything else, without another metal to give it strength, such as copper.
