I have a supposedly white gold choker. It is stamped F on the back. No other markings. Can you tell me what that means?

Thank you for using the Jiskha Homework Help Forum. You don't mention if your choker is antique or not. Between 1883 and 1904, Silver marked with F meant "foreign." If there is a GF on your choker it means "gold filled." Other than that, if you take it to a good jeweler they may be able to tell you more.

The marking "F" on the back of your supposedly white gold choker could have different meanings depending on the age and origin of the piece. Here are a few possibilities:

1. If your choker is antique and was manufactured between 1883 and 1904, the "F" stamp may stand for "foreign." During that time period, the United States required imported silver items to be marked with an "F" to indicate they were of foreign origin.

2. If your choker is not antique and there is also a "GF" marking present, it could indicate that the piece is "gold filled." Gold filled jewelry consists of a layer of gold bonded to a base metal. The "GF" marking would signify that a significant portion of the jewelry is made of gold.

However, since you haven't mentioned the age or other markings on your choker, it would be best to consult with a professional jeweler who can examine the piece in person. They have the necessary expertise and tools to accurately identify the materials and provide more specific information about your choker.
