Is antique gold always marked?

Purity marks and makers marks are not compulsory, however. Unlike in the UK, where precious metals must be marked by an assay office in order to be advertised as gold, silver, or platinum, in the USA metal can legally go unmarked. For this reason, USA-made antique and modern jewelry will often be unmarked.

Does a gold chain lose value?

Real gold (10k and up) is much more durable, and its a better choice for everyday wear. In addition, gold-plated chains dont have much of a resale value. With real gold you can always sell it for at least its scrap value. This makes it both a stylish piece of jewelry, and an investment that can go up in value.
