To accurately date Napier jewelry, it is imperative to look at the overall style, construction, and components used in manufacture to determine the age of the pieces. This is where it actually gets a bit easier because the styles from the 1920s and ‘30s are oftentimes distinctly different than the pieces Napier made later on, even when using components like metal filigree. The older styles are usually more delicate in appearance, even though they were well made and held up well over time.
