Nick Lachey wants a divorce from Jessica Simpson plus all his jewelry back:

From People.com: "According to his divorce response, Lachey cited irreconcilable differences for the dissolution of the marriage. Also, he asked the court to confirm that "miscellaneous jewelry and other personal effects" remain separate property, as well his earnings after the date of separation and additional property assets to be determined."

I haven't been able to find anything specific concerning the jewelry. Is it his? Or was it jewelry he gave to her?
