Here I present a die pressed 7mm Skull on a double band that's 5mm wide X 1.2mm thick. It's got a hammered effect that gives it that aged look. 

This is not Hallmarked as it's below the 7.78g weight threshold for the Assays Office in London but can be arranged at an extra cost.

These will be made to order so please ensure you let me know what size you want.

Don't know your ring size? No problem! Just download a ring sizer app on your phone, grab a ring you wear on your intented finger & let me know what the internal diameter is or what size the app says it is. 

The one pictured has been over polished so your will be better defined.
