I found out from my mother that my great-grandfather in Germany worked as a jeweller prior to World War II. I never got to meet him, in fact, there are no existing photos of him either that I am aware of. So anyway, I thought it would be nice to honour him with something jewellery related, I am open to all ideas, any for a boy would be great as well! Thanks Berries!

[name]Diamond[/name] and [name]Emerald[/name] were originally used as boys names, and as a middle name, I think it would be pretty cool. 
For girls, I like [name]Esmeralda[/name], [name]Onyx[/name], [name]Opal[/name], and [name]Clara[/name] (the name just reminds me of sparkling rubys, I don’t know why).
Hmmm, so metals, gemstones and things like that?
