FlexThor great question!
However, this is a little broad. We don't even know what gender or country! What's your niche? That can't be just jewellery, what sub category of people are you trying to target? Right now you could almost be targeting everybody which includes tens of millions (if not hundreds) of people!
A great way to find this out is to explain and list your ideal customer. Include a name, personality, their career, age and everything you can think of that would be part of their character. With this information we can start building some more efficient audience suggestions!
