Hello my name is***** will help you.
Do you intend to DJ in Europe please?
OK - the test is would a customer be confused between you and them.
You are in music, they are in jewellery industry sector. Clearly there is no overlap.
So as long as you dont use the same logo, then you can use the same name, because they are different industry sectors.
I would also consider getting the name Trademarked for DJ purposes.
Can I clarify anything for you about this today please?
