Diamond Shape Band ring

[jpo31]

Hi! I am a relatively new jewellery maker and a friend has asked me to make a ring that would be a band of diamond shapes. I've drawn that quick pic attached below. I guess I am wondering the best way to do it. I am not very experienced in wax but I think that might be 'easiest'? Abit worried about getting all of the diamonds consistent size. Is there any advice on what more experienced jewellers would do? Thank you.
