Canadian jewellery business industry

Hello dear members, I am writing a business plan, and was hoping to
find on Canadian jewellery (small and large business)
industry. I need numbers to demonstrate that it is a rather stable
industry. 5 year turnovers specifically, new jewellery businesses
since 2005 that kind of thing. I have been on business websites of
all sorts, and have not found target that satisfied my
needs. Thanks for any useful info !
