Jewellery Designing is generally on the State Sponsorship List for one or more Australian States/Territories:
Australian Capital Territory http://www.business.act.gov.au/skilled_and_business_migration
New South Wales http://www.business.nsw.gov.au/live-and-work-in-nsw/visa-and-migration
Northern Territory http://www.migration.nt.gov.au/
South Australia https://www.migration.sa.gov.au/
Western Australia http://www.migration.wa.gov.au
The State Sponsorship List is updated regularly so you need to review each of the related migration websites for latest updates.
