It is also a partner company of Alius Ltd, a diamond industry consulting company set up in London in 2010, that delivers bespoke professional services exclusively to the diamond industry. The business in Leeds was started in 2017 to give small to medium sized jewellers in the North of England a local and more personalised service.
