Code of Conduct

15th January 2020

This Code of Conduct sets out how Blacklock Jewellery works with select suppliers. We expect all of our suppliers to adhere to our values in all of their business practices.


Blacklock Jewellery was founded in 1832. From these founding days we have lived by the values of fairness, honesty, integrity and respect. As the business has developed and changed over its 175 years of existence these principles and values have guided us.  

Blacklock Jewellery has the objective to operate as a profitable and responsible fine jewellery retailer, that sells high quality diamond and precious gemstone fine jewellery to Clients. In short we want to sell a superior fine jewellery product, whilst also seeking to uphold our Social, Ethical and Environmental Principles. We want to make a difference and we do this by considering the interests of our other stakeholders: customers, employees, those with whom we do business, and society as a whole.

We recognize that there are indirect impacts generated by our activities, in particular through our supply chain. We will seek to use our influence with those with whom we do business directly, in particular suppliers, to promote the achievement of our Social, Ethical and Environmental Principles.

We choose to work closely with only a very few select suppliers. We expect all of our Suppliers to adhere to these values in all of their business practices, which are articulated through the requirements listed below.  We also expect that our Suppliers will communicate these requirements to all of their Suppliers.
