Creating exquisite bespoke jewellery that follows our formal commitment to ethical and sustainable production and manufacturing.

Glacier White and Argyle Pink Diamond Ring

Our company is known for its stance on sustainability and we will only work with long term suppliers who uphold the brand’s formal dedication to a vigilant code of practice as a responsible jeweller.

Calleija exclusively works with only specifically certified diamond cutters who subscribe to the highest ethical standards and the Kimberley Process Certification Scheme (KPCS). These partners are regularly audited to ensure these strict criteria are maintained. We are also very proud of the fact that we are also able to trace to the very mine itself, the origin of the rare Argyle pink and blue diamonds which feature significantly in our creations.

As we have our own workshops which use traditional methods of jewellery craftsmanship, we are able to control the manufacturing process and our customers are assured that our pieces are created under excellent working conditions. With regards to precious metals, Calleija have signed as members of the ‘No Dirty Gold Campaign’ which will formalise the principles by which we have operated with since our conception.

Calleija endorse and subscribe to the principles adopted by the CRJP, Council for the Responsible Jewellery Practices ( which was created in 2005. At Calleija we are committed to continuously improve our ethical, social and environmental performance with the aim to always strive to exceed the limits of excellence.
