Our Expertise

Ethical Sourcing

Known as KPCS, the Kimberley Process Certification Scheme is a joint initiative of governments, organizations in the diamond industry, and private companies to assure a legitimate and ethical diamond pipeline. Created in 2003, together with the Clean Diamond Trade Act that was put into effect in the same year, the KPCS became the foundation for a total conflict-free diamond market spanning the globe. There are currently 54 members of the Kimberley Process from 81 countries, including the EU, which is represented as a single unified member. Members of the KP now constitute 99.8% of global rough diamond production.

Since 31st December 2002, the diamond industry implemented a ‘guarantee’ system of transparency featuring invoices that cover rough diamond, polished diamond, and diamond jewelry sales. Any rough diamonds or finished diamond products made from rough diamonds after that date must comply with the invoicing system in order to attain the KPCS warranty. As part of our commitment to an ethical diamond market, SDE Group partners only with diamond suppliers that are in compliance with the KPCS warranty.

For customers of SDE Group, every diamond purchase comes with the assurance that it was procured from legitimate and conflict free sources. The company takes every step necessary to ensure that our inventory includes no diamonds mined in war zones or from unethical supply chains.
