SEPTEMBER 21, 2026
Last date for transitioning
to revised System of Warranties
The five-year transition period for the WDC’s Revised System of Warranties (SoW), introduced in 2021, will conclude on September 21, 2026.
By that date, the revised SoW Declaration should apply not only to rough diamond purchases, but also to polished diamonds and diamond jewelry.
From thereon forth, the revised declaration will be the only applicable System of Warranties reference for any diamond transacted within the WDC framework.
What Companies Should Do:
Companies trading in rough and/or polished diamond and/or diamond jewelry should ensure that:
“The diamonds herein invoiced have been purchased [or “sourced”*] from legitimate sources not involved in funding conflict, in compliance with United Nations Resolutions and corresponding national laws [where the invoice is generated**]. The seller hereby guarantees that these diamonds are conflict free and confirms adherence to the WDC SoW Guidelines.”
* “sourced” may be used by companies that do not purchase from open market, but source and aggregate diamonds from production facilities that are owned/partly owned by them.
** “where the invoice is generated” may be used by companies if they specifically want to reference the country of invoice issuance.
