Canadian Diamonds
About the data
Diamonds that are labeled as Canadian diamonds are guaranteed to be conflict free in that they originate in a country of peace where there is no armed conflict. Most diamonds mined in Canada are shipped to India and Africa for cutting and polishing. Only those with the added certification of being from the Northwest Territories are cut and polished in-country. Of the five diamond mines in Canada, only 1 is majority owned by a Canadian company.
Methodology
When a company uses Canadian diamonds instead of sourcing from Africa, it showcases a deeper interest in sourcing minerals responsibly.
To add a value to this metric, search "Company Name - Canadian Diamonds" and check for publications which state that the company sources its diamond from Canada.
If you find this publication, input the value "Yes", citing the source and Year.
