Canadian Fire - The four C's

To carry the Canadian Fire name, a diamond must meet specific and very narrow criteria for colour, cut, clarity and carat weight.

Only diamonds that are graded as ‘excellent’ or ‘very good’ with regard to cut, symmetry and polish can bear the CanadianFire brand. CanadianFire diamonds are cut to maximise optimal brilliance, not size. Every CanadianFire diamond falls within a narrow and specific range of parameters for colour – D to G, and clarity IF to SI2.

Since 1939, the ‘4 Cs’ have defined the quality and rarity of a diamond. Now those who buy diamonds must also be concerned with a fifth C - Certified Origin. Every CanadianFire diamond comes with an assurance that guarantees the country of origin, authenticity and high standards of quality. Regular due diligence inspections and audits ensure the integrity of the manufacturing and grading facilities where your CanadianFire diamond transforms from rough diamond to cut diamond.
