What are CanadaMark Diamonds?
The CanadaMarkâ„¢ hallmark program is a strategic initiative of Dominion Diamond Corporation to assure the integrity of the supply chain of Canadian Diamonds from mine to the retailer. It gives the end consumer of Diamond jewellery confidence in the origin and history of their polished Diamond. This unique number can be entered online to verify the Diamond's authenticity and origin. You will need your serial number and polished Diamond weight.

Your CanadaMark Diamond can be set into one of our Engagement Ring designs. Please see our dedicated information page on traceable diamond engagement rings for additional guidance.
Every CanadaMark Diamond comes with the reassurance that it is :
- Responsibly mined in Canada
- Natural and untreated
- Traceable to the mine
- Meets specific quality standards
At Serendipity Diamonds we are actively engaged in establishing fully traceable supply chains for Diamonds from the mine to the final product.
As part of our service we can provide traceable CanadaMark Diamonds originating from the Ekati and Diavik mines in Canada.
Are CanadaMark Diamonds ethical Diamonds?
Yes, absolutely. In addition, Canadamark Diamonds offer the only 100% traceable system for ensuring your Diamond is completely ethically sourced. Even Diamond under the Forevermark brand by DeBeers do not give assurance of where precisely a Diamond originated.
CanadaMark cards and CanadaMark inscriptions
Fully traceable Diamonds provide the consumer with a documented information on the origin of their Diamond. Each Diamond carried authenticated information on where the Diamond was originally mined. All of our Diamonds are conflict free which is noted on each invoiced Diamond product. Fully traceable Diamonds give the consumer the additional information relating to where the Diamond was mined. Although supply is limited, we can provide a wide range of Diamond shapes, sizes, colours and clarities with fully traceable credentials.
We receive varying goods in different Diamond shapes, colours, clarities and sizes depending on availability. Please contact us with any specific requirements.

The Diavik Mine
The Diavik Diamond Mine is Canada’s largest Diamond mine in terms of carat production. Diavik was established following the discovery of four Diamond-bearing deposits, called kimberlite pipes, in 1994 and 1995.
The mine site is located in Canada’s remote wilderness on a 12 mile square island, at Lac de Gras, Northwest Territories, approximately 185 miles from Yellowknife, the territorial capital, and just 136 miles south of the Arctic Circle.
The Ekati Mine
The Ekati mine is located in in the Lac de Gras region of the Northwest Territories, approximately 185 miles northeast of Yellowknife, Canada. The name means 'Fat Lake.' It is Canada's first surface and underground mine in production since 1998.
BHP Billiton completed the sale of its Diamonds business, comprising its interests in the EKATI Diamond Mine and Diamonds Marketing operations, to Dominion Diamond Corporation (formerly Harry Winston Diamond Corporation).
