Canadamark Birth Certificates
Most Canadamark diamonds above 0.25 carats include certification and an identity card. The identity card includes the Canadamark number as we have explained on the website in more detail.
The original Canadamark card—a lighter blue version, included several details including the original rough diamond weight from which the polished diamond was cut.
New Card and Design
In recent years, the colour and design of the Canadamark card changed. And, in our most recent orders, the rough diamond weight no longer shows on the card. So the question is, where do you find the rough diamond weight?
Where to Find the Rough Carat Weight
Well, head over to the Canadamark diamond search page.
In the top right hand corner, enter the CM-number as it appears on your card, including hyphen. Hit, enter and a digital version of your card appears.
On the digital version, your rough diamond weight will appear even if it does not appear on the physical card itself.
