Diamond engagement rings should be analyzed using the 4Cs: cut, colour, clarity, and carat. Carat refers to the size of the stone and is often considered by many to be the most important factor. However, cut, colour, and clarity also affect the qualty of a diamond. Cut is the most important quality to a round brilliant diamond; as it can make the diamond look dull and lifeless if not up to par. All Birks diamonds are selected with an excellent cut, the highest grade. Colour ranges from D, absolutely colourless, to Z, a diamond with a light yellow hue. Birks' diamonds are selected with a colour range between D and I. Clarity refers to the inclusions presented on a diamond. The higher the grade, ranging from FL to SI2, the less like you'll come across inclusions in your diamonds. Birks is committed to providing diamonds with a clarity range from FL to SI1.

Since 1879, Birks has set the standard across Canada for quality diamonds providing meticulous grading and certification for clarity, colour and proportions according to rigid international gemological standards. Birks was also among the first to support and work with the Kimberley Process insuring integrity of the supply chain. Birks sources diamonds from only the most reputable purveyors or cutters who declare on their invoices that the diamonds sold have been obtained in compliance with the Kimberley Process. Birks also reserves the right to audit their diamond suppliers to ascertain compliance. In May of 1999, Birks was the initiator of a program that would provide complete tracking of Canadian diamonds and became one of the first jewellers to acquire and sell diamonds mined in Canada.

Birks is also a signatory of the Voluntary Canadian Code of Conduct for Authenticating Canadian Diamond Claims. Birks uses Canadian diamonds in the creation of its bridal jewellery and solitary diamond jewellery whenever possible, as they are guaranteed to have been extracted under strict supervision, following the laws that serve to protect the diamond workforce, the mining areas native people and environment. Birks also requires that their cutters guarantee that all purchased diamonds are natural and untreated other than polished.
