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 J, a diamond with a slightly detected 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.
