Guided by exacting standards, every diamond is thoughtfully chosen and seamlessly integrated into our designs. At Birks, we transcend the ordinary, ensuring that every facet of your love story mirrors the exceptional quality of our diamonds.


Diamond carat measurement determines the weight of a diamond, with one carat equaling 200 milligrams. At Birks, each diamond is carefully chosen and masterfully cut to maximize its beauty and brilliance at every carat weight.


The GIA colour scale refers to the natural tint in diamonds, a symphony ranging from D (colourless) to Z (light yellow). Birks’ curated assortment of diamonds range from D to I colours, a testament to our commitment to exquisite beauty and quality.


From the depths of the earth, diamonds emerge with tales of their journey. Within their intricate forms lie inclusions and blemishes mapping their unique passage. This natural process can result in a variety of “inclusions” (internal characteristics) and “blemishes” (external characteristics). Birks offers diamonds ranging from IF (internally flawless) to SI1 (small inclusions, nearly flawless to the naked eye). Our experts evaluate each unique diamond to ensure its exquisite quality.


Birks diamonds are cut to reflect and refract the light for maximum brightness and sparkle. With skilled hands, artisans sculpt perfect proportions and angles, where diamonds harness and reflect the very essence of radiance. A finely proportioned diamond, cut by only the most skilled artisans, will result in the best combination of brilliance, dispersion and scintillation.
