What makes a Tiffany & Co. diamond?

A diamond's quality depends on a combination of the 4Cs – color, clarity, cut and carat weight. However, Tiffany & Co. believes the most critical of these is diamond cut. More than any other factor, cut determines the brilliance, fire and overall beauty of your diamond. If a diamond is cut poorly, it will appear dull even if it has a high color and clarity grade.


Tiffany is committed to crafting the most expertly proportioned diamonds. In our workshops, nearly 1,500 of the world’s most talented cutters and polishers craft diamonds to the highest standards. This precision is what sets Tiffany diamonds apart.
