What is a “flawless diamond”? Almost every diamond contains natural inclusions. If no such inner flaws can be seen under tenfold magnification, the diamond is considered internally flawless. The classification of a diamond according to the internationally recognized grading table takes into account the number and size of its inclusions, as well as their type, position, and color. Only a diamond that has earned a clarity grade of SI (small inclusions) or better can satisfy our strict quality standards and become the star of our diamond jewelry, as for example in the One by Wempe Classics ring.
