In addition to being awarded the prestigious AGS® Ideal cut grade, Masterpiece® diamonds must also exhibit the coveted "hearts and arrows" patterning, which is the hallmark of mastering craftsmanship and artistry. Frequently referred to "super ideals," only the world's highest performing and most precisely cut diamonds qualify for the Helzberg Masterpiece Collection.



When you look at a diamond under the ASET, it creates a color-coded image that clearly identifies its light performance and optical symmetry.



Because our Masterpiece diamonds are selected from superior rough diamond crystals, precisely cut and expertly polished, they are awarded the highest grade from the American Gem Society - AGS Ideal 0.



Every Helzberg Diamond Masterpiece is laser inscribed with its own serial number, identifying it as a true work of art.
