Bart Marks founded the Ice on Fire diamond brand because he truly believed there was a better way to cut a diamond. “In my heart I know an exquisitely formed, optically pure diamond crystal wants to be a Ice on Fire diamond and I think I can prove it.” Ice on Fire diamonds measures up, in every sense of the words, providing a bigger brighter whiter appearance even compared to other top rated diamonds. “Cutters need to make a lot of difficult choices,” Bart explains, “but choosing beauty over weight is what we do; it’s the art of diamond cutting. If you just want the diamond to be heavy, don’t cut it at all.”
