Hasenfeld-Stein has a reputation of selling some of the most extraordinary Rounds, Asschers, Cushions, Emeralds, and Princesses. But, we are most proud of is our FireMark® brand of diamonds, which is not only exclusive and patented, but one of the most brilliant diamonds in the world. In fact, our FirePrincess® consistently rivals an Ideal Round in brilliance, with an average 98% light return. Our FireCushion® is a GIA Excellent/Excellent, (not a Modified Brilliant), and has a more brilliant and larger appearance than any other Cushion in the marketplace today.
