About Hasenfeld-Stein

Over 70 years ago, my father, Alexander Hasenfeld, began his career in the diamond industry. He started the business with one premise and a philosophy which resonates just as much today as it did back in 1948 : “Do what you do best, and do it better than anyone else”. We take those words to heart and it is in that belief that we have become one of the leading Diamontaires in the industry. We say that, not to boast, but with a reverence for the companies who have allowed us to be who we are today – our most trusted retail partners.

Meeting your expectations is at the heart of what we do. You can say we’re perfectionists. We’re proud of that word. What separates us from the multitude of diamond companies in the business, is not only the quality of our diamond cuts, but the relentless pursuit of such perfection.

So why work with Hasenfeld-Stein?

There are some important differences:

  • We never cut a diamond for yield. We reduce yield to make a more beautiful diamond.
  • We are the owners and creators of the FireMark® brand of diamonds – which include our patented FirePrincess® and FireCushion® diamonds.
  • We protect our retail partners. We offer:
    • Exclusivity
    • Easy terms
    • Affordable buy-in levels
    • Marketing support (link to Marketing Materials page)
    • Responsible sourcing
  • We own our factories. We cut our Rounds, Generic fancy shapes (Asschers, Cushions, Emeralds and Princesses), and FireMark® branded diamonds in our New York and China factories.

Get to know us. Our business is built on the foundation of customer first and building your diamond business. It’s what my dad set out to do in 1948. And, what the Hasenfeld-Stein family continues to do today.
