Grandview Klein Heritage

For three generations, Grandview Klein has been renowned for its diamond cutting expertise and devotion to its clients.

Our philosophy is simple: to provide every client with the perfect diamonds. Our access to superior rough diamonds as well as our state-of-the-art factories around the world allows us to deliver the most exquisitely cut stones to our clients.

Our dedication to craftsmanship, trust, and integrity has led us to become one of the largest diamond manufacturers and direct suppliers worldwide, boasting sales offices in New York, Tel Aviv, and Hong Kong.

As Sightholders since 1981, our massive inventory has diamonds for every retailer’s needs, from 1 to 2-carat diamond rings to rarer diamonds as large as 100+ carats to exquisite yellow, pink and blue diamonds.

Core Values

Here at Grandview Klein, we have several core values that absolutely underpin our company philosophy and guide our day-to-day operations. By maintaining these core values, regardless of how we or the market change, we can preserve what has always been special about our company. The following core values are the essence of our company:


Selling the highest quality natural diamonds


Creating and maintaining a mutually-beneficial partnership with our customers


Supporting the industry and communities in which we do business


Conducting ourselves with integrity in everything we do

Ethical Sourcing

As a result of the Grandview Klein Diamond Group's longstanding commitment to business, social, and environmental ethics, we have aligned with the Diamond Trading Company's Best Practice Principles to ensure total integrity throughout the entire diamond pipeline from the sourcing of rough stones to the manufacturing, processing, marketing, and distribution of polished diamonds.
