Nader Kash

Raised in New York, Nader Kash started his career in Diamonds as a salesman for an Antwerp based Sightholder. Without a diamond industry background, Nader’s calling became quite clear from the first time he louped a diamond. It was an inherent feeling which has grown to Nader’s true passion. After four years of rapid growth, Nader was offered a position to head the development of a new diamond company. Built from the ground up, he led this organization to becoming a DTC Sightholder as well as one of the largest wholesalers of certified Canadian diamonds worldwide. In 2010, he launched Nader Kash International, a New York City based diamond house specializing in exceptional fancy shape loose diamonds, perfectly matched layouts, and exquisite fine jewelry. By integrating his genuine passion for diamonds and working closely with his esteemed clients, Nader is doing what he does best, procuring and supplying fine diamonds to the most discerning clients.


Our Philosophy

Our diamonds are our difference.

We work diligently to source the most exquisite makes available and we stand behind the quality of every stone in our stock. To find out more about our shapes, layouts, and matched pairs visit our Products and Partners page.

Exceptional service is the core of our business.

As a young but experienced company we believe in thinking differently. We go above and beyond for every customer and on every call, continually seeking new ways to deliver beyond expectations and industry standards. Our quality of service remains at the heart of every transaction. No request is too large or too small for our staff to attend to.

We believe in transparency and honesty.

We believe in transparent business dealings. We do not list our stock on 3rd party retail sites. We never sell our stock with inflated or unreasonable margins, always working to bring value to our customers and build lasting relationships above all else. 

We are dedicated to ethical practices.

We work to ensure that all diamonds within our sphere of influence are impeccably sourced with stringent standards of verifiable origin. We provide independent certification from the Gemological Institute of America (GIA) and retain a GIA Graduate Gemologist on staff. We work in full accordance with the Patriot Act and U.N. Resolutions.
