PrincessPlus has been designed and manufactured by EFD – the world experts in princess cut diamonds. EFD has been specializing in squared edged fancy diamonds for over two decades. After years of improving and perfecting the standard princess cut, there was no-one more capable or qualified to create a superior Princess cut diamond.

EFD is a family owned company, with offices that span the globe, including New York, Los Angeles, Belgium, Israel, Thailand, China, Hong Kong, and soon to be Australia; and a factory location in the North of Thailand, where over 1500 skilled workers cut and polish the rough diamonds.

As a Diamond Trading Company Sightholder, EFD is one of a select group of companies with direct and consistent access to rough goods that come directly from mines compliant with the Kimberly process. Sightholding companies adhere to a strict set of ethical principles that include concern for human rights and our refusal to use any conflict diamonds, or blood diamonds.

Half a century after the company’s founder first entered the diamond industry, EFD has grown into one of the world’s largest and most influential diamond manufacturers in the industry.
