About Us


Dr. E. Isaac Mostovicz

Dr. E. Isaac Mostovicz has worked in the diamond industry for 35 years. After training as a diamond polisher, he ran one of the two factories of S. Muller & Sons Diamonds NV, one of the most successful polishing operations in the world, becoming its CEO in 1990. Prior to this appointment, he established Allied Diamonds, which catered to jewelers both in the United States and Japan. This work experience allowed Isaac to become an expert in every facet of the diamond pipeline from mining, sorting and polishing through to servicing the diamond’s retail customer.   
Among his many milestones, Isaac has been a key player in introducing several iconic diamond cuts to the market, including the ‘Hearts and Arrow’ and ‘EightStar’ cuts. Under his guidance, S. Muller & Sons was the only company to successfully market the ‘De Beers Millennium Limited Edition Diamond’.
More recently, Isaac received his MBA and PhD, studying the psychology behind luxury consumption. He is a fellow of the Chartered Institute of Marketing (FCIM) and is a Chartered Marketer.
Isaac is the founder of Janus Thinking, a think tank focusing on the psychology of luxury, marketing, management, and leadership on which he publishes and lectures regularly. His ideas can be found on his blog, www.janusthinking.com.
Isaac is married with six children and four grandchildren.
Randy L. Pearson

Randy entered the diamond industry almost 30 years ago after graduating from North Carolina State University in Raleigh with degrees in mechanical, biological and agricultural engineering. For 11 years he managed one of Raleigh’s most established guild jewelry stores and was their diamond buyer and sales manager. Over the years he has completed several Professional Development courses at the Gemological Institute of America (GIA) in Diamonds, Diamond Grading, Colored Stones, Colored Stone Grading, and Gem Identification.

In 1998 he joined the US chapter of Allied Diamonds, Inc. and is currently its general manager. Allied Diamonds is a Registered Supplier for the American Gem Society (AGS), and Randy is a very active member serving on several committees. 

Under Randy’s guidance Allied Diamonds had some remarkable achievements, including having a key role in the marketing of the ‘De Beers Millennium Diamond Limited Edition’ and introducing the ‘Internally Flawless’ diamond to the retail consumer. Randy is a diamond authority, having created the ‘Alliance Program’ for top retail jewelers and regularly giving speeches, presentations, and workshops.

In 2015 Randy created Kahro Diamonds to service the diamond needs of the married couple, a project that takes most of his professional time.

Randy lives with his wife, Sherri, four children and two grandchildren in Raleigh. He is an Ordained Deacon at Thanksgiving Baptist Church, and he founded the Boy Scout Troop 422 with which he still volunteers. Randy’s two sons, Luke and Cole, have followed in their father’s footsteps to become Eagle scouts and members of the Order of the Arrow as well. Randy has also been a baseball coach for many years with local youth recreation leagues.
