Nurhan Gumus


You can say Nurhan was destined for the jewelry business from birth.  Nurhan’s Great-Grandfather on his father’s side, Nishan Terdzakian, owned a jewelry store in the most prestigious quarter of the Grand Bazaar called Iç Bedestan.  Due to political events that targeted minority populations in what was the Ottoman Empire, it is difficult to know prior to Nishan’s time what exact trades the family were in.  However, it is safe to assume, even well before Nishan’s time, Nurhan’s ancestors were involved in the business for trades in Armenian culture are typically passed down through the family.

On the other side of the family, Nurhan’s uncle, Massis, apprenticed in the Grand Bazaar.  He in turn apprenticed Nurhan beginning when he was just 11 years old.  Massis decided to immigrate to the USA in the late 1970s and turned a few hundred dollars into a multi-million dollar jewelry manufacturing and retail business.  Like many first generation immigrants to the United States, Nurhan was expected to work in the family business.  Nurhan would come after school to the business to learn his craft and by 16 was the youngest recipent of  the People’s Choice Award at the Las Vegas International Jewelry Show.  By 17, he was overseeing the jewelry manufacturing for over 40 businesses and designers.

On a visit back to Istanbul, Nurhan saw a huge opportunity for a jewelry business that is not possible in the States.  His passion is to continue developing the old techniques the Grand Bazaar’s master jewelers are known for.  He realized that with his American business experience and complete jewelry manufacturing expertise, the possibilities for jewelry creativity in Istanbul are endless.  Nurhan  began integrating himself into the jewelry market in Istanbul when another twist of fate introduced him to Avni.

Avni Yalcin


Avni was also born in Istanbul like Nurhan, albeit to a Turkish family.  Their focus on education was high and they were amused by their young son taking apart all the machines in their house to try to figure out how they worked.  Life in Turkey was not easy for most Turkish families in the early 1980s, but Avni’s parents enrolled him in great schools and believed education was the key to success.  When Avni’s parents bought their first computer, Avni of course did the same thing to that and vowed to become a pro in technology.

Avni and Nurhan were first introduced to each other through their wives at a traditional dinner of mezes (appetizers), fish, and Rakı (aTurkish liquor) on the shores of the Bosphorus.  Over the course of the conversation at dinner, Nurhan became impressed with Avni’s skills.  Avni writes in more than 20 codes (computer languages).  He has made software and apps for government organizations, educational institutions, multi-national corporations, and some of the world’s most popular sports teams among others.  He has vast experience in creating web portals, the management of content, and automation of distribution channels.

Best of all, though, Avni has the know-how to implement the various forms of technology critical for a 21st century business.  He is quick to create solutions for problems that arise organically in a growing business.  He thinks not only from a company’s perspective, but also from a consumer’s perspective.  Most importantly, he thinks up a solution based in technology for just about everything because technology is his passion.  Avni began integrating himself into Nurhan’s business over the course of the next year and hasn’t looked back.
