Free from the war and German occupation,
the Kotlars emigrate to the USA. Harry works
for a family-owned clothing factory in
Los Angeles. He quickly befriends the owners, who are smitten by his natural charisma and talent. The owners soon ask Harry to use his people skills as manager of the factory.
After witnessing Harry’s personable approach to management, the owners offer him the role of business partner. Harry consults Helen, and they both agree to nurture their own dreams instead.
Helen’s brother Aria sends small diamonds from his small diamond cutting factory in Israel. Harry sells these stones in the Los Angeles diamond district. He eventually leaves the clothing company to focus on selling cut stones.
Harry supplies diamonds to manufacturers and dealers, closing each deal with the same personalized service and charm he showed while working for the textile company.
Harry & Helen's dream begins to bloom.
The market responds favorably to Harry’s products and exceptional service. Clients feel confident in his wares, and this leads to orders for larger stones. Harry graciously entertains their requests and starts supplying .30 to .50 carat stones this year.
Demand later grows for even larger stones. While other suppliers exist in the market, many buyers specifically seek out Harry Kotlar. To meet this demand, he starts selling 1 to 2 carat stones.
With greater sales and better relationships with customers, business continues to prosper.
Members of the Kotlar clan joined the company.
Basha Kotlar Wiener and Louis Wiener shared Harry Kotlar's dedication to customer relations, and are instrumental to maintaining the company's steady growth.
The Kotlars start supplying stones up to 8 carats to large jewelry manufacturers and diamond dealers. Many of these stones end up in the collections of powerful executives & famous celebrities.
