Meet the Business Owner: Leibish P.
As the founder and president of LEIBISH, I helped pioneer the world of Fancy Color Diamonds online. My career began in the late 1970s as a diamond polisher, and in 1979 I entered the specialty field of Fancy Color Diamonds and rare Fancy Shapes.
In 1995, I launched our first website, transforming Leibish from a traditional B2B operation into one of the earliest international B2C destinations for rare colored diamonds. With the support of a dedicated team, we expanded into fine colored-diamond jewelry in 2001, building the foundation of the global brand LEIBISH is today.
We continue to operate as a leading diamond trader, an established online authority, and an active participant in major diamond and jewelry trade shows worldwide.
