Leibish & Co. was one of the very first fancy color diamond companies to go online. Founder Leibish Polnauer recognized early the Internet’s potential as a sales, marketing, and service channel to reach customers worldwide. At the start of the 21st Century, the company added jewelry manufacturing. It designs, manufactures, and markets jewelry made with color diamonds precisely calibrated for size, and graded for color. Its color diamond engagement rings are the company’s best sellers, although they create a wide range of jewelry from general items through to haute couture fine jewelry pieces. All Leibish & Co. diamonds and jewelry come certified with a GIA, Argyle, IGI, or in-house diamond certificates.
