Ratner joined the family business in 1966 and built up an extremely successful chain of jewellers during the 1980s, of which he was
CEO. The shops shocked the formerly staid jewellery industry by displaying fluorescent orange posters advertising cut-price bargains and by offering low price ranges. The Ratners Group consisted of Ratners,
H. Samuel,
Ernest Jones, Leslie Davis,
Watches of Switzerland, and over 1,000 shops in the United States, including
Kay Jewelers. Although widely regarded as "tacky", the shops and their wares were nevertheless extremely popular with the public, until Ratner made a speech addressing a conference of the
Institute of Directors at the
Royal Albert Hall on 23 April 1991. During the speech, he commented: He compounded this by going on to remark that one of the sets of earrings was "cheaper than a prawn sandwich from
Marks and Spencer's, but I have to say the sandwich will probably last longer than the earrings". Ratner made a guest appearance on TV chat show
Wogan the day after his speech, where he apologised and explained his joking remark that some of his company's products were "total crap". Ratner's comments have become textbook examples of why CEOs should choose their words carefully. In the furore that ensued, customers stayed away from Ratner shops. After the speech, the value of the Ratner Group plummeted by around £500 million, which very nearly resulted in the group's collapse. Ratner hired a chairman in an attempt to stabilise the situation, and was dismissed by the new company chairman in November 1992. The group changed its name to
Signet Group in September 1993. Ratner has said that his remarks were not meant to be taken seriously. He blamed what he called aggressiveness and deliberate misinterpretation by several
media outlets for the severe consumer reaction. which ceased trading in 2014. In 2013, during a visit to India for the inaugural eTailing India Expo, Ratner announced that he would be entering the Indian market. In December 2025, it was reported that Ratner was trying to acquire H Samuel and Ernest Jones in the UK, brands he once owned through Ratner Group, from Signet Jewellers. ==Personal life==
