People who wear designer jewellery on special occasions will feel more confident, according to Natasha Faith.Ms Faith, the co-founder and designer of La Diosa, said that designer jewellery demands attention and denotes power, which is increasingly important during the current troubled economic climate as people are more anxious.She told Professional Jeweller: "Jewellery is the most emotive accessory on this planet and like shoes it is to be worn on different occasions to reflect your mood."Everybody has days when they would like to feel confident, when they would like to be admired, when they would like to walk into a room and not have to say a word in order to noticed - don't they?"The Minogue sisters were both in the high fashion headlines for sporting a glittering array of trinkets and charms during the most recent episode of hit reality television show The X Factor.X Factor judge Dannii Minogue chose a selection of designer jewellery by Stephen Webster for Saturday's live show, which included earrings in yellow gold and set with white diamonds.The new mum wore Stephen Webster again for Sunday's live show, while her sister Kylie wore a glittering array of designer jewellery by Piaget, that included a selection of diamond earrings and rings.Meanwhile, jewellery designer Bobby White has responded to criticism of his advertising campaign, which features a naked lady posing proactively, by claiming that controversy is good for business.He told Professional Jeweller: "We always like to do shocking pics and it's worked for us. If you upset one person, you get business somewhere else."Designer jewellery is expected to be popular this Christmas despite the current economic climate tightening shopping budgets for many people, according to Beaverbrooks director Daniel Brown.Mr Brown told Profesional Jeweller that he believes the VAT increase in January will actually help sales of designer jewellery increase in the run up to Christmas.He said: "This year has been reasonably healthy and, despite the negative stories in the media, consumers appear to be fairly buoyant. Adding in people buying ahead to avoid the VAT increase, there are reasons to feel confident about this Christmas."Retail analyst Verdict has said that 2010 will be the best Christmas trading period for three years as they expect sales to increase by nearly two per cent to 85.2 billion with consumers forecasted to spend an extra 1.6 billion on presents and gifts.
