New York diamond specialist Fraser Brown, originally of Portaferry, knows everything there is to know about his trade. Jane Hardy caught up with him on a recent trip home When J-Lo wanted something sparkly and several carats to wear on Oscar night, and Ralph Lauren needed some rather special gems to incorporate into the gold stirrup-themed jewellery used in the 40th birthday celebrations of his label, their diamond bracelets and agents called on Fraser Brown, one of New YorkТs specialist diamond dealers and an innovative gemstone rings in his own right. УWe were close to the goldsmith involved in Ralph LaurenТs 40th anniversary and helped conceptualise some ideas which led to some wow pieces. And IТm also very close professionally to Lorraine Schwartz who supplied the jewellery for J-Lo at the Oscars,Ф Fraser reveals. So it was natural for Diet Coke to invite the Portaferry-born diamond expert to create individual pieces of jewellery for the 10 Northern Ireland winners Ч 50% of the total Ч of their Diamond competition this summer. Fraser (37) has enjoyed the task and says: УTheyТve given me carte blanche and the diamonds given away as prizes are one carat which would cost anything from ?5,000 to ?7,000 on the open market.Ф He has designed a sapphire and diamond heart necklace, conventional rings and a diamond navel ring for Marcella, a truck driver from Limerick. How did he feel about that? УItТs her buzz and so I was happy to do it.Ф
