I am a former craftsman to the Crown Jewellers with over 38 years of experience and have now branched out on my own as a Freelance Precious Metal Polisher, as a result of my broad experience. I have many world famous trophies to my credit, namely The Premier League Cup, The World Cricket Cup, The Dubai Cup, The World Snooker Trophy, The Arlington Million, The Marsh Classic, 10000 Guineas and the America's Cup to name but a few. I have also been privileged to work in the jewel house in the Tower of London restoring a wine cistern which was made in 1830 and used only the once by Queen Victoria. I am currently working on lots of jewelry pieces for some very high profile celebrities Thanks to Gwen for letting me know about the forum.
