David V. Thomas

David Vyvyan Thomas (born 1942) was the Crown Jeweller for the British monarchy. He worked for the Royal Family from 1991 until his retirement in 2007 as an employee of Garrard & Co. He still retains three Royal Warrants.
Thomas is the son of a Swansea chemist and originally worked for a competitor of Garrard's, but the rival company took an interest in Thomas and in 1986 they headhunted him. Prince Charles enjoyed his work so much that he recommended him to the Queen, and he eventually was appointed to take over from former Crown Jeweller Bill Summers.
He has been made a Member of the Royal Victorian Order for his services to the queen.
