About JEMS & ValuGem

History and Who We Serve

VALUGEMwas established in 1995 and JEMS(Jewellery Evaluation & Mediation Services) in 1999, both formed by Peter Buckie and Barbara Leal.

  • Experienced
  • Qualified
  • Respected

In 2016, it was decided that Peter would operate JEMSconcentrating on the legal and more diverse jewellery related commissions, whilst Barbara would run VALUGEM, specialising in the more predominant valuation, advisory and associated appraisal work.

There is an inevitable cross-pollination between the two enterprises, with Barbara providing the mainstay of research work necessary in JEMSand Peter offering advice and consultancy services to ValuGem.
