Crofts Jewellery Valuation Services

Monica Crofts, Owner, Registered Valuer Number  RV 270

Monica graduated with a Bachelor of Science from Sydney University and worked as a scientist for a number of years, before changing her field and completing the Diploma of Gemology in Sydney with the GAA (Gemological Association of Australia), the Valuers’ course with the NCJV (National Council of Jewellery Valuers), and also completing a Diamond correspondence course with the GIA (Gemological Institute of America), as at the time there was no Diamond grading course available in NSW.  She went on to lecture in Gemology and became Head Practical Demonstrator as well as becoming involved in the GAA Council up to the level of Vice- President, and represented NSW at Federal level conferences. 

On moving to Melbourne, Monica re-created her Valuation service inconjunction with her new husband, Ian Crofts, who was a Gemstone wholesaler.  Monica went on to serve on the Victorian NCJV Committee (National Council of Jewellery s) for some years as President and delegate to the National Committee. 

Monica is part-owner and grader for Australian Diamond grading Company, Scientific Gem Testing Laboratories (SGTL), who produce the Auscert and Gemcert certificates.
