Since opening in 1998 Symmetry has become one of Australia’s leading independent jewellery valuers.

Principal Kym Hughes is highly respected in the valuation industry with extensive experience and knowledge of the manufacturing techniques of modern and antique jewellery from around the world.

Her rigorous appraisal process is supported by sophisticated analytical equipment which can accurately test the origin, type and treatment of gemstones. The testing is performed by Symmetry’s sister company Spectra Gem Laboratory, one of the best equipped gemstone analytical laboratories in Australia.

Symmetry is also fully independent. We do not trade in jewellery or have corporate alliances with other companies such as insurance organisations.

For customers this is an important point of difference. It means we have no conflict of interest and work solely with you to deliver accurate, unprejudiced valuations.


Under current Australian law, tertiary qualifications are not required to operate as a jewellery valuer. This is not the case with Symmetry.

Kym Hughes has more than 25 years experience in the industry and regularly undertakes professional development to keep up-to-date with current best practice. Her training and qualifications include:

  • Diploma in Gemmology, FGA (UK)
  • Diploma in Gemmology, FGAA (Australia)
