Symmetry uses the very latest high-grade equipment to provide an unparalleled level of accuracy in its evaluations.

Our sister company Spectra Gem Laboratory is equipped with both infrared and ultraviolet spectroscopy and a research-grade binocular microscope for precise scientific coloured gem testing and grading reports.

to Detail

For a precise valuation of your jewellery, all facets must be individually appraised and compared against market demand and trends.

At Symmetry we have developed an eight-point valuation process to make sure our estimate of the item’s worth is as accurate as possible.

It’s a rigorous approach to valuation which embraces the latest technology, acid and electronic testing, weight and quality analysis, and manufacture identification.

Reasons for
a valuation

Having your jewellery independently valued is important for your own protection – you are taking a risk by not having it valued. Here are three key reasons:


Many valuations are for insurance purposes with most insurers insisting on an update every two to four years (refer to your insurer’s product disclosure statement).

Your insurance company may refuse to compensate you for the full value of your precious jewellery and gemstones if they have not been professionally assessed.

A claim for lost or stolen jewellery is far more likely to be favourably processed if you have a current valuation certificate.

Proof of

It can be very difficult to prove you own jewellery – or that it even exists – if you do not have a receipt or if it has been handed down through generations of family members.

A valuation certificate with a high definition photo is proof that the stolen or lost piece exists, it indicates the true value and is a record of possession.


An independent appraisal is vital to ensure you receive a good price when selling your treasures.

You are far more likely to receive a fair deal if you are armed with detailed information about your piece which matches it with market interest and trends.
