Our systematic and scientific approach provides a true and accurate valuation

Symmetry utilises an eight-point appraisal process for analysing jewellery and assessing its real worth. It’s a rigorous approach which involves individually testing all facets of the piece and then checking it against current market demand.

  • 1.

    Purpose of the Appraisal

    This is confirmed with the customer and is important as the valuation needs to reflect the market use of the jewellery. For example, if it is for insurance purposes, a family law hearing or private sale.

  • 2.

    Metal Tests

    Metals are tested using acid or electronic analysis to determine the caratage of the jewellery, e.g. 9ct, 14ct, 18ct etc.

  • 3.

    Gemstone Identification

    Gemstones are identified using a x10 loupe eyeglass or more complex techniques involving a binocular microscope, ultra violet light testing or refractive index analysis.

  • 4.

    Mass Diamond Screener

    Diamond jewellery, including loose or mounted stones, are then analysed by the mass diamond screener to determine the authenticity of the diamonds. With less than 0.5 percent of diamonds needing further testing.

  • 5.

    Quality Analysis

    Grading of the gemstone is achieved through detailed analysis of its colour, cut and clarity.

  • 6.

    Size Analysis

    The gemstone is measured and its weight calculated.

  • 7.

    Manufacture Identification

    An assessment is made of how the item was manufactured, such as cast, handmade or a combination of both.

  • 8.

    Type and Quality of Settings

    Each type of setting within a piece of jewellery is individually assessed for its quality and complexity as it can affect the overall valuation. There may be more than one type of setting, such as grain, claw, rubover and channel etc.

  • 9.

    Valuation Certificate

    Each component of the piece, including the mount, settings and gemstones, are then given a price. These are combined to establish an estimated value based on the market purpose of the jewellery. The valuation is then recorded on an appraisal certificate together with a high definition photograph of the item.

Assessing Market Value

Symmetry’s valuation takes into account the intended market use of the jewellery. The market value will vary depending if the jewellery is to be sold and the type of sale.

  • Retail

    The value of a lost or stolen item if it has to be replaced from a traditional jewellery shop. This valuation is usually for insurance purposes.

  • Auction Reserve

    The minimum price which the owner could expect to achieve at an auction, excluding premiums and commissions of the auctioneer.

  • Fair Market Value

    A second-hand price in a respectable or specialised market between a willing buyer and seller.

  • Forced Sale

    The expected price of an item which has to be sold quickly in non-ideal market conditions.

  • Second-hand

    An appraisal based on the condition of the jewellery and current market trends.

  • Private Sale

    The price that you could expect to achieve by selling jewellery to a member of the public, excluding GST, and sales and duty tax.

  • Divorced Property Settlement

    The Family Court will often issue instructions for a valuation based on fair market value.

  • Deceased Estate

    A valuation which reflects current market value subject to instructions from the solicitor.
