Higher value items sold by Grays Online come with a Certificate of Authenticity which lists an Estimated Replacement Valuation which is based on current Australian market forces.

The Certificate of Authenticity means that the actual item for sale has been assessed by a fully qualified specialist jewellery valuer. The specialist jewellery valuer requires knowledge of gemmology, jewellery manufacture, precious metal markets, world gem markets, supply and demand factors both overseas and within Australia, taxation law requirements, general retail practices and the final combination of all the above factors in the principle and procedures of a jewellery valuation. They inspect and assess the jewellery item using a hand lens taking note of several key factors-

• 1.Metal types, hallmark type stamping, confirmation of gold carats by way of gold testing, approximate metal weights and type of manufacture
• 2.Verification of gemstones using gemmological testing equipment to verify stone family and type, gemstone authenticity, measuring for size and calculating approximate stone weights
• 3.Grading of gemstones by cut, colour and clarity of such stones
• 4.Detection of any treatments to the gemstones
• 5.A specified full description of the jewellery article with a clear photo of the individual item.

The Estimated Replacement Value does not represent a retail price or resale value of the item. It is an estimated value of the cost of replacing the item and is the opinion of the registered jewellery valuer based on the criteria detailed above. Variations may occur due to market fluctuations.
