How can I ascertain that the bullion I bought from GSC is genuine?

When clients purchase bullion from GSC, they can be assured that they are buying genuine bullion as GSC acquires their bullion directly from the mints / refineries and reputable international dealers. We will then do random checks on each shipment with our various devices to confirm the authenticity.

In the very unlikely event that the bullion purchased from us is counterfeit or significantly lower purity / weight as stated on the product, we will be more than happy to provide a one to one exchange or full refund. Allow us to share with you the 3 devices we use to authenticate bullion and gold jewellery.

Densimeter

A densimeter evaluates the purity of precious metals (Gold, Silver and Platinum) by measuring the specific gravity of the sample and distinguish the precious metal from the other base material. Simply by measuring the weight in air and the weight in water, the programmed device will analyse and display the content of precious metals in terms of karats, purity and density. As it tests the average purity of the sample, it provides more accurate result for solid items for instance gold coins and bars.

The Magnetic Bullion Tester is a magnetic scale and measures the attraction or repulsion of the bullion to magnet in the device. A metal’s magnetism cannot be manipulated, and every metal reacts in its own way to a magnetic field. Precious metals like gold and silver are not magnetic, it is weakly repulsed by a magnetic field. Bullion can remain in their packaging during testing and this is non-destructive.  Multiple objects can be tested simultaneously with this tester, for example coins in a tube and if one is counterfeit, it will be picked up immediately by the magnetic bullion tester.

XRF Analyzer

XRF stands for X-ray fluorescence. XRF Analyzer is a powerful, non-destructive device for measuring a wide range of elemental composition from magnesium (Mg) to uranium (U), from parts per million to 100%. It emits X-rays that hit the sample, causes the elements in the sample to fluoresce and travel back to the analyzer’s X-ray detector. The analyzer will then count them and make mathematical calculations to generate a result. Results are available immediately

The above methods are different from some traditional methods you might have heard of, for example fire assay or using a stone and acid which are somewhat destructive. The devices that GSC utilises are non-destructive, accurate and instant. You need not worry about stains or scratches left on your precious metals after testing and are definitely more accurate and transparent.
