Identifying genuine gold in Egypt requires more than just a quick look at the hallmark. With the rise in sophisticated 'fake' gold pieces entering the market, protecting your investment is paramount.

1. The Magnet Test

First, always carry a strong magnet. Real gold is not magnetic; if your piece is attracted to the magnet, it likely contains iron or nickel. However, this test alone is not conclusive, as other non-magnetic metals are often used in fakes.

2. The Stamp Test (Maslahat al-Damgha)

In Egypt, the Hallmarking and Weights Department (Maslahat al-Damgha) stamps all legitimate pieces. Look for the distinctive Egyptian hallmarks for 18k, 21k, or 24k. The authentic Egyptian eagle or lotus flower stamp is notoriously difficult to replicate perfectly.

3. The Density Test

Gold is an extremely dense metal. Using a precise scale and a water displacement method, you can calculate the density of larger bullion. Pure gold has a density of approximately 19.3 g/cm³.

4. Professional Tools and Invoices

The most reliable professional method is the 'Acid Test' or X-ray fluorescence (XRF) analysis, typically performed by trusted specialists in Al-Muizz Street or major neighborhood jewellers.

Never buy gold without a formal invoice ('Fatoura') that specifies the weight, carat, and purity, as this is your only legal protection if a discrepancy is found later. Professional investors also look for 'Brand Verification' on modern bullion bars from companies like BTC or Sam Gold, which now include NFC chips or laser-engraved serial numbers.
