Other Method For Testing Gold


Look for a hall mark

A mark identifying the sort of gold will often be stamped on a piece of gold. A stamp reading “GF” or “HGP” designates an item as being gold-plated rather than pure gold. A pure gold item of jewellery, however, might have a “24K” or other fineness-designating stamp. Typically, hallmarks are found inside the ring band or close to the necklace clasp.

Be warned, nevertheless, that some trademarks can be imitated. This is why it’s crucial to consider a mark as only one of several authenticating factors. A very minor hallmark might exist. To see it clearly, you might even need a magnifying lens.

Check the piece’s edges for fading

Activate a bulb or bright light. Hold the object close to the light of the lamp. Rotate it in your palm so you can pay close attention to all of the edges. It’s probably wear on the plating if you notice that the margins of the gold seem faded or worn away. It follows that the object isn’t made of pure gold.

Check the piece’s surface for spots

Do you see any white or red spots on the object when you hold it up to a bright light? The spots could be quite small and challenging to see. Because of this, it’s crucial to carefully study the object, perhaps using a magnifying glass and a bright light. These blemishes suggest that the gold plating may be eroding, exposing the metal beneath.

Put a magnet up against the possible gold object.

Above the object, place a magnet. Reduce the magnet’s height until it nearly touches the surface of the object. The object is not pure if you experience a downward pull or draw on the magnet. The item also contains additional metals, like.
