Look for a signature. 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 jewelry, however, might have a "24K" or other fineness-designating stamp. Typically, hallmarks are found inside the ring band or close to the necklace clasp. [1]
Be mindful, 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 for fading at the piece's edges. 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 coating might 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's other metals, like nickel, are reacting to the magnet. A chunk of pure gold won't attract the magnet because it is non-ferrous.
When you apply vinegar to a surface, watch for a change in color. Fill a dropper with white vinegar and set it aside. Your metal object should be held firmly in your hand or placed on a table. A few drops of vinegar should be applied to the item. It is not pure gold if the drops cause the metal to change hue. It is pure gold if the color does not change.
Rub a jeweler's stone against your gold. On a table, place a black jeweler's stone. Take hold of your gold coin firmly. Use enough force to rub it across the stone to leave a mark. The piece is pure if the mark you made on the stone is substantial and golden in hue. The piece is probably plated or not made of gold if there is no line or merely a very weak one.
Use caution when using this technique to avoid hurting your valuables. Additionally, the appropriate kind of stone must be used else the marks will have no significance. A jeweler's stone is available from local jewelers or internet retailers who sell jewelry supplies.
Utilize a digital gold tester. You may get this small handheld tool online or from a jewelry supply store. It has a probe at the end. You apply conductive "tester" gel to a metal object to assess it. Typically, the same stores that offer testing equipment also sell this gel. Rub the probe against the item after applying the gel. It will be possible to tell if a metal is pure by how it reacts to electricity.
To ascertain the precise results, refer to the tester's instructions. A pure gold piece will have greater readings than one that has been plated since gold is a conductive metal.

To determine the gold karat purity more precisely, get an acid testing kit. One of these kits is available from a seller of jewelry-making supplies. Along with all the necessary supplies, the kit will also come with comprehensive instructions. Before starting, make sure to carefully read the directions and make an inventory of the supplies.
If purchased online, these kits can be found at reasonable prices. Starting prices are roughly $30.
