The value of gold is based on the karat system, which is a 24-point scale signifying the percentage of gold a piece of metal contains.So, if gold jewelry is 14K, it is 14 out of 24 parts gold, or 58.33 percent gold.
Collectors of gold know that this precious metal has unique properties that can be identified through careful examination. You can learn to identify genuine gold and avoid being misled through devious practices. Protect your assets and be certain that the gold you buy matches the published claim.
Any gold that is marked less than 10k (41.7% purity) is considered fake.
Anyone who is familiar with the different levels of quality will quickly recognize the following markings:
GP➡️ Gold Plated.
GF➡️ Gold Filled.
GE➡️ Gold Electroplated.
GEP➡️ Gold Electro Plated.
HGP ➡️ Heavy Gold Plated.
HEG➡️ Heavy Gold Electroplated.
These markings indicate that only a small percentage of gold was used to cover a piece that was made out of some other kind of metal in order to give it the appearance of gold.
To give you an idea of how the upper levels of purity stack up next to one another: 24k gold is 99.9% pure, while 18k gold is 75% pure. Absolutely 100% pure gold is unheard of, mainly because pure gold is very soft and wouldn’t make for a durable piece of jewelry.
How to Test Gold Jewelry.
Jewelers make an impression in each gold piece of jewelry designed and crafted from genuine molten gold bullion. On necklaces and bracelets, this stamp is on, or near, the clasp. Rings have a stamp somewhere on the inside surface. A jeweler’s loupe is sometimes required to see the tiny stamp placed on fine gold jewelry. The jewelry stamp will include the karat, also called the purity, of the piece, such as 14K or 24K. Close to this stamp is the manufacturer’s stamp, which further clarifies genuine gold jewelry.
You might have an older piece of jewelry that does not have a jewelry mark, which could make you wonder if the piece is counterfeit. You will want to conduct additional tests on the piece.
1. The Acid Test.
All precious metals can be tested through the use of an acid test that will only harm fake materials. Genuine gold will stand up to your attempt to conduct a nitric acid test at home. Make a tiny mark on the piece of gold to penetrate the surface. Drop a small amount of liquid nitric acid on that scratch and wait for a chemical reaction. Fake gold will immediately turn green where the acid is. Gold-over-sterling silver will become milky in appearance. Gold will not react to the nitric acid. The desired result is a clear drop of liquid that does not change color.
2. The Magnet Test.
Genuine gold will not attract a magnet. The magnetic test is the most convenient and portable test for genuine gold, since the magnet can be carried around in your pocket. Imitation gold and other alloys will attract the magnet. Coins can appear to be gold, when in fact the surface is simply gold in appearance. The magnet would reveal the underlying metal.
3. Using the Float Test.
A cup of water is all you need for another important test. Any size piece of genuine gold will immediately sink to the bottom of any liquid. Imitation gold floats or hovers above the bottom of the container. In addition, real gold will not rust or discolor when wet.
4. Skin Test.
Skin discoloration from wearing fake gold jewelry is not a myth. For this test, simply hold the gold in your hand for a few minutes. Perspiration on the skin creates a chemical reaction with the gold. Skin will discolor (a black or green color) if the gold isn’t real. Genuine gold will not react with the skin. Jewelers can determine the contents of any gold piece of jewelry. Certified consultants will conduct further tests that reveal the genuine gold weight and purity.
5. The Size and Weight Test.
Gold is denser than most other metals. If you have a piece that looks too large for its weight or feels too light for its size, then you probably have fake gold.
Bullion coins are actual coins made from precious metals, including gold, silver, palladium, or platinum. They serve as collectibles, investments, or as a hedge against inflation .
6. The Ceramic Scratch Test.
Take an unglazed ceramic plate or piece of tile and scrape a piece of gold across its surface. Real gold will leave a gold mark or trail. Other metals will leave a black trail.
