If your jewelry is made of gold? What is the best quality?

Gold, in its purest form, is a very lustrous, dense, soft, malleable, and ductile yellowish metal that appears naturally most of the time. They are found in the form of nuggets or grains in rocks or river sediments.

Gold is characterized by being a very malleable metal that is often made with alloys with other metals to give it hardness. If you want to check the purity of a piece of gold that you have at home, you can always go to any of the Compare or stores, where we will carry out the necessary tests to check the quality of the pieces.

If you want to carry out a check at home, it is recommended to use a quality electronic scale that gives the weight with decimals, and to measure the dimensions, an electronic meter that indicates the decimals. Gold is one of the densest metals (Density = Mass / Volume). The density of 24 karat gold (99.9% purity) is 19.3 grams / cm3.

How to know if your jewelry is gold at home?

To check at home if the jewelry or coins you have are made of gold, there are different methods and you have to follow a series of checks.

Visual examination – you will have to look for a mark that determines the purity or carats of the jewel. You can also see if it has any discoloration, if the piece is worn and another hue is seen, it means that the jewel has only gold plating.

Use a magnet – gold isn’t a magnetic metal so gold should not be attracted to the magnet. If your jewel sticks to the magnet, it is not gold.

Checking the density – this is a check that requires a little more work and follows these steps:

  • Weigh the portion with an accurate scale and record the weight in grams.
  • Fill the measuring cylinder or measuring vessel with water with the measurement in millimeters.
  • Introduce the piece in the water and observe how many millimeters of water increases.
  • Perform the calculation: density = mass / displaced volume. If the result is close to 19, you have a 24 karat gold jewel.

Ceramic test – If when rubbing the gold piece on an unglazed ceramic plate, golden lines appear, the jewel is gold. However, if the stripes are black, the composition of the piece is not gold.

How is the quality of the gold checked?

Gold buying sector specialists at Compare or stores often recognize gold simply from the experience of working with it, just by looking and touching it, but they have different tests to check the quality of the gold when in doubt. :

  •  Gold Acid Test – In this test gold is rubbed gently with an Arkansas stone, leaving an imprint on the stone. When a drop of acid is added and there is no reaction or the metal does not disappear, it is gold.
  • X-ray test – allows to know the content of the precious metal, especially it is a useful method for jewels or large ingots. It does not damage the part and it is a very reliable method. A device called a spectrometer is used.
  • Gold cupellation – it is the safest test but the least practical, since the piece is melted in a furnace and, therefore, the piece has to be destroyed.

Knowledge is the key to knowing if something of value is being sold or not, but it is just as important to sell to reputable, experienced merchants who are recognized for their good care and service to their customers.

What types of gold are there?

We can differentiate different types of gold according to its degree of purity, which is measured in carats:

  • 24 carat gold: 24 carat gold degree of purity is 99.9%, which is why it is considered pure gold. It is a soft yellow metal bright and very malleable it does not react with almost any chemical product, although it can be sensitive to chlorine. Gold bars are usually 24 karat.
  • 18 karat gold: Known as high gold, it has a purity of 75%. It is the most commonly used type of gold among jewelers and goldsmiths as it is composed of 18 parts gold and 6 parts of other metals such as silver and copper. It is harder than pure gold, which makes it ideal for jewelry making.
  • 14 karat gold: Less known as gold, it is composed of 14 parts gold and 10 parts other metals hence has a purity percentage of 60%.
  • 12 karat gold: It is composed of 12 parts of pure gold and 12 parts of other metals, hence its purity is 50%.
  • 10 Karat Gold: This is one of the lowest forms of karat presentation of gold, with 10 parts pure gold and 14 parts of other metals, having a purity of 40%.

We can also differentiate types of gold according to its color:

  • Yellow gold: it is considered noble gold, it is almost not reactive, it is very soft, its color does not usually change or oxidize, it is gold in its pure color, it is usually 24 or 18 carats
  • White gold: it is usually presented in 18 carats and contains 75% fine gold and the rest is made up of a palladium alloy or a very special alloy called the Italian League.
  • Rose Gold: Rose gold has recently been introduced into jewelry and is cheaper than yellow. Its tone is the result of the combination of gold with silver and copper.
  • Red Gold: to obtain this color you just have to mix the gold with the copper.

These are the most commonly used gold colors in jewelry today, although we can also find green, gray, black or blue gold. Colors that, according to many designers, will be a trend in the coming years.
